Detail

Problem Description:

Updated kernel packages that fix various security issues and several bugs are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux operating system.

These updated packages fix the following security issues:

* the absence of a protection mechanism when attempting to access a critical section of code has been found in the Linux kernel open file descriptors control mechanism, fcntl. This could allow a local unprivileged user to simultaneously execute code, which would otherwise be protected against parallel execution. As well, a race condition when handling locks in the Linux kernel fcntl functionality, may have allowed a process belonging to a local unprivileged user to gain re-ordered access to the descriptor table. (CVE-2008-1669, Important)

* a possible hypervisor panic was found in the Linux kernel. A privileged user of a fully virtualized guest could initiate a stress-test File Transfer Protocol (FTP) transfer between the guest and the hypervisor, possibly leading to hypervisor panic. (CVE-2008-1619, Important)

* the absence of a protection mechanism when attempting to access a critical section of code, as well as a race condition, have been found in the Linux kernel file system event notifier, dnotify. This could allow a local unprivileged user to get inconsistent data, or to send arbitrary signals to arbitrary system processes. (CVE-2008-1375, Important)

Red Hat would like to thank Nick Piggin for responsibly disclosing the following issue:

* when accessing kernel memory locations, certain Linux kernel drivers registering a fault handler did not perform required range checks. A local unprivileged user could use this flaw to gain read or write access to arbitrary kernel memory, or possibly cause a kernel crash. (CVE-2008-0007, Important)

* the absence of sanity-checks was found in the hypervisor block backend driver, when running 32-bit paravirtualized guests on a 64-bit host. The number of blocks to be processed per one request from guest to host, or vice-versa, was not checked for its maximum value, which could have allowed a local privileged user of the guest operating system to cause a denial of service. (CVE-2007-5498, Important)

* it was discovered that the Linux kernel handled string operations in the opposite way to the GNU Compiler Collection (GCC). This could allow a local unprivileged user to cause memory corruption. (CVE-2008-1367, Low)

As well, these updated packages fix the following bugs:

* on IBM System z architectures, when running QIOASSIST enabled QDIO devices in an IBM z/VM environment, the output queue stalled under heavy load. This caused network performance to degrade, possibly causing network hangs and outages.

* multiple buffer overflows were discovered in the neofb video driver. It was not possible for an unprivileged user to exploit these issues, and as such, they have not been handled as security issues.

* when running Microsoft Windows in a HVM, a bug in vmalloc/vfree caused network performance to degrade.

* on certain architectures, a bug in the libATA sata_nv driver may have caused infinite reboots, and an "ata1: CPB flags CMD err flags 0x11" error.

* repeatedly hot-plugging a PCI Express card may have caused "Bad DLLP" errors.

* a NULL pointer dereference in NFS, which may have caused applications to crash, has been resolved.

* when attempting to kexec reboot, either manually or via a panic-triggered kdump, the Unisys ES7000/one hanged after rebooting in the new kernel, after printing the "Memory: 32839688k/33685504k available" line.

Red Hat Enterprise Linux 5 users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188

Title: DSA-1565 linux-2.6 -- several vulnerabilities
Description: Several local vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems: Cyrill Gorcunov reported a NULL pointer dereference in code specific to the CHRP PowerPC platforms. Local users could exploit this issue to achieve a Denial of Service (DoS). Nick Piggin of SuSE discovered a number of issues in subsystems which register a fault handler for memory mapped areas. This issue can be exploited by local users to achieve a Denial of Service (DoS) and possibly execute arbitrary code. David Peer discovered that users could escape administrator imposed cpu time limitations (RLIMIT_CPU) by setting a limit of 0. Alexander Viro discovered a race condition in the directory notification subsystem that allows local users to cause a Denial of Service (oops) and possibly result in an escalation of privileges.

Title: DSA-1503 kernel-source-2.4.27 -- several vulnerabilities
Description: Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems: infamous41md reported multiple integer overflows in the Sbus PROM driver that would allow for a DoS (Denial of Service) attack by a local user, and possibly the execution of arbitrary code. Doug Chapman discovered a potential local DoS (deadlock) in the mincore function caused by improper lock handling. Eric Sandeen provided a fix for a local memory corruption vulnerability resulting from a misinterpretation of return values when operating on inodes, which have been marked bad. LMH reported a potential local DoS which could be exploited by a malicious user with the privileges to mount and read a corrupted cramfs filesystem. LMH reported a potential local DoS which could be exploited by a malicious user with the privileges to mount and read a corrupted ext3 filesystem. LMH reported a potential local DoS which could be exploited by a malicious user with the privileges to mount and read a corrupted ext2 filesystem. Marcel Holtman discovered multiple buffer overflows in the Bluetooth subsystem which can be used to trigger a remote DoS (crash) and potentially execute arbitrary code. Ilja van Sprundel discovered that kernel memory could be leaked via the Bluetooth setsockopt call due to an uninitialised stack buffer. This could be used by local attackers to read the contents of sensitive kernel memory. Masayuki Nakagawa discovered that flow labels were inadvertently being shared between listening sockets and child sockets. This defect can be exploited by local users to cause a DoS (Oops). Thomas Graf reported a typo in the DECnet protocol handler that could be used by a local attacker to overrun an array via crafted packets, potentially resulting in a Denial of Service (system crash). A similar issue exists in the IPV4 protocol handler and will be fixed in a subsequent update. Florian Zumbiehl discovered a memory leak in the PPPOE subsystem caused by releasing a socket before PPPIOCGCHAN is called upon it. This could be used by a local user to DoS a system by consuming all available memory. Wojciech Purczynski discovered that pdeath_signal was not being reset properly under certain conditions which may allow local users to gain privileges by sending arbitrary signals to suid binaries. Alan Cox reported an issue in the aacraid driver that allows unprivileged local users to make ioctl calls which should be restricted to admin privileges. PaX team discovered an issue in the random driver where a defect in the reseeding code leads to a reduction in entropy. Alex Smith discovered an issue with the pwc driver for certain webcam devices. If the device is removed while a userspace application has it open, the driver will wait for userspace to close the device, resulting in a blocked USB subsystem. This issue is of low security impact as it requires the attacker to either have physical access to the system or to convince a user with local access to remove the device on their behalf. Venustech AD-LAB discovered a a buffer overflow in the isdn ioctl handling, exploitable by a local user. ADLAB discovered a possible memory overrun in the ISDN subsystem that may permit a local user to overwrite kernel memory by issuing ioctls with unterminated data. Blake Frantz discovered that when a core file owned by a non-root user exists, and a root-owned process dumps core over it, the core file retains its original ownership. This could be used by a local user to gain access to sensitive information. Cyrill Gorcunov reported a NULL pointer dereference in code specific to the CHRP PowerPC platforms. Local users could exploit this issue to achieve a Denial of Service (DoS). Nick Piggin of SuSE discovered a number of issues in subsystems which register a fault handler for memory mapped areas. This issue can be exploited by local users to achieve a Denial of Service (DoS) and possibly execute arbitrary code. The following matrix lists additional packages that were rebuilt for compatibility with or to take advantage of this update: We recommend that you upgrade your kernel package immediately and reboot the machine. If you have built a custom kernel from the kernel source package, you will need to rebuild to take advantage of these fixes.

Title: DSA-1504 kernel-source-2.6.8 -- several vulnerabilities
Description: Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems: LMH reported a potential local DoS which could be exploited by a malicious user with the privileges to mount and read a corrupted cramfs filesystem. LMH reported a potential local DoS which could be exploited by a malicious user with the privileges to mount and read a corrupted ext2 filesystem. LMH reported an issue in the minix filesystem that allows local users with mount privileges to create a DoS (printk flood) by mounting a specially crafted corrupt filesystem. OpenVZ Linux kernel team reported an issue in the smbfs filesystem which can be exploited by local users to cause a DoS (oops) during mount. Ilja van Sprundel discovered that kernel memory could be leaked via the Bluetooth setsockopt call due to an uninitialised stack buffer. This could be used by local attackers to read the contents of sensitive kernel memory.

This could be used by a local user to DoS a system by consuming all available memory. The PaX Team discovered a potential buffer overflow in the random number generator which may permit local users to cause a denial of service or gain additional privileges. This issue is not believed to effect default Debian installations where only root has sufficient privileges to exploit it. Adam Litke reported a potential local denial of service (oops) on powerpc platforms resulting from unchecked VMA expansion into address space reserved for hugetlb pages. Steve French reported that CIFS filesystems with CAP_UNIX enabled were not honoring a process umask, which may lead to unintentionally relaxed permissions. Wojciech Purczynski discovered that pdeath_signal was not being reset properly under certain conditions, which may allow local users to gain privileges by sending arbitrary signals to suid binaries. Hugh Dickins discovered a potential local DoS (panic) in hugetlbfs. A misconversion of hugetlb_vmtruncate_list to prio_tree may allow local users to trigger a BUG_ON() call in exit_mmap. Alan Cox reported an issue in the aacraid driver that allows unprivileged local users to make ioctl calls which should be restricted to admin privileges. Wojciech Purczynski discovered a vulnerability that can be exploited by a local user to obtain superuser privileges on x86_64 systems. This resulted from improper clearing of the high bits of registers during ia32 system call emulation. This vulnerability is relevant to the Debian amd64 port as well as users of the i386 port who run the amd64 linux-image flavour. Alex Smith discovered an issue with the pwc driver for certain webcam devices. If the device is removed while a userspace application has it open, the driver will wait for userspace to close the device, resulting in a blocked USB subsystem.
