Detail
Problem Description: Updated kernel packages that resolve several security issues are now available for Red Hat Enterprise Linux 5.2 Extended Update Support. 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 (v. 5.2.z server) - i386, ia64, noarch, ppc, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. This update includes backported fixes for four security issues. These issues only affected users of Red Hat Enterprise Linux 5.2 Extended Update Support as they have already been addressed for users of Red Hat Enterprise Linux 5 in the 5.3 update, RHSA-2009:0225. In accordance with the support policy, future security updates to Red Hat Enterprise Linux 5.2 Extended Update Support will only include issues of critical security impact. * when fput() was called to close a socket, the __scm_destroy() function in the Linux kernel could make indirect recursive calls to itself. This could, potentially, lead to a denial of service issue. (CVE-2008-5029, Important) * the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important) * a flaw was found in the Asynchronous Transfer Mode (ATM) subsystem. A local, unprivileged user could use the flaw to listen on the same socket more than once, possibly causing a denial of service. (CVE-2008-5079, Important) * a race condition was found in the Linux kernel "inotify" watch removal and umount implementation. This could allow a local, unprivileged user to cause a privilege escalation or a denial of service. (CVE-2008-5182, Important) Users should upgrade to these updated packages, which contain backported patches to correct these issues. Note: for this update to take effect, the system must be rebooted. 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/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 470201 - CVE-2008-5029 kernel: Unix sockets kernel panic 472325 - CVE-2008-5182 kernel: fix inotify watch removal/umount races 473259 - CVE-2008-5300 kernel: fix soft lockups/OOM issues with unix socket garbage collector 473696 - CVE-2008-5079 Linux Kernel 'atm module' Local Denial of Service |

Title: | DSA-1681 linux-2.6.24 -- denial of service/privilege escalation | ||
Description: | Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems: Eugene Teo reported a local DoS issue in the ext2 and ext3 filesystems. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a corrupted filesystem that causes the kernel to output error messages in an infinite loop. Milos Szeredi reported that the usage of splice() on files opened with O_APPEND allows users to write to the file at arbitrary offsets, enabling a bypass of possible assumed semantics of the O_APPEND flag. Vlad Yasevich reported an issue in the SCTP subsystem that may allow remote users to cause a local DoS by triggering a kernel oops. Wei Yongjun reported an issue in the SCTP subsystem that may allow remote users to cause a local DoS by triggering a kernel panic. Eric Sesterhenn reported a local DoS issue in the hfsplus filesystem. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a corrupted filesystem that causes the kernel to overrun a buffer, resulting in a system oops or memory corruption. Eric Sesterhenn reported a local DoS issue in the hfsplus filesystem. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a corrupted filesystem that results in a kernel oops due to an unchecked return value. Eric Sesterhenn reported a local DoS issue in the hfs filesystem. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a filesystem with a corrupted catalog name length, resulting in a system oops or memory corruption. Andrea Bittau reported a DoS issue in the unix socket subsystem that allows a local user to cause memory corruption, resulting in a kernel panic. Johannes Berg reported a remote DoS issue in the libertas wireless driver, which can be triggered by a specially crafted beacon/probe response. Al Viro reported race conditions in the inotify subsystem that may allow local users to acquire elevated privileges. Dann Frazier reported a DoS condition that allows local users to cause the out of memory handler to kill off privileged processes or trigger soft lockups due to a starvation issue in the unix socket subsystem. | ||
