Detail
| Problem Description: Updated kernel packages that fix a number of security issues as well as other bugs are now available for Red Hat Enterprise Linux 2.1 (32 bit architectures) This security advisory has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386 Red Hat Linux Advanced Workstation 2.1 - Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 3. Problem description: The Linux kernel handles the basic functions of the operating system. These new kernel packages contain fixes for the security issues described below: * a flaw in the USB devio handling of device removal that allowed a local user to cause a denial of service (crash) (CVE-2005-3055, moderate) * a flaw in ROSE due to missing verification of the ndigis argument of new routes (CVE-2005-3273, moderate) * an info leak on AMD-based x86 systems that allowed a local user to retrieve the floating point exception state of a process run by a different user (CVE-2006-1056, important) * a minor info leak in socket name handling in the network code (CVE-2006-1342, low) * a minor info leak in socket option handling in the network code (CVE-2006-1343, low) * a directory traversal vulnerability in smbfs that allowed a local user to escape chroot restrictions for an SMB-mounted filesystem via "..\\" sequences (CVE-2006-1864, moderate) * a flaw in the mprotect system call that allowed to give write permission to a readonly attachment of shared memory (CVE-2006-2071, moderate) A performance bug in the NFS implementation that caused clients to frequently pause when sending TCP segments during heavy write loads was also addressed. All Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels to these updated packages, which contain backported fixes to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. Bug IDs fixed (http://bugzilla.redhat.com/): 155362 - CVE-2005-3273 ROSE ndigis verification 169262 - CVE-2005-3055 async usb devio oops 186245 - CVE-2006-1342 Small information leak in SO_ORIGINAL_DST and getname() (CVE-2006-1343) 189344 - CVE-2006-1056 FPU Information leak on i386/x86-64 on AMD CPUs 189438 - CVE-2006-1864 smbfs chroot issue 190076 - CVE-2006-2071 mprotect gives write permission to a readonly attachment |

| 29841 | Linux Kernel net/ipv4/netfilter/ IPv4 Socket Name Return Arbitrary Memory Dis... The Linux kernel contains a flaw that may lead to local memory disclosure. The issue is due to net/ipv4/netfilter/ip_conntrack_core.c, net/ipv4/netfilter/nf_conntrack_l3proto_ipv4.c and net/ipv4/af_inet.c not properly clearing the 'sockaddr_in.sin_zero' struct. The resulting 6 byte leak to userspace occurs when returning IPv4 socket names from getsockopt(), getpeername(), accept() and getsockname() functions. This could allow a local attacker to possibly obtain sensitive information. |
| 25139 | Linux Kernel mprotect() Function Memory Manipulation |
| 25067 | Linux Kernel SMBFS SMB Mount Traversal chroot Restriction Bypass The Linux Kernel contains a flaw that may allow a malicious user to escape a chroot environment. The issue is triggered when a user attempts to change to a working directory outside a chroot environment in a SMBFS file system using a double backslash, e.g. 'cd ..\\'. It is possible that the flaw may allow unauthorised access to file system resources, resulting in a loss of confidentiality and/or integrity. |
| 24807 | Linux Kernel x87 Register Information Disclosure The Linux kernel contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered because the Floating Point Units (FPUs) of the affected processor types do not save and restore the FOP, FID and FPD registers when certain instructions are executed. As a result, Linux does not clear these registers either. When a context switch occurs, a user can potentially read these uncleared registers which could disclose floating point information, resulting in a loss of confidentiality. |
| 24746 | FreeBSD FPU x87 Register Information Disclosure FreeBSD contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered because the Floating Point Units (FPUs) of the affected processor types do not save and restore the FOP, FID and FPD registers when certain instructions are executed. As a result, FreeBSD does not clear these registers either. When a context switch occurs, a user can potentially read these uncleared registers which could disclose floating point information, resulting in a loss of confidentiality. |
