CentOS Update for kernel CESA-2010:0723 centos5 i386

The remote host is missing an update for the 'kernel' package(s) announced via the referenced advisory.

The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * A buffer overflow flaw was found in the ecryptfs_uid_hash() function in the Linux kernel eCryptfs implementation. On systems that have the eCryptfs netlink transport (Red Hat Enterprise Linux 5 does) or where the &'/dev/ecryptfs' file has world writable permissions (which it does not, by default, on Red Hat Enterprise Linux 5), a local, unprivileged user could use this flaw to cause a denial of service or possibly escalate their privileges. (CVE-2010-2492, Important) * A miscalculation of the size of the free space of the initial directory entry in a directory leaf block was found in the Linux kernel Global File System 2 (GFS2) implementation. A local, unprivileged user with write access to a GFS2-mounted file system could perform a rename operation on that file system to trigger a NULL pointer dereference, possibly resulting in a denial of service or privilege escalation. (CVE-2010-2798, Important) * A flaw was found in the Xen hypervisor implementation when running a system that has an Intel CPU without Extended Page Tables (EPT) support. While attempting to dump information about a crashing fully-virtualized guest, the flaw could cause the hypervisor to crash the host as well. A user with permissions to configure a fully-virtualized guest system could use this flaw to crash the host. (CVE-2010-2938, Moderate) * Information leak flaws were found in the Linux kernel's Traffic Control Unit implementation. A local attacker could use these flaws to cause the kernel to leak kernel memory to user-space, possibly leading to the disclosure of sensitive information. (CVE-2010-2942, Moderate) * A flaw was found in the Linux kernel's XFS file system implementation. The file handle lookup could return an invalid inode as valid. If an XFS file system was mounted via NFS (Network File System), a local attacker could access stale data or overwrite existing data that reused the inodes. (CVE-2010-2943, Moderate) * An integer overflow flaw was found in the extent range checking code in the Linux kernel's ext4 file system implementation. A local, unprivileged user with write access to an ext4-mounted file system could trigger this flaw by writing to a file at a very large file offset, resulting in a local denial of service. (CVE-2010-3015, Moderate) * An information leak flaw was found in the Linux kernel's USB implementation. Certain USB errors could result in an uninitia ...
