SuSE 11 Security Update : Linux kernel (SAT Patch Numbers 3358 / 3361 / 3362)

High Nessus Plugin ID 50925

Synopsis

The remote SuSE 11 host is missing one or more security updates.

Description

This security update of the SUSE Linux Enterprise 11 GA kernel updates the kernel to 2.6.27.54 and fixes various security issues and other bugs.

The following security issues were fixed :

- Multiple integer signedness errors in net/rose/af_rose.c in the Linux kernel allowed local users to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a rose_getname function call, related to the rose_bind and rose_connect functions. (CVE-2010-3310)

- A kernel information leak via the WEXT ioctl was fixed.
(CVE-2010-2955)

- A double free in an alsa error path was fixed, which could lead to kernel crashes. (CVE-2010-3080)

- Fixed a kernel information leak in the xfs filesystem.
(CVE-2010-3078)

- Fixed a kernel information leak in the cxgb3 driver.
(CVE-2010-3296)

- Fixed a kernel information leak in the net/eql driver.
(CVE-2010-3297)

- The irda_bind function in net/irda/af_irda.c in the Linux kernel did not properly handle failure of the irda_open_tsap function, which allowed local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact via multiple unsuccessful calls to bind on an AF_IRDA (aka PF_IRDA) socket. (CVE-2010-2954)

- The 'os2' xattr namespace on the jfs filesystem could be used to bypass xattr namespace rules. (CVE-2010-2946)

- Fixed a kernel information leak in the net scheduler code. (CVE-2010-2942)

- Integer overflow in the ext4_ext_get_blocks function in fs/ext4/extents.c in the Linux kernel allowed local users to cause a denial of service (BUG and system crash) via a write operation on the last block of a large file, followed by a sync operation.
(CVE-2010-3015)

- The drm_ioctl function in drivers/gpu/drm/drm_drv.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel allowed local users to obtain potentially sensitive information from kernel memory by requesting a large memory-allocation amount. (CVE-2010-2803)

- The gfs2_dirent_find_space function in fs/gfs2/dir.c in the Linux kernel used an incorrect size value in calculations associated with sentinel directory entries, which allowed local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact by renaming a file in a GFS2 filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c. (CVE-2010-2798)

Solution

Apply SAT patch number 3358 / 3361 / 3362 as appropriate.
