Oracle Linux 5 : Unbreakable Enterprise kernel (ELSA-2010-2008)

High Nessus Plugin ID 68172


The remote Oracle Linux host is missing one or more security updates.


Description of changes:

Following security fixes are included in this unbreakable enterprise kernel errata:

CVE-2010-2942 The actions implementation in the network queueing functionality in the Linux kernel before 2.6.36-rc2 does not properly initialize certain structure members when performing dump operations, which allows local users to obtain potentially sensitive information from kernel memory via vectors related to (1) the tcf_gact_dump function in net/sched/act_gact.c, (2) the tcf_mirred_dump function in net/sched/act_mirred.c, (3) the tcf_nat_dump function in net/sched/act_nat.c, (4) the tcf_simp_dump function in net/sched/act_simple.c, and (5) the tcf_skbedit_dump function in net/sched/act_skbedit.c.

CVE-2010-2943 The xfs implementation in the Linux kernel before 2.6.35 does not look up inode allocation btrees before reading inode buffers, which allows remote authenticated users to read unlinked files, or read or overwrite disk blocks that are currently assigned to an active file but were previously assigned to an unlinked file, by accessing a stale NFS file handle.

OCFS2 Fix to prevent kernel panic caused by corrupted fast symlinks in ocfs2 filesystem.

- [fs] xfs: return inode fork offset in bulkstat for fsr (Dave Chinner)
- [fs] xfs: always use iget in bulkstat (Dave Chinner) {CVE-2010-2943}
- [fs] xfs: validate untrusted inode numbers during lookup (Dave Chinner) {CVE-2010-2943}
- [fs] xfs: rename XFS_IGET_BULKSTAT to XFS_IGET_UNTRUSTED (Dave Chinner) {CVE-2010-2943}
- [net] net sched: fix some kernel memory leaks (Eric Dumazet) {CVE-2010-2942}
- [fs] ocfs2: Don't walk off the end of fast symlinks (Joel Becker)
