1.88.5. RHSA-2009:1548: Important security and bug fix update
Important
This update has already been released (prior to the GA of this release) as the security
errata
RHSA-2009:1548
649
Updated kernel packages that fix multiple security issues and several bugs are now available for Red
Hat Enterprise Linux 5.
This update has been rated as having important security impact by the Red Hat Security Response
Team.
The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security fixes:
* a system with SELinux enforced was more permissive in allowing local users in the unconfined_t
domain to map low memory areas even if the mmap_min_addr restriction was enabled. This could aid
in the local exploitation of NULL pointer dereference bugs. (
CVE-2009-2695
650
, Important)
* a NULL pointer dereference flaw was found in the eCryptfs implementation in the Linux kernel.
A local attacker could use this flaw to cause a local denial of service or escalate their privileges.
(
CVE-2009-2908
651
, Important)
* a flaw was found in the NFSv4 implementation. The kernel would do an unnecessary permission
check after creating a file. This check would usually fail and leave the file with the permission bits set
to random values. Note: This is a server-side only issue. (
CVE-2009-3286
