Mandriva Linux Security Update Advisory
_______________________________________________________________________

Package name: kernel
Advisory ID: MDKSA-2005:171
Date: October 3rd, 2005

Affected versions: Corporate 3.0, Multi Network Firewall 2.0
______________________________________________________________________

Problem Description:

A number of vulnerabilities in the 2.6 Linux kernel have been corrected
with these updated packages:

An array index overflow in the xfrm_sk_policy_insert function could
allow a local user to cause a Denial of Service (oops or deadlock) and
possibly execute arbitrary code (CAN-2005-2456).

The zlib routines in the Linux 2.6 kernel before 2.6.12.5 allowed a
remote attacker to cause a DoS (crash) via a compressed file with
"improper tables" (CAN-2005-2458).

The huft_build function in the zlib routines in Linux 2.6 kernels prior
to 2.6.12.5 returned the wrong value, allowing remote attackers to
cause a DoS (crash) via a certain compressed file (CAN-2005-2459).

A stack-based buffer overflow in the sendmsg function call in Linux 2.6
kernels prior to 2.6.13.1 allow local users to execute arbitrary code by
calling sendmsg and modifying the message contents in another thread
(CAN-2005-2490).

xattr.c in the ext2 and ext3 file system code in the 2.6 Linux kernel
did not properly compare the name_index fields when sharing xattr
blocks which would prevent default ACLs from being applied
(CAN-2005-2801).

The ipt_recent kernel module in 2.6 Linux kernels prior to 2.6.12 when
running on 64-bit processors allowed remote attackers to cause a DoS
(kernel panic) via certain attacks such as SSH brute force
(CAN-2005-2872).

The ipt_recent kernel module in 2.6 Linux kernels prior to 2.6.12 did
not properly perform certain time tests when the jiffies value is
greater than LONG_MAX which could cause ipt_recent netfilter rules to
block too early (CAN-2005-2873).

The updated packages have been patched to address these issues and all
users are urged to upgrade immediately.

Updated kernels for Mandrivalinux 10.1 and later will be made available
soon.
