Fedora 7 : kernel-2.6.22.1-27.fc7 (2007-1130)

This script is Copyright (C) 2007-2015 Tenable Network Security, Inc.


Synopsis :

The remote Fedora host is missing a security update.

Description :

Rebase kernel to 2.6.22.1:
http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.22
http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.22.1

Includes the CFS scheduler from upstream kernel 2.6.23.

Users should update to the latest autofs package with this kernel or
autofs will use excessive amounts of CPU time.

CVE-2007-3642: The decode_choice function in
net/netfilter/bf_conntrack_h323_asn1.c in the Linux kernel before
2.6.22 allows remote attackers to cause a denial of service (crash)
via an encoded, out-of-range index value for a choice field, which
triggers a NULL pointer dereference.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
