Mandriva Linux Security Advisory MDVSA-2009:293-1
http://www.mandriva.com/security/
_______________________________________________________________________

Package : squidGuard
Date : January 11, 2010
Affected: 2008.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been found and corrected in squidGuard:

Buffer overflow in sgLog.c in squidGuard 1.3 and 1.4 allows remote
attackers to cause a denial of service (application hang or loss of
blocking functionality) via a long URL with many / (slash) characters,
related to emergency mode. (CVE-2009-3700).

Multiple buffer overflows in squidGuard 1.4 allow remote attackers
to bypass intended URL blocking via a long URL, related to (1)
the relationship between a certain buffer size in squidGuard and a
certain buffer size in Squid and (2) a redirect URL that contains
information about the originally requested URL (CVE-2009-3826).

squidGuard was upgraded to 1.2.1 for MNF2/CS3/CS4 with additional
upstream security and bug fixes patches applied.

This update fixes these vulnerabilities.

Update:

Packages for 2008.0 are provided for Corporate Desktop 2008.0
customers.
