Mandriva Linux Security Advisory : squidGuard (MDVSA-2009:293-1)

Medium Nessus Plugin ID 42356


The remote Mandriva Linux host is missing a security update.


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.
