Package : squid
Vulnerability : buffer overflow, integer overflow
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2005-0094 CAN-2005-0095

Several vulnerabilities have been discovered in Squid, the internet object cache, the popular WWW proxy cache. The Common Vulnerabilities and Exposures Project identifies the following vulnerabilities:

CAN-2005-0094

"infamous41md" discovered a buffer overflow in the parser for Gopher responses which will lead to memory corruption and usually crash Squid.

CAN-2005-0095

"infamous41md" discovered an integer overflow in the receiver of WCCP (Web Cache Communication Protocol) messages. An attacker could send a specially crafted UDP datagram that will cause Squid to crash.

For the stable distribution (woody) these problems have been fixed in version 2.4.6-2woody5.

For the unstable distribution (sid) these problems have been fixed in version 2.5.7-4.

We recommend that you upgrade your squid package.
