USN-2422-1: Squid vulnerabilities

25 November 2014

Squid could be made to crash if it received specially crafted network traffic.



  • squid3 - Web proxy cache server


Sebastian Krahmer discovered that the Squid pinger incorrectly handled
certain malformed ICMP packets. A remote attacker could possibly use this
issue to cause Squid to crash, resulting in a denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.10
Ubuntu 14.04

In general, a standard system update will make all the necessary changes.
