Synopsis

Squid contains several bugs when handling certain malformed requests resulting in a Denial of Service.

Background

Squid is a full-featured Web proxy cache designed to run on Unix-like systems. It supports proxying and caching of HTTP, FTP, and other protocols, as well as SSL support, cache hierarchies, transparent caching, access control lists and many more features.

Affected Packages

Package: net-proxy/squid

Unaffected: >= 2.5.10-r2
Architectures: All supported architectures

Workaround
