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


Description


Certain malformed requests result in a segmentation fault in the
sslConnectTimeout function, handling of other certain requests trigger

Workaround

Resolution


All Squid users should upgrade to the latest version:
