Squid contains a bug in the handling of certain DNS responses resulting in a Denial of Service.
|Package||net-proxy/squid on all architectures|
|Affected versions||< 2.5.8|
|Unaffected versions||>= 2.5.8|
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 other features.
Handling of certain DNS responses trigger assertion failures.
By returning a specially crafted DNS response an attacker could cause Squid to crash by triggering an assertion failure.
There is no known workaround at this time.
All Squid users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/squid-2.5.8"
