Gentoo Linux Security Advisory

Title: Squid: Denial of Service vulnerabilities (GLSA 200509-06)
Severity: normal
Exploitable: remote
Date: September 07, 2005
Updated: May 22, 2006
Bug(s): #104603
ID: 200509-06

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
assertion failures.


Impact


By performing malformed requests an attacker could cause Squid to crash
by triggering an assertion failure or invalid memory reference.


Workaround


There is no known workaround at this time.


Resolution


All Squid users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=net-proxy/squid-2.5.10-r2"
