Gentoo Linux Security Advisory

Title: Squid: Denial of Service through DNS responses (GLSA 200502-25)
Severity: normal
Exploitable: remote
Date: February 18, 2005
Bug(s): #81997
ID: 200502-25

Synopsis


Squid contains a bug in the handling of certain DNS responses 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 other features.


Affected Packages

Package: net-proxy/squid
Vulnerable: < 2.5.8
Unaffected: >= 2.5.8
Architectures: All supported architectures


Description


Handling of certain DNS responses trigger assertion failures.


Impact


By returning a specially crafted DNS response an attacker could
cause Squid to crash by triggering an assertion failure.


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-2.5.8"
