|Gentoo Linux Security Advisory
Title: Squid: NTLM authentication helper buffer overflow (GLSA 200406-13)
Date: June 17, 2004
Updated: September 02, 2004
Squid contains a bug where it fails to properly check bounds of the 'pass'
Squid contains a bug in the function ntlm_check_auth(). It fails to do
proper bounds checking on the values copyied to the 'pass' variable.
Vulnerable: <= 2.5.5-r1
Unaffected: >= 2.5.5-r2
Architectures: All supported architectures
Squid is a full-featured Web Proxy Cache designed to run on Unix systems.
It supports proxying and caching of HTTP, FTP, and other URLs, as well as
SSL support, cache hierarchies, transparent caching, access control lists
and many other features.
If Squid is configured to use NTLM authentication, an attacker could
exploit this vulnerability by sending a very long password. This could lead
to arbitrary code execution with the permissions of the user running Squid.
There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version.
All Squid users should upgrade to the latest stable version:
|# emerge sync
# emerge -pv ">=net-proxy/squid-2.5.5-r2"
# emerge ">=net-proxy/squid-2.5.5-r2"
