Title: Squid: Denial of Service vulnerabilities (GLSA 200509-06)
Date: September 07, 2005
Updated: May 22, 2006
Squid contains several bugs when handling certain malformed requests resulting in a Denial of Service.
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.
Vulnerable: < 2.5.10-r2
Unaffected: >= 2.5.10-r2
Architectures: All supported architectures
Certain malformed requests result in a segmentation fault in the sslConnectTimeout function, handling of other certain requests trigger assertion failures.
By performing malformed requests an attacker could cause Squid to crash by triggering an assertion failure or invalid memory reference.
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-2.5.10-r2"
