TITLE

Gopher of gopherToHTML Buffer overflow vulnerability in functions

DESCRIPTION

Buffer overflow in the gopherToHTML function in gopher.cc in the Gopher reply parser in Squid 3.0 before 3.0.STABLE26, 3.1 before 3.1.15, and 3.2 before 3.2.0.11 allows remote Gopher servers to cause a denial of service (memory corruption and daemon restart) or possibly have unspecified other impact via a long line in a response. NOTE: This issue exists because of a CVE-2005-0094 regression. Squid is a proxy server and web cache server. Squid is flawed in parsing responses from the Gopher server. If the Gopher server returns more than 4096 bytes, it can trigger a buffer overflow. This overflow can cause memory corruption to generally cause Squid to crash. A malicious user must set up a fake Gopher server and forward the request through Squid. Successful exploitation of vulnerabilities allows arbitrary code to be executed in a server context. Squid Proxy is prone remote buffer-overflow vulnerability affects the Gopher-to-HTML functionality. Failed exploit attempts will result in a denial-of-service condition. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA-2304-1 security@debian.org http://www.debian.org/security/ Nico Golde Sep 11, 2011 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : squid3 Vulnerability : buffer overflow Problem type : remote Debian-specific: no Debian bug : 639755 CVE IDs : CVE-2011-3205 Ben Hawkes discovered that squid3, a full featured Web Proxy cache (HTTP proxy), is vulnerable to a buffer overflow when processing gopher server replies.
