-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : squid SUMMARY : Multiple vulnerabilities DATE : 2002-02-27 12:27:00 ID : CLA-2002:464 RELEVANT RELEASES : 5.0, prg graficos, ecommerce, 5.1, 6.0, 7.0 - ------------------------------------------------------------------------- DESCRIPTION Squid is a high-performance proxy caching server. Three security issues[1] have recently been found in the Squid-2.X releases up to and including 2.4.STABLE3. From the Squid v2.4 patches page[2]: - Coredump on certain ftp:// style URL's[3] If certain constructed ftp:// style URL's are received then squid crashes, causing a denial of service (DoS) and maybe even remote execution of code. - SNMP memory leaks[4] The SNMP implementation in Squid had several memory leaks possibly causing a denial of service (DoS). - Failure to disable the HTCP port[5] "htcp_port 0" fails to completely disable the HTCP port as documented in squid.conf, instead HTCP will be listening on a random port number. Aditionally, the following patches from the site were applied: - Potential coredump on snmpwalk[6] Fixes a coredump on snmpwalk in certain configurations. - CONNECT/ssl core dump[7] Squid crashes on CONNECT requests that are allowed by http_access but denied by miss_access. - Filedescriptor leakage in the aufs store[8] Fixes a filedescriptor leakage in the "aufs" cache_dir store implementation. SOLUTION It is recommended that all squid users upgrade to the latest packages. This update will automatically restart the service if it is already running.
