From: secure@conectiva.com.br To: conectiva-updates@papaleguas.conectiva.com.br, linuxlist@securityportal.com, lwn@lwn.net, bugtraq@securityfocus.com, security-alerts@linuxsecurity.com Subject: [CLA-2001:426] Conectiva Linux Security Announcement - squid Date: Wed, 26 Sep 2001 16:12:38 -0300 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : squid SUMMARY : Squid multiple vulnerabilities DATE : 2001-09-26 16:11:00 ID : CLA-2001:426 RELEVANT RELEASES : 4.0, 4.0es, 4.1, 4.2, 5.0, prg graficos, ecommerce, 5.1, 6.0, 7.0 - ------------------------------------------------------------------------- DESCRIPTION Squid is a caching/proxy daemon for HTTP/FTP/Gopher. This update fixes two vulnerabilities: 1. Vladimir Ivaschenko found a bug[1] which allows a remote attacker to cause a DoS on the squid proxy service by sending mkdir ftp requests. 2. Takashi Taniguchi found a bug[2] that allows malicious users to do portscanning and other suspect activities using the proxy when it's configured in "http accelerator mode". Also, this update improves the squid script service handling (start/stop/restart/reload) and removes the suid bit from the PAM squid auth module on CL 7.0. Note: Conectiva Linux 7.0 is not affected by bug #2. REFERENCES: 1. http://www.squid-cache.org/bugs/show_bug.cgi?id=233 2. http://www.squid-cache.org/Versions/v2/2.3/bugs/#squid-2.3.stable4-accel_only_access 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.
