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.

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.
