Package : squid
Vulnerability : design flaw
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2005-1345
Debian Bug : 307132

Michael Bhola discovered a bug in Squid, the popular WWW proxy cache.
Squid does not trigger a fatal error when it identifies missing or
invalid ACLs in the http_access configuration, which could lead to
less restrictive ACLs than intended by the administrator.

For the stable distribution (woody) this problem has been fixed in
version 2.4.6-2woody8.

For the unstable distribution (sid) this problem has been fixed in
version 2.5.9-7.

We recommend that you upgrade your squid packages.
