Package        : squid
Vulnerability  : programming error
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2007-6239

It was discovered that malformed cache update replies against the Squid
WWW proxy cache could lead to the exhaustion of system memory, resulting
in potential denial of service.

For the stable distribution (etch), this problem has been fixed in
version 2.6.5-6etch1.

For the old stable distribution (sarge), the update cannot currently
be processed on the buildd security network due to a bug in the archive
management script. This will be resolved soon. An update for i386
is temporarily available at at

We recommend that you upgrade your squid packages.
