Debian Security Advisory

DSA-1991-1 squid/squid3 -- denial of service

Date Reported:

04 Feb 2010

Affected Packages:

squid/squid3

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 534982.
In Mitre's CVE dictionary: CVE-2009-2855, CVE-2010-0308.

More information:

Two denial of service vulnerabilities have been discovered in squid and squid3, a web proxy. The Common Vulnerabilities and Exposures project identifies the following problems:

• CVE-2009-2855

  Bastian Blank discovered that it is possible to cause a denial of service via a crafted auth header with certain comma delimiters.

• CVE-2010-0308

  Tomas Hoger discovered that it is possible to cause a denial of service via invalid DNS header-only packets.

For the stable distribution (lenny), these problems have been fixed in version 2.7.STABLE3-4.1lenny1 of the squid package and version 3.0.STABLE8-3+lenny3 of the squid3 package.

For the oldstable distribution (etch), these problems have been fixed in version 2.6.5-6etch5 of the squid package and version 3.0.PRE5-5+etch4 of the squid3 package.

For the testing distribution (squeeze) and the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your squid/squid3 packages.

Fixed in:

Debian GNU/Linux 4.0 (etch)
