DSA-2627-1 nginx -- information leak

Date Reported:

17 Feb 2013

Affected Packages:

nginx

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 700426.
In Mitre's CVE dictionary: CVE-2012-4929.

More information:

Juliano Rizzo and Thai Duong discovered a weakness in the TLS/SSL protocol when using compression. This side channel attack, dubbed CRIME, allows eavesdroppers to gather information to recover the original plaintext in the protocol. This update to nginx disables SSL compression.

For the stable distribution (squeeze), this problem has been fixed in version 0.7.67-3+squeeze3.

For the testing distribution (wheezy), and unstable distribution (sid), this problem has been fixed in version 1.1.16-1.

We recommend that you upgrade your nginx packages.
