Debian DSA-2627-1 : nginx - information leak

low Nessus Plugin ID 64663
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the nginx packages.

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