Debian DSA-1379-1 : openssl - off-by-one error/buffer overflow

critical Nessus Plugin ID 26209
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

An off-by-one error has been identified in the SSL_get_shared_ciphers() routine in the libssl library from OpenSSL, an implementation of Secure Socket Layer cryptographic libraries and utilities. This error could allow an attacker to crash an application making use of OpenSSL's libssl library, or potentially execute arbitrary code in the security context of the user running such an application.

Solution

Upgrade the openssl packages.

For the old stable distribution (sarge), this problem has been fixed in version 0.9.7e-3sarge5.

For the stable distribution (etch), this problem has been fixed in version 0.9.8c-4etch1.

For the unstable and testing distributions (sid and lenny, respectively), this problem has been fixed in version 0.9.8e-9.
