Debian DSA-465-1 : openssl - several vulnerabilities

medium Nessus Plugin ID 15302
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

Two vulnerabilities were discovered in openssl, an implementation of the SSL protocol, using the Codenomicon TLS Test Tool. More information can be found in the following NISCC Vulnerability Advisory and this OpenSSL advisory. The Common Vulnerabilities and Exposures project identified the following vulnerabilities :

- CAN-2004-0079 NULL pointer assignment in the do_change_cipher_spec() function. A remote attacker could perform a carefully crafted SSL/TLS handshake against a server that used the OpenSSL library in such a way as to cause OpenSSL to crash. Depending on the application this could lead to a denial of service.

- CAN-2004-0081

A bug in older versions of OpenSSL 0.9.6 that can lead to a Denial of Service attack (infinite loop).

Solution

For the stable distribution (woody) these problems have been fixed in openssl version 0.9.6c-2.woody.6, openssl094 version 0.9.4-6.woody.4 and openssl095 version 0.9.5a-6.woody.5.

We recommend that you update your openssl package.
