Debian DSA-2392-1 : openssl - out-of-bounds read

medium Nessus Plugin ID 57643
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

Antonio Martin discovered a denial-of-service vulnerability in OpenSSL, an implementation of TLS and related protocols. A malicious client can cause the DTLS server implementation to crash. Regular, TCP-based TLS is not affected by this issue.

Solution

Upgrade the openssl packages.

For the oldstable distribution (lenny), this problem has been fixed in version 0.9.8g-15+lenny16.

For the stable distribution (squeeze), this problem has been fixed in version 0.9.8o-4squeeze7.
