medium Nessus Plugin ID 36090
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

It was discovered that insufficient length validations in the ASN.1 handling of the OpenSSL crypto library may lead to denial of service when processing a manipulated certificate.

Solution

Upgrade the openssl packages.

For the old stable distribution (etch), this problem has been fixed in version 0.9.8c-4etch5 of the openssl package and in version 0.9.7k-3.1etch3 of the openssl097 package.

For the stable distribution (lenny), this problem has been fixed in version 0.9.8g-15+lenny1.
