Debian DSA-2998-1 : openssl - security update

high Nessus Plugin ID 77035
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

Multiple vulnerabilities have been identified in OpenSSL, a Secure Sockets Layer toolkit, that may result in denial of service (application crash, large memory consumption), information leak, protocol downgrade. Additionally, a buffer overrun affecting only applications explicitly set up for SRP has been fixed (CVE-2014-3512 ).

Detailed descriptions of the vulnerabilities can be found at:
www.openssl.org/news/secadv/20140806.txt

It's important that you upgrade the libssl1.0.0 package and not just the openssl package.

All applications linked to openssl need to be restarted. You can use the 'checkrestart' tool from the debian-goodies package to detect affected programs. Alternatively, you may reboot your system.

Solution

Upgrade the openssl packages.

For the stable distribution (wheezy), these problems have been fixed in version 1.0.1e-2+deb7u12.
