Debian DSA-3202-1 : mono - security update

critical Nessus Plugin ID 82000

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Researchers at INRIA and Xamarin discovered several vulnerabilities in mono, a platform for running and developing applications based on the ECMA/ISO Standards. Mono's TLS stack contained several problems that hampered its capabilities: those issues could lead to client impersonation (via SKIP-TLS), SSLv2 fallback, and encryption weakening (via FREAK).

Solution

Upgrade the mono packages.

For the stable distribution (wheezy), these problems have been fixed in version 2.10.8.1-8+deb7u1.
