Package        : mono
CVE ID         : CVE-2015-2318 CVE-2015-2319 CVE-2015-2320
Debian Bug     : 780751

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).

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

For the unstable distribution (sid), these problems have been fixed in
version 3.2.8+dfsg-10.

We recommend that you upgrade your mono packages.
