Description Agostino Sarubbo gentoo-dev 2015-03-13 14:21:07 UTC
From ${URL} :

A TLS impersonation attack was discovered in Mono's TLS stack by
researchers at Inria. During checks on our TLS stack, we have
discovered two further issues which we have fixed - SSLv2 support, and
vulnerability to FREAK. These vulnerabilities affect basically every
Mono version ever released.

All three issues should be addressed in the following patches:

These patches should apply to all Mono versions from 3.4.0 or so
onwards. The EXPORT cipher removal patch requires slight modification
in order to apply to Mono releases prior to 3.x - should work for
these users. The Impersonation patch requires slight modification to
apply to Mono releases prior to 3.4 - should work for
these users.

Alternatively, this is fixed in Mono 3.12.1 and higher:

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

CVE-2015-2318 is

CVE-2015-2320 is

CVE-2015-2320 is

This is fixed at least for 4.4.x but our 2.10.x is still vulnerable.

@ Maintainer(s): Please tell us if you are going to patch 2.10.x or want to remove/mask instead.
