Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200711-10
(Mono: Buffer overflow)

IOActive discovered an error in the Mono.Math.BigInteger class, in the
reduction step of the Montgomery-based Pow methods, that could lead to
a buffer overflow.

Impact :

A remote attacker could exploit this vulnerability by sending specially
crafted data to Mono applications using the BigInteger class, which
might lead to the execution of arbitrary code with the privileges of
the user running the application (possibly root) or a Denial of
Service.

Workaround :

There is no known workaround at this time.
