high Nessus Plugin ID 27827

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.

Solution

All Mono users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/mono-1.2.5.1-r1'
