CVE 2010-4254

Mono, when Moonlight before 2.3.0.1 or 2.99.x before 2.99.0.10 is used, does not properly validate arguments to generic methods, which allows remote attackers to bypass generic constraints, and possibly execute arbitrary code, via a crafted method call.

See the CVE page on Mitre.org for more details.
