Format string vulnerability in the client for Mtp-Target 1.2.2 and earlier allows remote attackers to execute arbitrary code via game messages or other text.

Integer signedness error in certain older versions of the NeL library, as used in Mtp-Target 1.2.2 and earlier, and possibly other products, allows remote attackers to cause a denial of service (memory consumption or server crash) via a negative value in a STLport call, which is not caught by a signed comparison.
