Buffer overflow in the MSN protocol handler for gaim 0.79 to 1.0.1 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via an "unexpected sequence of MSNSLP messages" that results in an unbounded copy operation that writes to the wrong buffer.

Buffer overflow in the AIM and ICQ module in Gaim before 1.5.0 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via an away message with a large number of AIM substitution strings, such as %t or %n.
