Gaim-Encryption 2.38-1 on Debian Linux allows remote attackers to cause a denial of service (crash) via a crafted message from an ICQ buddy, possibly involving the GE_received_key function in keys.c.

decrypt_msg for the Gaim-Encryption GAIM plugin 1.15 and earlier does not properly validate a message length parameter, which allows remote attackers to cause a denial of service (crash) via a negative length, which overwrites arbitrary heap memory with a zero byte.
