Description:
A vulnerability and a weakness have been reported in Gaim, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a user's system.
1) A boundary error within the processing of messages containing URLs can be exploited to cause a stack-based buffer overflow via a message containing an overly long URL (more than 8192 bytes).
Successful exploitation allows execution of arbitrary code.
2) A NULL pointer dereference error within the handling of MSN messages can be exploited to crash the application via a SLP message with an empty body.
Solution:
Update to version 1.3.0.
