Discussion

Pidgin MSN Use-After-Free Denial of Service Vulnerability

Successful exploits will cause the affected application to crash, effectively denying service to legitimate users. Due to the nature of this issue, remote code execution may be possible; this has not been confirmed.

Versions prior to Pidgin 2.7.6 are vulnerable.
