DESCRIPTION:
Two weaknesses and a security issue have been reported in Pidgin,
which can be exploited by malicious people to cause a DoS (Denial of
Service) and compromise a user's system.
1) An error within the IRC protocol plugin when handling WHO
responses with certain characters in the nickname can be exploited to
cause a NULL pointer dereference.
2) An error within the MSN protocol plugin when parsing HTTP 100
responses can be exploited to crash the application.
Successful exploitation of this weakness requires that the HTTP
connection method is enabled (disabled by default) and that a
malicious server is used.
3) The application executes "file://" URIs when clicked, which can be
exploited by e.g. tricking a user into clicking a "file://" URI
pointing to a malicious executable on a remote network share.
Note: This security issue affects the Windows platform only.
SOLUTION:
Update to version 2.10.0.
