DESCRIPTION:
A vulnerability has been reported in Pidgin, which can be exploited
by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error within the
"mxit_show_message()" function (libpurple/protocols/mxit/markup.c)
when parsing incoming messages containing inline images. This can be
exploited to cause a stack-based buffer overflow via a specially
crafted RX message.

Successful exploitation of the vulnerability may allow execution of
arbitrary code.

The vulnerability is reported in versions prior to 2.10.5.

SOLUTION:
Update to version 2.10.5.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Ulf Härnhammar.
