An information leak exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent via the server could potentially result in an out-of-bounds read. A malicious user, server, or man-in-the-middle can send an invalid size for an avatar which will trigger an out-of-bounds read vulnerability. This could result in a denial of service or copy data from memory to the file, resulting in an information leak if the avatar is sent to another user.

CVE-2016-2365 Pidgin vulnerabilities
Title: Pidgin vulnerabilities
Summary: Pidgin could be made to crash or run programs if it received
specially crafted network traffic.
Yves Younan discovered that Pidgin contained multiple issues in the MXit
protocol support. A remote attacker could use this issue to cause Pidgin to
crash, resulting in a denial of service, or possibly execute arbitrary
code.
Instructions: After a standard system update you need to restart Pidgin to make all the
necessary changes.
