CVE-2016-2367: Canonical Ubuntu Linux

Medium severity, CVSS 5.9. EPSS: 1.9% chance of exploitation in the next 30 days.

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.

Affected products

• Canonical Ubuntu Linux: version 12.04 only; version 14.04 only; version 15.10 only
• Debian Debian Linux: version 8.0 only
• Pidgin Pidgin: up to and including 2.10.12
