CVE-2016-2851

Name of the Vulnerable Software and Affected Versions libotr versions prior to 4.1.1

Description The issue is caused by an integer overflow in the proto.c file of libotr, which can lead to memory corruption and application crash, or potentially allow execution of arbitrary code. This occurs when a series of large OTR messages are sent, triggering a heap-based buffer overflow. The issue is specific to 64-bit platforms.

Recommendations For versions prior to 4.1.1, update to version 4.1.1 or later to resolve the issue. As a temporary workaround, consider restricting the size of OTR messages to prevent the overflow.
