Upgrade Debian:8 libotr to version 4.1.0-2+deb8u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libotr package and not the libotr package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
Integer overflow in proto.c in libotr before 4.1.1 on 64-bit platforms allows remote attackers to cause a denial of service (memory corruption and application crash) or execute arbitrary code via a series of large OTR messages, which triggers a heap-based buffer overflow.
