This update for libotr fixes the following issue :

  • Apply β€˜libotr-CVE-2016-2851.patch’ to fix integer overflows that used to occur on 64-bit architectures when receiving 4GB messages. This flaw could potentially have been exploited by an attacker to remotely execute arbitrary code on the user’s machine

  • (CVE-2016-2851, bsc#969785)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
