critical Nessus Plugin ID 89866

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Markus Vervier discovered that OTR incorrectly handled large incoming messages. A remote attacker could use this issue to cause OTR to crash, resulting in a denial of service, or possibly execute arbitrary code.

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

Solution

Update the affected libotr2 package.
