Ubuntu 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : libotr vulnerability (USN-1541-1)

Medium Nessus Plugin ID 61570


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


Justin Ferguson discovered multiple heap overflows in libotr. A remote attacker could use this to craft a malformed OTR message that could cause a denial of service via application crash 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.


Update the affected libotr2 package.
