Ubuntu 9.04 / 9.10 / 10.04 LTS : libpam-opie vulnerability (USN-955-2)

High Nessus Plugin ID 47111


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


USN-955-1 fixed vulnerabilities in OPIE. This update provides rebuilt libpam-opie packages against the updated libopie library.

Maksymilian Arciemowicz and Adam Zabrocki discovered that OPIE incorrectly handled long usernames. A remote attacker could exploit this with a crafted username and make applications linked against libopie crash, leading to a denial of service.

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 libpam-opie package.
