Ubuntu 10.04 LTS / 12.04 LTS / 12.10 / 13.10 : freeradius vulnerabilities (USN-2122-1)
High Nessus Plugin ID 72719
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt was discovered that FreeRADIUS incorrectly handled unix authentication. A remote user could successfully authenticate with an expired password. (CVE-2011-4966)
Pierre Carrier discovered that FreeRADIUS incorrectly handled rlm_pap hash processing. An authenticated user could use this issue to cause FreeRADIUS to crash, resulting in a denial of service, or possibly execute arbitrary code. The default compiler options for affected releases should reduce the vulnerability 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.
SolutionUpdate the affected freeradius package.
