Overview

CVE-2011-5054 is a medium-severity vulnerability affecting kde kcheckpass. It was published on January 6, 2012 and has a CVSS 2.0 base score of 6.9 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 6.9, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

kcheckpass passes a user-supplied argument to the pam_start function, often within a setuid environment, which allows local users to invoke any configured PAM stack, and possibly trigger unintended side effects, via an arbitrary valid PAM service name, a different vulnerability than CVE-2011-4122. NOTE: the vendor indicates that the possibility of resultant privilege escalation may be "a bit far-fetched."

Remediation

Check the references section for vendor advisories and patches from kde. Update kcheckpass to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
