CVE-2011-5054: Kde Kcheckpass

Medium severity, CVSS 6.9. EPSS: 0.3% chance of exploitation in the next 30 days.

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."
