pam: pam_mail and pam_env incorrect privilege dropping

Published Jan 24, 2011 CVSS 2.0 · 4.7 Medium EPSS < 1% KEV · Not listed
Description
The privilege-dropping implementation in the (1) pam_env and (2) pam_mail modules in Linux-PAM (aka pam) 1.1.2 does not perform the required setfsgid and setgroups system calls, which might allow local users to obtain sensitive information by leveraging unintended group permissions, as demonstrated by a symlink attack on the .pam_environment file in a user's home directory. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-3435.
