CVE-2010-3430  (opens in a new tab)

How to fix?

Upgrade Debian:13 pam to version 1.1.3-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pam package and not the pam package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

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.
