CVE-2010-3316 Information

Description

The run_coprocess function in pam_xauth.c in the pam_xauth module in Linux-PAM (aka pam) before 1.1.2 does not check the return values of the setuid setgid and setgroups system calls which might allow local users to read arbitrary files by executing a program that relies on the pam_xauth PAM check.
