Description

The pam_sm_close_session function in pam_xauth.c in the pam_xauth module in Linux-PAM (aka pam) 1.1.2 and earlier does not properly handle a failure to determine a certain target uid, which might allow local users to delete unintended files by executing a program that relies on the pam_xauth PAM check.

Affected products

Linux-PAM: through 1.1.2; 0.99.1.0, 0.99.2.0, 0.99.2.1, 0.99.3.0, 0.99.4.0, 0.99.5.0 (+17)
