CVE-2010-4707

Publication date 24 January 2011

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The check_acl function in pam_xauth.c in the pam_xauth module in Linux-PAM (aka pam) 1.1.2 and earlier does not verify that a certain ACL file is a regular file, which might allow local users to cause a denial of service (resource consumption) via a special file.
