Description David Walser 2014-01-09 18:23:55 CET

http://www.cups.org/ shows that 1.7.1 fixes this:
http://www.cups.org/str.php?L4319

It's not entirely clear if the CVE-2013-6891 mentioned in that bug is for this issue.

This should affect us since our lppasswd binary is setuid.  This is the case in Mageia 3 as well.

It appears the CVE reference is correct.

Assigning Mageia 3 update to QA.

Advisory:
========================

Updated cups packages fix security vulnerability:

Jann Horn discovered that the CUPS lppasswd tool incorrectly read a user
configuration file in certain configurations. A local attacker could use
this to read sensitive information from certain files, bypassing access
restrictions (CVE-2013-6891).
