Mandriva Linux Security Advisory 2014-151 - In CUPS before 1.7.4, a local user with privileges of group=lp can write symbolic links in the rss directory and use that to gain '@SYSTEM' group privilege with cupsd. It was discovered that the web interface in CUPS incorrectly validated permissions on rss files and directory index files. A local attacker could possibly use this issue to bypass file permissions and read arbitrary files, possibly leading to a privilege escalation.

Package : cups
Date : August 6, 2014
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Updated cups packages fix security vulnerability:

In CUPS before 1.7.4, a local user with privileges of group=lp
can write symbolic links in the rss directory and use that to gain
'@SYSTEM' group privilege with cupsd (CVE-2014-3537).

It was discovered that the web interface in CUPS incorrectly
validated permissions on rss files and directory index files. A local
attacker could possibly use this issue to bypass file permissions
and read arbitrary files, possibly leading to a privilege escalation
(CVE-2014-5029, CVE-2014-5030, CVE-2014-5031).
