Severity:	normal
Title:	CUPS: Arbitrary file read/write
Date:	04/07/2014
Bugs:	#442926
ID:	201404-01

Synopsis

A vulnerability in CUPS may allow for arbitrary file access.

Background

CUPS, the Common Unix Printing System, is a full-featured print server.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-print/cups	< 1.6.2-r5	>= 1.6.2-r5	All supported architectures

Description

Members of the lpadmin group have admin access to the web interface, where they can edit the config file and set some “dangerous” directives (like the logfilenames), which enable them to read or write files as the user running the CUPS webserver.

Impact

A local attacker could possibly exploit this vulnerability to read or write files as the user running the CUPS webserver.

Workaround

There is no known workaround at this time.

Resolution

All CUPS users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-print/cups-1.6.2-r5"
