Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
A vulnerability in CUPS might allow for the execution of arbitrary code
or a Denial of Service.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
CUPS provides a portable printing layer for UNIX-based operating
systems.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected

1 net-print/cups < 1.2.12-r8 >=3D 1.2.12-r8=
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Thomas Pollet reported a possible integer overflow vulnerability in the
PNG image handling in the file filter/image-png.c.
Impact
=3D=3D=3D=3D=3D=3D
A malicious user might be able to execute arbitrary code with the
privileges of the user running CUPS (usually lp), or cause a Denial of
Service by sending a specially crafted PNG image to the print server.
The vulnerability is exploitable via the network if CUPS is sharing
printers remotely.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All CUPS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dnet-print/cups-1.2.12-r8"
