Synopsis ========
A vulnerability in CUPS might allow for the execution of arbitrary code or a Denial of Service.
Background ==========
CUPS provides a portable printing layer for UNIX-based operating systems.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-print/cups < 1.2.12-r8 >=3D 1.2.12-r8=
Description ===========
Thomas Pollet reported a possible integer overflow vulnerability in the PNG image handling in the file filter/image-png.c.
Impact ======
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 ==========
There is no known workaround at this time.
Resolution ==========
All CUPS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Dnet-print/cups-1.2.12-r8"
