Synopsis
========
CUPS includes Xpdf code and therefore is vulnerable to the recent stack
overflow issue, potentially resulting in the remote execution of
arbitrary code.
Background
==========
The Common UNIX Printing System (CUPS) is a cross-platform print
spooler. It makes use of Xpdf code to handle PDF files.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-print/cups < 1.1.23-r1 >= 1.1.23-r1
Description
===========
The Decrypt::makeFileKey2 function in Xpdf's Decrypt.cc insufficiently
checks boundaries when processing /Encrypt /Length tags in PDF files
(GLSA 200501-28).
Impact
======
This issue could be exploited by a remote attacker to execute arbitrary
code by sending a malicious print job to a CUPS spooler.
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-1.1.23-r1"
