CUPS: Stack overflow in included Xpdf code — GLSA 200501-30

CUPS includes Xpdf code and therefore is vulnerable to the recent stack overflow issue, potentially resulting in the remote execution of arbitrary code.

Affected packages

Background

The Common UNIX Printing System (CUPS) is a cross-platform print spooler. It makes use of Xpdf code to handle PDF files.

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

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-print/cups-1.1.23-r1"
