CUPS: Stack overflow in included Xpdf code

CUPS: Stack overflow in included Xpdf code CUPS includes Xpdf code and therefore is vulnerable to the recent stack overflow issue, potentially resulting in the remote execution of arbitrary code. CUPS 2005-01-22 2005-01-22 78249 remote 1.1.23-r1 1.1.23-r1

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

The Decrypt::makeFileKey2 function in Xpdf's Decrypt.cc insufficiently checks boundaries when processing /Encrypt /Length tags in PDF files (GLSA 200501-28).

This issue could be exploited by a remote attacker to execute arbitrary code by sending a malicious print job to a CUPS spooler.

There is no known workaround at this time.

All CUPS users should upgrade to the latest version:


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