GLSA-200501-30 : CUPS: Stack overflow in included Xpdf code
High Nessus Plugin ID 16421
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200501-30 (CUPS: Stack overflow in included Xpdf code)
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.
SolutionAll CUPS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-print/cups-1.1.23-r1'
