high Nessus Plugin ID 16419

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200501-28 (Xpdf, GPdf: Stack overflow in Decrypt::makeFileKey2)

 iDEFENSE reports that the Decrypt::makeFileKey2 function in Xpdf's Decrypt.cc insufficiently checks boundaries when processing /Encrypt /Length tags in PDF files.
 Impact :

 An attacker could entice an user to open a specially crafted PDF file which would trigger a stack overflow, potentially resulting in execution of arbitrary code with the rights of the user running Xpdf or GPdf.
 Workaround :

 There is no known workaround at this time.

Solution

All Xpdf users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=app-text/xpdf-3.00-r8' All GPdf users should also upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=app-text/gpdf-2.8.2'
