This script is Copyright (C) 2006-2014 Tenable Network Security, Inc.


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-200601-17
(Xpdf, Poppler, GPdf, libextractor, pdftohtml: Heap overflows)

Chris Evans has reported some integer overflows in Xpdf when
attempting to calculate buffer sizes for memory allocation, leading to
a heap overflow and a potential infinite loop when handling malformed
input files.

Impact :

By sending a specially crafted PDF file to a victim, an attacker
could cause an overflow, potentially resulting in the execution of
arbitrary code with the privileges of the user running the application.

Workaround :

There is no known workaround at this time.

# emerge --sync
# emerge --ask --oneshot --verbose '>=app-text/xpdf-3.01-r5'
All Poppler users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-text/poppler-0.4.3-r4'
All GPdf users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-text/gpdf-2.10.0-r3'
All libextractor users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-libs/libextractor-0.5.9'
All pdftohtml users should migrate to the latest stable version
of Poppler.
