Synopsis
========
Poppler is vulnerable to an integer overflow and a stack overflow.
Background
==========
Poppler is a cross-platform PDF rendering library originally based on
Xpdf.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/poppler < 0.5.4-r2 >= 0.5.4-r2
Description
===========
Poppler and Xpdf are vulnerable to an integer overflow in the
StreamPredictor::StreamPredictor function, and a stack overflow in the
StreamPredictor::getNextLine function. The original vulnerability was
discovered by Maurycy Prodeus. Note: Gentoo's version of Xpdf is
patched to use the Poppler library, so the update to Poppler will also
fix Xpdf.
Impact
======
By enticing a user to view a specially crafted program with a
Poppler-based PDF viewer such as Gentoo's Xpdf, Epdfview, or Evince, a
remote 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.
Resolution
==========
All Poppler users should upgrade to the latest version of Poppler:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/poppler-0.5.4-r2"
References
