[GLSA]

Gentoo Linux Security Advisory

Title: Poppler: Two buffer overflow vulnerabilities (GLSA 200709-12)
Severity: normal
Exploitable: remote
Date: September 19, 2007
Bug(s): #188863
ID: 200709-12

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: app-text/poppler
Vulnerable: < 0.5.4-r2
Unaffected: >= 0.5.4-r2
Architectures: All supported architectures


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:
