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"
