Multiple vulnerabilities have been discovered in Xpdf, GPdf, CUPS and Poppler potentially resulting in the execution of arbitrary code.
| Package | app-text/xpdf on all architectures |

| Package | app-text/poppler on all architectures |
|---|---|
| Affected versions | < 0.4.2-r1 |
| Unaffected versions | >= 0.4.2-r1 revision >= 0.3.0-r1 |

Xpdf and GPdf are PDF file viewers that run under the X Window System. Poppler is a PDF rendering library based on Xpdf code. The Common UNIX Printing System (CUPS) is a cross-platform print spooler. It makes use of Xpdf code to handle PDF files.
infamous41md discovered that several Xpdf functions lack sufficient boundary checking, resulting in multiple exploitable buffer overflows.
An attacker could entice a user to open a specially-crafted PDF file which would trigger an overflow, potentially resulting in execution of arbitrary code with the rights of the user running Xpdf, CUPS, GPdf or Poppler.
There is no known workaround at this time.
All Xpdf users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/xpdf-3.01-r2"
All GPdf users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/gpdf-2.10.0-r2"
All Poppler users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose app-text/poppler
All CUPS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-print/cups-1.1.23-r3"
