Details

An updated gpdf package that fixes two security issues is now available.

This update has been rated as having important security impact by the Red Hat
Security Response Team.

GPdf is a viewer for Portable Document Format (PDF) files for GNOME.

A buffer overflow flaw was found in the Gfx::doImage function of Xpdf which
also affects GPdf due to a shared codebase. An attacker could construct a
carefully crafted PDF file that could cause GPdf to crash or possibly
execute arbitrary code when opened. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-1125 to
this issue.

A buffer overflow flaw was found in the Decrypt::makeFileKey2 function of
Xpdf which also affects GPdf due to a shared codebase. An attacker could
construct a carefully crafted PDF file that could cause GPdf to crash or
possibly execute arbitrary code when opened. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2005-0064 to
this issue.

During a source code audit, Chris Evans and others discovered a number of
integer overflow bugs that affected all versions of Xpdf, which also
affects GPdf due to a shared codebase. An attacker could construct a
carefully crafted PDF file that could cause GPdf to crash or possibly
execute arbitrary code when opened. This issue was assigned the name
CAN-2004-0888 by The Common Vulnerabilities and Exposures project
(cve.mitre.org). Red Hat Enterprise Linux 4 contained a fix for this issue,
but it was found to be incomplete and left 64-bit architectures vulnerable.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2005-0206 to this issue.

Users should update to this erratum package which contains backported
patches to correct these issues.
