Description

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.
