Red Hat Errata System 5.3 2011-05-02T14:29:50 Red Hat Enterprise Linux 4 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. Important Copyright 2005 Red Hat, Inc.
