RedHat: Important: xpdf security update RHSA-2005:034-01

An updated xpdf package that fixes several security issues is now available. This update has been rated as having important security impact by the Red Hat Security Response Team.

Summary

Xpdf is an X Window System based viewer for Portable Document Format (PDF) files. A buffer overflow flaw was found in the Gfx::doImage function of Xpdf. An attacker could construct a carefully crafted PDF file that could cause Xpdf 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. An attacker could construct a carefully crafted PDF file that could cause Xpdf 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. An attacker could construct a carefully crafted PDF file that could cause Xpdf 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. All users of Xpdf should upgrade to this updated package, which contains backported patches to resolve these issues.
