RHSA-2005:018 - Security Advisory

Topic

Updated Xpdf packages that fix several security issues are now available.

Description

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.

Red Hat believes that the Exec-Shield technology (enabled by default since
Update 3) will block attempts to exploit this vulnerability on x86
architectures.

All users of the Xpdf packages should upgrade to these updated packages,
which resolve these issues.
