Gentoo Linux Security Advisory
Title: Xpdf, GPdf: New integer overflows (GLSA 200412-24)
Severity: normal
Exploitable: remote
Date: December 28, 2004
Bug(s): #75191, #75201
ID: 200412-24
Synopsis
New integer overflows were discovered in Xpdf, potentially resulting in the execution of arbitrary code. GPdf includes Xpdf code and therefore is vulnerable to the same issues.
Background
Xpdf is an open source viewer for Portable Document Format (PDF) files. GPdf is a Gnome-based PDF viewer that includes some Xpdf code.
Affected Packages
Package: app-text/xpdf
Vulnerable: <= 3.00-r6
Unaffected: >= 3.00-r7
Architectures: All supported architectures
Package: app-text/gpdf
Vulnerable: <= 2.8.1
Unaffected: >= 2.8.1-r1
Architectures: All supported architectures
Description
A new integer overflow issue was discovered in Xpdf's Gfx::doImage() function.
Impact
An attacker could entice an user to open a specially-crafted PDF file, potentially resulting in execution of arbitrary code with the rights of the user running Xpdf or GPdf.
Workaround
There is no known workaround at this time.
Resolution
All Xpdf users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/xpdf-3.00-r7" | All GPdf users should also upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/gpdf-2.8.1-r1" |
