Severity: Normal Title: Xpdf, GPdf: New integer overflows Date: December 28, 2004 Bugs: #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 / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/xpdf <= 3.00-r6 >= 3.00-r7 2 app-text/gpdf <= 2.8.1 >= 2.8.1-r1 ------------------------------------------------------------------- 2 affected packages on all of their 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:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/xpdf-3.00-r7"
All GPdf users should also upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/gpdf-2.8.1-r1"
