Title: Xpdf: Untrusted search path ([glsa=200904-07]GLSA 200904-07[/glsa])
Severity: normal
Exploitable: local
Date: April 07, 2009
Bug(s): #242930
ID: 200904-07
Synopsis
A vulnerability in Xpdf might allow local attackers to execute arbitrary
code.
Background
Xpdf is a PDF file viewer that runs under the X Window System.
Affected Packages
Package: app-text/xpdf
Vulnerable: < 3.02-r2
Unaffected: >= 3.02-r2
Architectures: All supported architectures
Description
Erik Wallin reported that Gentoo's Xpdf attempts to read the "xpdfrc"
file from the current working directory if it cannot find a ".xpdfrc"
file in the user's home directory. This is caused by a missing
definition of the SYSTEM_XPDFRC macro when compiling a repackaged
version of Xpdf.
Impact
A local attacker could entice a user to run "xpdf" from a directory
containing a specially crafted "xpdfrc" file, resulting in the
execution of arbitrary code when attempting to, e.g., print a file.
Workaround
Do not run Xpdf from untrusted working directories.
Resolution
All Xpdf users should upgrade to the latest version:
Code: Select all
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/xpdf-3.02-r2"References
