A vulnerability in Xpdf might allow local attackers to execute arbitrary code.
|Package||app-text/xpdf on all architectures|
|Affected versions||< 3.02-r2|
|Unaffected versions||>= 3.02-r2|
Xpdf is a PDF file viewer that runs under the X Window System.
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.
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.
Do not run Xpdf from untrusted working directories.
All Xpdf users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/xpdf-3.02-r2"
