Description

The remote host is affected by the vulnerability described in GLSA-200904-07 (Xpdf: Untrusted search path)

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.
