| Description: | Description:
The remote host is missing an update to xpdf
announced via advisory USN-14-1.
Markus Meissner discovered even more integer overflow vulnerabilities
in xpdf, a viewer for PDF files. These integer overflows can
eventually lead to buffer overflows.
The Common UNIX Printing System (CUPS) uses the same code to print PDF
files
tetex-bin uses the code to generate PDF output and process
included PDF files. In any case, these vulnerabilities could be
exploited by an attacker providing a specially crafted PDF file which,
when processed by CUPS, xpdf, or pdflatex, could result in abnormal
program termination or the execution of program code supplied by the
attacker.
In the case of CUPS, this bug could be exploited to gain the privileges of
the CUPS print server (by default, user cupsys).
In the cases of xpdf and pdflatex, this bug could be exploited to gain
the privileges of the user invoking the program.
The following packages are affected:
xpdf-reader
xpdf-utils
cupsys
tetex-bin
Solution:
The problem can be corrected by upgrading the affected package(s) to
version 1.1.20final+cvs20040330-4ubuntu16.2 (cupsys), version
3.00-8ubuntu1.2 (xpdf-reader, xpdf-utils), or version
2.0.2-21ubuntu0.2 (tetex-bin). In general, a standard system upgrade
is sufficient to effect the necessary changes.
