USN14-1 : xpdf vulnerabilities

Vulnerability Assessment Summary
xpdf vulnerabilities

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- cupsys
- cupsys-bsd
- cupsys-client
- libcupsimage2
- libcupsimage2-dev
- libcupsys2-dev
- libcupsys2-gnutls10
- libkpathsea-dev
- libkpathsea3
- tetex-bin
- xpdf
- xpdf-common
- xpdf-reader
- xpdf-utils


Description :

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 a possible hacker 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 rights of
the CUPS print server (by default, user cupsys).

In the cases of xpdf and pdflatex, this bug could be exploited to gain
the rights of the user invoking the program.

Solution :

Upgrade to :
- cupsys-1.1.20final+cvs20040330-4ubuntu16.2 (Ubuntu 4.10)
- cupsys-bsd-1.1.20final+cvs20040330-4ubuntu16.2 (Ubuntu 4.10)
- cupsys-client-1.1.20final+cvs20040330-4ubuntu16.2 (Ubuntu 4.10)
- libcupsimage2-1.1.20final+cvs20040330-4ubuntu16.2 (Ubuntu 4.10)
- libcupsimage2-dev-1.1.20final+cvs20040330-4ubuntu16.2 (Ubuntu 4.10)
- libcupsys2-dev-1.1.20final+cvs20040330-4ubuntu16.2 (Ubuntu 4.10)
- libcupsys2-gnutls10-1.1.20final+cvs20040330-4ubuntu16.2 (Ubuntu 4.10)
- libkpathsea-dev-2.0.2-21ubuntu0.
