USN9-1 : tetex-bin vulnerabilities Vulnerability Scan

Vulnerability Scan Summary
tetex-bin vulnerabilities

Detailed Explanation for this Vulnerability Test

Synopsis :

These remote packages are missing security patches :
- libkpathsea-dev
- libkpathsea3
- tetex-bin

Description :

Chris Evans and Marcus Meissner recently discovered several integer
overflow vulnerabilities in xpdf, a viewer for PDF files. Because
tetex-bin contains xpdf code, it is also affected. These
vulnerabilities could be exploited by a possible hacker providing a
specially crafted TeX, LaTeX, or PDF file. Processing such a file with
pdflatex could result in abnormal program termination or the execution
of program code supplied by the attacker.

This bug could be exploited to gain the rights of the user
invoking pdflatex.

Solution :

Upgrade to :
- libkpathsea-dev-2.0.2-21ubuntu0.1 (Ubuntu 4.10)
- libkpathsea3-2.0.2-21ubuntu0.1 (Ubuntu 4.10)
- tetex-bin-2.0.2-21ubuntu0.1 (Ubuntu 4.10)

Threat Level: High
