Ubuntu 4.10 : tetex-bin vulnerabilities (USN-9-1)
Critical Nessus Plugin ID 20715
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionChris 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 an attacker 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 privileges of the user invoking pdflatex.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected libkpathsea-dev, libkpathsea3 and / or tetex-bin packages.
