Ubuntu 4.10 / 5.04 : xpdf vulnerability (USN-163-1)

Low Nessus Plugin ID 20569


The remote Ubuntu host is missing one or more security-related patches.


xpdf and kpdf did not sufficiently verify the validity of the 'loca' table in PDF files, a table that contains glyph description information for embedded TrueType fonts. After detecting the broken table, xpdf attempted to reconstruct the information in it, which caused the generation of a huge temporary file that quickly filled up available disk space and rendered the application unresponsive.

The CUPS printing system in Ubuntu 5.04 uses the xpdf-utils package to convert PDF files to PostScript. By attempting to print such a crafted PDF file, a remote attacker could cause a Denial of Service in a print server. The CUPS system in Ubuntu 4.10 is not vulnerable against this attack.

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.


Update the affected packages.
