Ubuntu 4.10 / 5.04 / 5.10 : netpbm-free vulnerabilities (USN-218-1)
Medium Nessus Plugin ID 20636
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionTwo buffer overflows were discovered in the 'pnmtopng' tool, which were triggered by processing an image with exactly 256 colors when using the -alpha option (CVE-2005-3662) or by processing a text file with very long lines when using the -text option (CVE-2005-3632).
A remote attacker could exploit these to execute arbitrary code by tricking an user or an automated system into processing a specially crafted PNM file with pnmtopng.
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 packages.
