Ubuntu 4.10 : cdrtools vulnerability (USN-100-1)
High Nessus Plugin ID 20486
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionJavier Fernandez-Sanguino Pena noticed that cdrecord created temporary files in an insecure manner if DEBUG was enabled in /etc/cdrecord/rscsi. If the default value was used (which stored the debug output file in /tmp), this could allow a symbolic link attack to create or overwrite arbitrary files with the privileges of the user invoking cdrecord.
Please note that DEBUG is not enabled by default in Ubuntu, so if you did not explicitly enable it, this does not affect you.
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.
