Ubuntu 4.10 : sharutils vulnerability (USN-104-1)

High Nessus Plugin ID 20490


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


Joey Hess discovered that 'unshar' created temporary files in an insecure manner. This could allow a symbolic link attack to create or overwrite arbitrary files with the privileges of the user invoking the program.

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 sharutils and / or sharutils-doc packages.
