Ubuntu 8.04 LTS / 8.10 : dash vulnerability (USN-732-1)
Medium Nessus Plugin ID 36749
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionWolfgang M. Reimer discovered that dash, when invoked as a login shell, would source .profile files from the current directory. Local users may be able to bypass security restrictions and gain root privileges by placing specially crafted .profile files where they might get sourced by other dash users.
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 ash and / or dash packages.
