Ubuntu 5.04 / 5.10 / 6.06 LTS / 6.10 : screen vulnerability (USN-370-1)

Low Nessus Plugin ID 27951


The remote Ubuntu host is missing a security-related patch.


cstone and Rich Felker discovered a programming error in the UTF8 string handling code of 'screen' leading to a denial of service. If a crafted string was displayed within a screen session, screen would crash or possibly execute arbitrary code.

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 screen package.
