Ubuntu 6.06 LTS / 8.04 LTS / 9.04 / 9.10 / 10.04 LTS : libwww-perl vulnerability (USN-981-1)

Medium Nessus Plugin ID 49066


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


It was discovered that libwww-perl incorrectly filtered filenames suggested by Content-Disposition headers. If a user were tricked into downloading a file from a malicious site, a remote attacker could overwrite hidden files in the user's directory.

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 libwww-perl package.
