Ubuntu 8.10 : curl regression (USN-726-2)
Medium Nessus Plugin ID 36478
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionUSN-726-1 fixed a vulnerability in curl. Due to an incomplete fix, a regression was introduced in Ubuntu 8.10 that caused certain types of URLs to fail. This update fixes the problem. We apologize for the inconvenience.
It was discovered that curl did not enforce any restrictions when following URL redirects. If a user or automated system were tricked into opening a URL to an untrusted server, an attacker could use redirects to gain access to arbitrary files. This update changes curl behavior to prevent following 'file' URLs after a redirect.
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.
