Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : curl vulnerability (USN-726-1)

medium Nessus Plugin ID 37148

Synopsis

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

Description

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.

Solution

Update the affected packages.
