Ubuntu 4.10 / 5.04 / 5.10 : curl vulnerability (USN-228-1)

medium Nessus Plugin ID 20771

Synopsis

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

Description

Stefan Esser discovered several buffer overflows in the handling of URLs. By attempting to load an URL with a specially crafted invalid hostname, a local attacker could exploit this to execute arbitrary code with the privileges of the application that uses the cURL library.

It is not possible to trick cURL into loading a malicious URL with an HTTP redirect, so this vulnerability was usually not exploitable remotely. However, it could be exploited locally to e. g. circumvent PHP security restrictions.

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.
