cURL/libcURL 7.x < 7.38.0 Multiple Vulnerabilities

Medium Nessus Network Monitor Plugin ID 8385

Synopsis

The cURL program is a library and command-line tool for transferring data using various protocols, including HTTP, FTP, and LDAP. A vulnerable version of cURL was detected from the host.

Description

Versions of cURL/libcURL older than 7.38.0 are unpatched for the following remote security bypass vulnerabilities due to errors in the way it handles cookies:

- Handling of IP addresses in cookie domain when parsing received HTTP cookies can be leveraged to obtain sensitive information, such as HTTP cookies (CVE-2014-3613)

- Failure to restrict libcurl-based HTTP clients from leaking cookie information, which can be leveraged by setting cookies to Top Level Domains (TLD) to bypass security restrictions to an unrelated site or domain (CVE-2014-3620)

Solution

Upgrade the affected packages; the next version of cURL/libcURL that fixes the issue is cURL 7.38.0.
