cURL/libcURL 7.x < 7.35.0 Multiple Vulnerabilities

Medium Nessus Network Monitor Plugin ID 8178


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.


Versions of cURL/libcURL older than 7.35.0 are unpatched for the following vulnerabilities:

- Security-bypass vulnerability because recent authenticated connections are allowed to be re-used, which an attacker can leverage to perform certain operations with the credentials of a recently authenticated user. (CVE-2014-0138)

- SSL certificate validation error wherein an IP address containing wildcard characters within the Common Name field is not properly validated; this can be leveraged for man-in-the-middle attacks or trusted server impersonation. (CVE-2014-0139)


Upgrade the affected packages; the next version of cURL/libcURL that fixes the issue is cURL 7.35.0.
