1079149: CVE-2014-0139 curl: IP address wildcard certificate validation issue in libcurl

The MITRE CVE dictionary describes this issue as:

cURL and libcurl 7.1 before 7.36.0, when using the OpenSSL, axtls, qsossl or gskit libraries for TLS, recognize a wildcard IP address in the subject's Common Name (CN) field of an X.509 certificate, which might allow man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.

Statement

This issue did not affect the versions of curl as shipped with Red Hat Enterprise Linux 6 and 7 because it uses the NSS backend, not OpenSSL. It does affect Red Hat Enterprise Linux 5 which uses the OpenSSL backend.

Red Hat Enterprise Linux 5 is now in Production 3 Phase of the support and maintenance life cycle. This has been rated as having Low security impact and is not currently planned to be addressed in future updates. For additional information, refer to the Red Hat Enterprise Linux Life Cycle: https://access.redhat.com/support/policy/updates/errata/.
