A null pointer deference flaw was found in OpenSSL's Secure Remote Password (SRP) implementation. An attacker controlling a malicious server could use this flaw to crash a vulnerable client.

The openssl packages shipped in Red Hat Enterprise Linux and Fedora are build with the Secure Remote Password (SRP) support disabled and were therefore not affected by this issue. Also note that SRP support was introduced upstream in version 1.0.1. https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=edc032b https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=0deea0e
Statement: Not vulnerable. This issue did not affect the versions of openssl as shipped with Red Hat Enterprise Linux 5, 6 and 7, Red Hat Enterprise Virtualization 3, and Red Hat Enterprise Storage 2, as they do not enable Secure Remote Password (SRP) support. All other supported Red Hat products that include openssl use older versions that are not affected by this issue.
