RHBA-2015:0792 - openssl-ibmca bug fix update

Synopsis

openssl-ibmca bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated openssl-ibmca packages that fix two bugs are now available for Red Hat Enterprise Linux 6.

Description

The openssl-ibmca packages provide a dynamic OpenSSL engine for the IBM eServer Cryptographic Accelerator (ICA) crypto hardware on IBM eServer zSeries machines.

This update fixes the following bugs:

  • Prior to this update, an incorrect flag was passed to the elliptic curve crypto signing method. Consequently, the selftest in the OpenSSL library failed when the IBMCA engine was in use. Now, the correct flag is passed, and the OpenSSL selftest succeeds. (BZ#1075183)

  • Previously, the IBMCA engine truncated the SHA256 hash data computed by the Library for IBM Cryptographic Architecture (libica). As a consequence, the certificate verification process used a malformed hash and failed. Now, the correct length is used for the SHA256 data, and certificate verification proceeds without errors. (BZ#1193071)

Users of openssl-ibmca are advised to upgrade to these updated packages, which fix these bugs.

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.
