RHBA-2012:0433 - Bug Fix Advisory

Topic

An updated openssl-ibmca package that fixes one bug is now available for Red Hat
Enterprise Linux 6.

Description

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

This update fixes the following bug:

• Due to a bug in the ibmca OpenSSL engine code, applications using the OpenSSL

library terminated unexpectedly with a segmentation fault when running the ibmca
engine with ciphers enabled in output feedback (OFB) mode on IBM System z, z196
series, hardware. A patch has been applied to address this issue, ensuring that
the OpenSSL library no longer crashes under these circumstances. (BZ#804612)

All users of openssl-ibmca are advised to upgrade to this updated package, which
fixes this bug.
