An updated apr package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The Apache Portable Runtime (APR) is a portability library used by the Apache HTTP Server and other projects. It provides a free library of C data structures and routines.
Previously, a bug in the handling of IPv6 sockets was present in the apr_mcast_hops() function. This bug could have prevented applications from successfully using multicast with IPv6 sockets. With this update, this bug has been fixed so that the applications now operate correctly.
All APR users are advised to install this newly released package, which fixes this bug.
