Updated yum-metadata-parser packages that fix one bug are now available for Red Hat Enterprise Linux 5.
The yum-metadata-parser packages provide a fast metadata parser for Yum implemented in C.
If the primary.xml file contained malformed data, the yum-metadata-parser utility terminated unexpectedly due to a NULL pointer dereference. The underlying source code has been modified, so that yum-metadata-parser exits gracefully with an error message in this scenario.
All users of yum-metadata-parser are advised to upgrade to these updated packages, which fix this bug.
