The following packages have been upgraded to a newer upstream version:

Security Fix(es) :
* A flaw was found in the way mod_nss parsed certain OpenSSL-style
cipher strings. As a result, mod_nss could potentially use ciphers
that were not intended to be enabled. (CVE-2016-3099)
This issue was discovered by Rob Crittenden (Red Hat).
