The following packages have been upgraded to a newer upstream version: mod_nss . Security Fix: * 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. This issue was discovered by Rob Crittenden .
