CVE-2015-5244
First published: Wed Sep 02 2015(Updated: )
The NSSCipherSuite option of mod_nss accepts OpenSSL-styled cipherstrings. It was found that the parsing of such cipherstrings is flawed. If this option is used to disable insecure ciphersuites using the common "!" syntax, e.g.: NSSCipherSuite !eNULL:!aNULL:AESGCM+aRSA:ECDH+aRSA it will actually enable those insecure ciphersuites. Acknowledgements: This issue was discovered Hubert Kario of Red Hat.
