Use CVE-2014-3462 for that issue, i.e., 'The purpose of MAC headers is to prevent an attacker with read/write access to the ciphertext from being able to make changes without being detected. Unfortunately, this feature provides little security, since it is controlled by an option in the .encfs6.xml configuration file (part of the ciphertext), so the attacker can just disable it by setting "blockMACBytes" to 0 and adding 8 to "blockMACRandBytes" (so that the MAC is not interpreted as data).' - -- CVE assignment team, MITRE CVE Numbering Authority M/S M300 202 Burlington Road, Bedford, MA 01730 USA [ PGP key available through http://cve.mitre.org/cve/request_id.html ] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (SunOS) iQEcBAEBAgAGBQJTcwbzAAoJEKllVAevmvms59MIALliH0nQBEhTa971v2fghjQS XW43V8j42cD4i2yR91GfhJMCilyrRlxY1IQS7isleOQNBufmUavOs4gZmq1A+EGv YD7F7MrQjLOKGLyl1aGbr5YpNmbYJONgqDnnpDdramjKo1MZKr/qexOLn51lLJQJ J1RUaZIm+tccToBmkyhHS6rmHF/kutlvXt1goHKPkWaBWIdCz8zkPZWASj1D4KYX Ynxtc+ikC60AdhQp1ggTmWff0NDnfjI7DUDWM88DbfLfGJ48/uAatgcEhKns326l Z4eomykAB4IA62fgm0XisPrXNpibQs2aEOfr3fDwyCRBi7IA5y7C2SCFZ9V37bM= =Rfv2 -----END PGP SIGNATURE-----
