Description Andrej Nemec 2016-03-14 08:44:46 UTC

The ProFTPD daemon supports TLS encrypted connections via the mod_tls module. This module has a configuration option TLSDHParamFile to specify user-defined Diffie Hellman parameters.

A vulnerability was found in ProFTPD before 1.3.5b. The software would ignore the user-defined parameters and use Diffie Hellman key exchanges with 1024 bit
