- password tries were lost when connection errors happened (thanks to Vineet Kumar for reporting)
|
||||
- fixed crash when used together with -e option
|
||||
* Fixed a bug that hydra would not compile without libssh (introduced in v7.6)
|
||||
* Various bugfixes if many targets where attacked in parallel
|
||||
* Cygwin's Postgresql is working again, hence configure detection re-enabled
|
||||
* Added gcc compilation security options (if detected to be supported by configure script)
|
||||
* Enhancements to the secure compilation options
|
||||
* Checked code with cppcheck and fixed some minor issues. surprised it were so few and unlikely stuff :-)
|
||||
* Checked code with cppcheck and fixed some minor issues.
|
||||
* Checked code with Coverity. Fixed a lot of small and medium issues.
