DoS with algorithms that use PBKDF2 due to unbounded PBES2 Count value

Impact

Denial of Service,
Applications that allow the use of the PBKDF2 algorithm.

Patches

A patch is available that sets the maximum number of default rounds.

Workarounds

Applications that do not need to use PBKDF2 should simply specify the algorithms use and exclude it from the list.
Applications that need to use the algorithm should upgrade to the new version that allows to set a maximum rounds number.
