Description


A vulnerability has been reported in GnuTLS, which can potentially be exploited by malicious people to cause a DoS (Denial of Service).

NOTE: Execution of arbitrary code has not been proven, but cannot be completely ruled out.

The vulnerability is reported in version 2.3.5. through 2.4.0.
