Description Tomáš Kašpárek 2018-07-25 13:56:10 UTC

Description of problem:
rhnlib allows creation of SSLv2 and SSLv3 connections during protocol negotiation as options OP_NO_SSLv2 and OP_NO_SSLv3 are not set.
Although tcdpdump shows that TLSv1.2 is used, we should explicitly forbid usage of SSLv2 and SSLv3.

Version-Release number of selected component (if applicable):
rhnlib-2.5.65-7-el7
