Link to RedHat announcement: https://access.redhat.com/security/vulnerabilities/drown I am trying to follow the scope of this issue. RedHat says "TLS servers which support SSLv2 are vulnerable". Can't tell if this means that services with SSLv2 capabilities are vulnerable or only ones with it enabled. -Grant On Tue, Mar 1, 2016 at 9:39 AM, Loganaden Velvindron <loganaden () gmail com> wrote:

Now we have yet another significant SSLv2 problem, DROWN, bad enough in fact that Red Hat has now disabled SSLv2 in OpenSSL by default (already done in NSS/GnuTLS), so from my vendor perspective, we're treating SSLv2 support as a security problem, the solution of which is to remove said support. But more generally, should we look at assigning CVE's for support ofSSLv2,much like we would for products supporting DES or other known insecure cryptographic algorithms, hashes, digests and protocols? My personal vote is for yes.Btw, FreeBSD has done some work there: https://wiki.freebsd.org/LibreSSL/PatchingPorts#SSLv2.2FSSLv3_method_failures Linking with LibreSSL would help uncover those cases, and assign CVEs :)-- Kurt Seifried -- Red Hat -- Product Security -- Cloud PGP A90B F995 7350 148F 66BF 7554 160D 4553 5E26 7993 Red Hat Product Security contact: secalert () redhat com
