K55143785: NSS vulnerability CVE-2017-7502

Security Advisory Description Null pointer dereference vulnerability in NSS since 3.24.0 was found when server receives empty SSLv2 messages resulting into denial of service by remote attacker. CVE-2017-7502 Impact There is no impact; F5 products are not affected by this vulnerability. Security...

K95463126: OpenSSL vulnerabilities CVE-2016-0703 and CVE-2016-0704

Security Advisory Description CVE-2016-0703 The getclientmasterkey function in s2srvr.c in the SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a accepts a nonzero CLIENT-MASTER-KEY CLEAR-KEY-LENGTH value for an arbitrary cipher, whic...

K41738501: Mozilla NSS vulnerability CVE-2018-12384

Security Advisory Description When handling a SSLv2-compatible ClientHello request, the server doesn't generate a new random value but sends an all-zero value instead. This results in full malleability of the ClientHello for SSLv2 used for TLS 1.2 in all versions prior to NSS 3.39. This does not...

K16321: OpenSSL vulnerability CVE-2015-0293

Security Advisory Description The SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service s2lib.c assertion failure and daemon exit via a crafted CLIENT-MASTER-KEY message.
