CVE-2017-3599

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent:
Server: Pluggable Auth). Supported versions that are affected are 5.6.35
and earlier and 5.7.17 and earlier. Easily “exploitable” vulnerability
allows unauthenticated attacker with network access via multiple protocols
to compromise MySQL Server. Successful attacks of this vulnerability can
result in unauthorized ability to cause a hang or frequently repeatable
crash (complete DOS) of MySQL Server. CVSS 3.0 Base Score 7.5 (Availability
impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
NOTE: the previous information is from the April 2017 CPU. Oracle has not
commented on third-party claims that this issue is an integer overflow in
sql/auth/sql_authentication.cc which allows remote attackers to cause a
denial of service via a crafted authentication packet.
