Oracle MySQL Connectors DoS (Jul 2018 CPU)

medium Nessus Plugin ID 129004


The remote host is affected by a Denial of Service vulnerability.


The version of Oracle MySQL Connectors installed on the remote host is 8.0.x prior to 8.0.12 or 5.3.x prior to 5.3.11.
It is, therefore, affected by a denial of service vulnerability as noted in the July 2018 Critical Patch Update advisory. This vulnerability is related to OpenSSL's handling of recursive ASN.1 structures: given specially crafted input with excessive recursion, an attacker can cause a stack overflow that results in a denial of service.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Apply the appropriate patches according to the July 2018 Oracle Critical Patch Update advisory.
