[1] IMPACT The vendor has provided the following information regarding to the vulnerabilities. This Critical Patch Update contains 4 new security fixes for the Oracle Database Server divided as follows: [1] "CVE-2017-10202 CVSS Base Score of 8.8. 9.9 AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H Easily exploitable vulnerability allows low privileged attacker having Create Session, Create Procedure privilege with network access via multiple protocols to compromise OJVM. While the vulnerability is in OJVM, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of OJVM. Note: This score is for Windows platforms. On non-Windows platforms Scope is Unchanged,giving a a CVSS Base Score of 8.8. CVE-2014-3566 6.8 AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N Difficult to exploit vulnerability allows unauthenticated attacker with network access via LDAP to compromise DBMS_LDAP. While the vulnerability is in DBMS_LDAP, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all DBMS_LDAP accessible data. CVE-2016-2183 6.8 AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N Difficult to exploit vulnerability allows unauthenticated attacker with network access via SSL/TLS to compromise Real Application Clusters. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Real Application Clusters accessible data as well as unauthorized access to critical data or complete access to all Real Application Clusters accessible data. CVE-2017-10120 1.9 AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:N Difficult to exploit vulnerability allows high privileged attacker having Create Session, Select Any Dictionary privilege with logon to the infrastructure where RDBMS Security executes to compromise RDBMS Security. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of RDBMS Security accessible data." [2] MITIGATION Oracle states: "Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply CPU fixes as soon as possible. Until you apply the CPU fixes, it may be possible to reduce the risk of successful attack by blocking network protocols required by an attack. For attacks that require certain privileges or access to certain packages, removing the privileges or the ability to access the packages from users that do not need the privileges may help reduce the risk of successful attack. Both approaches may break application functionality, so Oracle strongly recommends that customers test changes on non-production systems. Neither approach should be considered a long-term solution as neither corrects the underlying problem."
