Oracle Critical Patch Update Advisory - April 2019

Oracle Critical Patch Update Advisory - April 2019

--------------------------------------------------------------------------------

https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.html

Description

A Critical Patch Update is a collection of patches for multiple security vulnerabilities. Critical Patch Update patches are usually cumulative, but each advisory describes only the security fixes added since the previous Critical Patch Update advisory. Thus, prior Critical Patch Update advisories should be reviewed for information regarding earlier published security fixes. Please refer to:

• Critical Patch Updates, Security Alerts and Bulletins for information about Oracle Security Advisories.

Oracle continues to periodically receive reports of attempts to maliciously exploit vulnerabilities for which Oracle has already released fixes. In some instances, it has been reported that attackers have been successful because targeted customers had failed to apply available Oracle patches. Oracle therefore strongly recommends that customers remain on actively-supported versions and apply Critical Patch Update fixes without delay.

This Critical Patch Update contains 297 new security fixes across the product families listed below. Please note that an MOS note summarizing the content of this Critical Patch Update and other Oracle Software Security Assurance activities is located at April 2019 Critical Patch Update: Executive Summary and Analysis.
