Today Oracle has released its quarterly patch update for October 2016. It fixes a total of 253 vulnerabilities.
The main highlights are as follows:
- 1. This is the second-largest Update containing 253 vulnerability fixes. Almost every Oracle CPU released in 2016 contains more than 200 fixes, while the average number for the years 2011-2015 is approximately 110.
- 2. The updates close a lot of security issues in the business-critical applications from Oracle. For example, Oracle E-Business Suite has the highest number of updates among mission-critical software containing 21 issues where 11 are assessed as high. 14 of them can be exposed online providing an entry point for attackers. The number and criticality of the issues are alarming.
- 3. There is a critical vulnerability in HTTP service of Oracle EBS patched in this update. ERPScan researchers conducted a Shodan scanning and revealed that approximately 15000 Oracle HTTP servers are exposed to the Internet.
Oracle Critical Patch Update October 2016
Comparing with the previous CPU for July 2016 that closed 276 vulnerabilities, this one addresses approximately 11% less security issues. Nonetheless, this it the second largest update in the history

"Oracle started this year by releasing a CPU consisting of 248 patches, which immediately made headlines as a record-breaking number of fixes. As of today, this patch update seems to be a game-changing moment. Looking at the graph above, we can assume that the exceeding the two-hundred mark in terms of number of closed issues was not fortuitousness. This seems to be a trend for all sets of patches released in 2016, and only CPU for April 2016 is at odds with it."
- commented Alexander Polyakov, CTO at ERPScan.
