Oracle CPUs and problems on some platforms
14 Jun 2007 von Alexander Kornbrust.
During our security training we found an interesting forum entry (CPU Oct 2006 Problem) in Oracle Metalink. It seems that a portscan with nmap on AIX 5.2, OAS 10.1.2.0.2 CPUOCT06 causes a denial of service problem on port 443 (HTTPS). It’s not clear if this problem affects all platforms because nobody answered the forum entry.
Normally it is a good idea to apply CPUs as soon but sometimes new bugs are introduced. Often these problems are specific to a special platform. Another example of a bug which was introduced by the CPUOct2006, CPUJan2007 and CPUApr2007 was a rman problem on Windows 32 bit (Rman fails to restore in 9.2.0.8 with CPU patch installed on Windows platform).
Before applying a patch on a production system you should always perform tests.
