"Dear Oracle Customer,
You are receiving this email because our records indicated you
downloaded Critical Patch Update July 2005 (CPUJul2005) or October 2005
(CPUOct2005) patches for Oracle Database version 126.96.36.199 Patch 21 (Patch
4437058) or Patch 23 (4554818) for the Windows platform.
Due to a patching error, a critical Windows specific fix related to
Oracle Enterprise Manager (OEM) is not included on the Windows patches.
If OEM was not installed, no action is required. If OEM was installed,
the 'Installed Products' option in the Oracle Universal Installer will
include "Oracle Enterprise Manager Products". In such case, to secure
your system from the vulnerabilities listed in CPUJul2005 and
CPUOct2005, please download and apply interim Patch 3570850, which can
be applied before or after Patch 21 or 23, and also 22. This critical
fix will be included in Oracle Database version 188.8.131.52 Patch 24.
Please accept our apologies for any inconvenience you may have
experienced, and we thank you for your patience and cooperation in
securing your Oracle server products.
