This critical patch resolves the following issues:

• Under certain extreme conditions, the tlsagent process may not be able to start successfully when you restart all IMSVA services. When this happens, IMSVA will not be able to receive email messages.
  This critical patch ensures that the tlsagent process can start successfully when restarting all IMSVA services.
• An issue causes IMSVA to treat ATSE 9.860 as an older version of itself. As a result, both the "atse_afi_macro_detect" or "atse_password_guessing" hidden key setting in the IMSVA file will not work properly.
  This critical patch ensures that IMSVA can detect the ATSE version correctly.
• The glibc module in IMSVA 9.0 is affected by a certain vulnerability.
  This critical patch updates the glibc module in IMSVA 9.0 to remove the vulnerability.

Trend Micro recommends that you apply this critical patch on IMSVA 9.0.
