Security update for logback (important)

An update that fixes one vulnerability is now available.

Description:

This update for logback fixes the following issues:

Upgrade to version 1.2.8

• In response to log4Shell/CVE-2021-44228, all JNDI lookup code in logback
  has been disabled until further notice. This impacts ContextJNDISelector
  and insertFromJNDI element in configuration files.
• Also in response to log4Shell/CVE-2021-44228, all database (JDBC)
  related code in the project has been removed with no replacement.
• Note that the vulnerability mentioned in LOGBACK-1591 requires write
  access to logback’s configuration file as a prerequisite. The
  log4Shell/CVE-2021-44228 and LOGBACK-1591 are of different severity
  levels. A successful RCE requires all of the following conditions to be
  met:
  • write access to logback.xml
  • use of versions lower then 1.2.8
  • reloading of poisoned configuration data, which implies application
    restart or scan=“true” set prior to attack
