   An update that fixes one vulnerability is now available.


   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
     - 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
