release notes:

---------------------------------------------------------------------------------
fetchmail-6.4.20 (released 2021-07-28, 30042 LoC):

# SECURITY FIX:                                                                                                                                                                               
* When a log message exceeds c. 2 kByte in size, for instance, with very long
  header contents, and depending on verbosity option, fetchmail can crash or
  misreport each first log message that requires a buffer reallocation.
  fetchmail then reallocates memory and re-runs vsnprintf() without another
  call to va_start(), so it reads garbage. The exact impact depends on
  many factors around the compiler and operating system configurations used and
  the implementation details of the stdarg.h interfaces of the two functions
  mentioned before. To fix CVE-2021-38386.
