Affected: Ubuntu:Pro:16.04:LTS: fetchmail, Ubuntu:Pro:18.04:LTS: fetchmail, Ubuntu:Pro:20.04:LTS: fetchmail

report_vbuild in report.c in Fetchmail before 6.4.20 sometimes omits initialization of the vsnprintf va_list argument, which might allow mail servers to cause a denial of service or possibly have unspecified other impact via long error messages. NOTE: it is unclear whether use of Fetchmail on any realistic platform results in an impact beyond an inconvenience to the client user.
