OpenBSD Errata: August 2nd, 2019 (smtpd)

2 August, 2019 by tj@openbsd.org | openbsd

Errata patches for OpenSMTPD have been released for OpenBSD 6.4 and 6.5.

smtpd can crash on excessively large input, causing a denial of service.

Binary updates for the amd64, i386, and arm64 platforms are available
via the syspatch utility. Source code patches can be found on the
respective errata page:

  https://www.openbsd.org/errata64.html
  https://www.openbsd.org/errata65.html

After patching, restart the smtpd service.
