CVE-2020-8794 (GCVE-0-2020-8794)

Vulnerability from cvelistv5

Published

2020-02-25 16:38

Modified

2024-08-04 10:12

Severity ?

CWE

Summary

OpenSMTPD before 6.6.4 allows remote code execution because of an out-of-bounds read in mta_io in mta_session.c for multi-line replies. Although this vulnerability affects the client side of OpenSMTPD, it is possible to attack a server because the server code launches the client code during bounce handling.
