Attack profile from CVSS 2.0 · NVD. Fix status from CNA and Red Hat. Impact type from CWE-399 and the CVSS impact.

Summary

Sendmail before 8.13.7 allows remote attackers to cause a denial of service via deeply nested, malformed multipart MIME messages that exhaust the stack during the recursive mime8to7 function for performing 8-bit to 7-bit conversion, which prevents Sendmail from delivering queued messages and might lead to disk consumption by core dump files.
