Georgi Guninski reported that long Content-Type headers in external message bodies could cause a heap buffer overflow when processing mail headers. While working on that code David Bienvenu discovered a similar overflow could occur when processing long rfc2047-encoded headers.
Either overflow could be exploited to execute arbitrary code.
None, upgrade to a fixed version immediately.
