When reading SMTP server status codes, Thunderbird writes an integer value
to a position on the stack that is intended to contain just one byte.
Depending on processor architecture and stack layout, this leads to stack
corruption that may be exploitable. This vulnerability affects Thunderbird
< 78.5.1.
