Описание
libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to smtp_endofresp() isn't NUL terminated and contains no character ending the parsed number, and len is set to 5, then the strtol() call reads beyond the allocated buffer. The read contents will not be returned to the caller.
An out-of-bounds read flaw was found in the way curl handled certain SMTP responses. A remote attacker could use this flaw to crash curl.
Меры по смягчению последствий
Do not use SMTP authentication with curl
