CVE-2019-3823 Open this link in a new tabHow to fix?
Upgrade Debian:12 curl to version 7.64.0-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
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.
