Multiple vulnerabilities were discovered in cURL, an URL transfer library.
CVE-2018-16890
Wenxiang Qian of Tencent Blade Team discovered that the function
handling incoming NTLM type-2 messages does not validate incoming
data correctly and is subject to an integer overflow vulnerability,
which could lead to an out-of-bounds buffer read.
CVE-2019-3822
Wenxiang Qian of Tencent Blade Team discovered that the function
creating an outgoing NTLM type-3 header is subject to an integer
overflow vulnerability, which could lead to an out-of-bounds write.

Brian Carpenter of Geeknik Labs discovered that the code handling
the end-of-response for SMTP is subject to an out-of-bounds heap
read.
For the stable distribution (stretch), these problems have been fixed in
