Package        : curl
CVE ID         : CVE-2018-16890 CVE-2019-3822 CVE-2019-3823

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.

CVE-2019-3823

    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
version 7.52.1-5+deb9u9.

We recommend that you upgrade your curl packages.
