Package        : graphviz
Version        : 2.38.0-17+deb9u1
CVE ID         : CVE-2018-10196 CVE-2020-18032
Debian Bug     : 898841 988000


    NULL pointer dereference vulnerability in the rebuild_vlists
    function in lib/dotgen/conc.c in the dotgen library allows
    remote attackers to cause a denial of service (application
    crash) via a crafted file.


    A buffer overflow was discovered in Graphviz, which could
    potentially result in the execution of arbitrary code when
    processing a malformed file.

For Debian 9 stretch, these problems have been fixed in version

We recommend that you upgrade your graphviz packages.
