Package : json-c
Version : 0.12.1-1.1+deb9u1
CVE ID : CVE-2020-12762
Debian Bug : 960326

Tobias Stoeckmann found an integer overflow issue in JSON-C, a C
library to manipulate JSON objects, when reading maliciously crafted
large files. The issue could be exploited to cause denial of service
or possibly execute arbitrary code.

For Debian 9 stretch, this problem has been fixed in version
0.12.1-1.1+deb9u1.

We recommend that you upgrade your json-c packages.

For the detailed security status of json-c please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/json-c
