Package : json-c
CVE ID : CVE-2020-12762

Tobias Stoeckmann discovered an integer overflow in the json-c JSON
library, which could result in denial of service or potentially the
execution of arbitrary code if large malformed JSON files are processed.

For the stable distribution (buster), this problem has been fixed in
version 0.12.1+ds-2+deb10u1.

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
