Debian 10: DLA-3373-1 Critical: Json-Smart Denial Of Service

CVE-2021-31684

A vulnerability was discovered in the indexOf function of
JSONParserByteArray in JSON Smart versions 1.3 and 2.4
which causes a denial of service (DOS)
via for instance a crafted web request.

CVE-2023-1370

A stack overflow was found due to excessive recursion.
When reaching a ‘[‘ or ‘{‘ character in the JSON input, the code
parses an array or an object respectively. It was discovered that the
code does not have any limit to the nesting of such arrays or
objects. Since the parsing of nested arrays and objects is done
recursively, nesting too many of them can cause a stack exhaustion
(stack overflow) and crash the software

For Debian 10 buster, these problems have been fixed in version
2.2-2+deb10u1.

We recommend that you upgrade your json-smart packages.
