Debian DLA-3373-1 : json-smart - LTS security update

high Nessus Plugin ID 173721

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3373 advisory.

- 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 a crafted web request. (CVE-2021-31684)

- [Json-smart](https://netplex.github.io/json-smart/) is a performance focused, JSON processor lib. 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. (CVE-2023-1370)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the json-smart packages.

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