Summary

The CVE-20117-16516 had been addressed already in DLA-3478, however the
fix has been found to be incomplete as it missed an additional memory
leak. This update fixes that problem.

CVE-2017-16516

When a crafted JSON file is supplied to yajl, the process might
crash with a SIGABRT in the yajl_string_decode function in
yajl_encode.c. This results potentially in a denial of service.

CVE-2022-24795

The 1.x branch and the 2.x branch of `yajl` contain an integer
overflow which leads to subsequent heap memory corruption when dealing
with large (~2GB) inputs.

CVE-2023-33460

There's a memory leak in yajl 2.1.0 with use of yajl_tree_parse
function, which potentially cause out-of-memory in server and cause
crash.

For Debian 10 buster, these problems have been fixed in version
2.1.0-3+deb10u2.

We recommend that you upgrade your yajl packages.
