Multiple vulnerabilties have been found in yajl, a JSON parser / small
validating JSON generator# written in ANSI C, which potentially can
cause memory corruption or DoS.

The CVE-20117-16516 had been addressed already in ELA-888-1, 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.
