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.
For Debian 8 jessie, these problems have been fixed in version 2.1.0-2+deb8u2.
For Debian 9 stretch, these problems have been fixed in version 2.1.0-2+deb9u2.
We recommend that you upgrade your yajl packages.
