Package : yajl
Version : 2.1.0-3+deb10u2
CVE ID : CVE-2017-16516 CVE-2022-24795 CVE-2023-33460
Debian Bug : 1040036
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 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.
