------------------------------------------------------------------------- Debian LTS Advisory DLA-3492-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Tobias Frost July 11, 2023 https://wiki.debian.org/LTS ------------------------------------------------------------------------- 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.
