USN-6233-1 fixed vulnerabilities in YAJL. This update provides the
corresponding updates for Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu
23.04.
Original advisory details:
It was discovered that YAJL was not properly performing bounds checks when
decoding a string with escape sequences. If a user or automated system
using YAJL were tricked into processing specially crafted input, an
attacker could possibly use this issue to cause a denial of service
(application abort). (CVE-2017-16516)
It was discovered that YAJL was not properly handling memory allocation
when dealing with large inputs, which could lead to heap memory
corruption. If a user or automated system using YAJL were tricked into
running a specially crafted large input, an attacker could possibly use
this issue to cause a denial of service. (CVE-2022-24795)
It was discovered that memory leaks existed in one of the YAJL parsing
functions. An attacker could possibly use this issue to cause a denial of
service (memory exhaustion). (CVE-2023-33460)
