Summary
yajl vulnerabilities
Details

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)
