Details

Daisy Chen discovered that NASM was vulnerable to a heap buffer overflow when handling certain input. An attacker could possibly use this issue to cause NASM to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2023-31722)

It was discovered that NASM incorrectly handled memory allocation. An attacker could possibly use this issue to cause NASM to use excessive resources, leading to a denial of service. This issue only affected Ubuntu 24.04 LTS. (CVE-2021-33452, CVE-2021-33450)
