affected by multiple vulnerabilities as referenced in the USN-7913-1 advisory.

    It was discovered that the stb library, included in MAME, had a

    heap-based buffer overflow. An attacker could possibly use this issue

    to crash the program or execute arbitrary code. (CVE-2018-16981)

    It was discovered that the tinyexr library, included in MAME, had a heap- based buffer over-read

    in the function DecodePixelData. An

    attacker could possibly use this issue to expose sensitive information or crash the program.
    (CVE-2022-34300)

    It was discovered that the expat library, included in MAME, had an integer-overflow in the function
    doProlog. An attacker could possibly use this issue to crash the program or execute arbitrary code.
    (CVE-2021-46143)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
