referenced in the USN-6413-1 advisory.

    It was discovered that GNU binutils was not properly performing checks when dealing with memory allocation
    operations, which could lead to excessive memory consumption. An attacker could possibly use this issue to
    cause a denial of service. This issue only affected Ubuntu 14.04 LTS. (CVE-2017-17122, CVE-2017-8421)

    It was discovered that GNU binutils was not properly performing bounds checks when processing debug
    sections with objdump, which could lead to an overflow. An attacker could possibly use this issue to cause
    a denial of service or execute arbitrary code. This issue only affected Ubuntu 14.04 LTS. (CVE-2018-20671,
    CVE-2018-6543)

    It was discovered that GNU binutils contained a reachable assertion, which could lead to an intentional
    assertion failure when processing certain crafted DWARF files. An attacker could possibly use this issue
    to cause a denial of service. This issue only affected Ubuntu 18.04 LTS. (CVE-2022-35205)

    It was discovered that GNU binutils incorrectly handled memory management operations in several of its
    functions, which could lead to excessive memory consumption due to memory leaks. An attacker could
    possibly use these issues to cause a denial of service. (CVE-2022-47007, CVE-2022-47008, CVE-2022-47010,
    CVE-2022-47011)

    It was discovered that GNU binutils was not properly performing bounds checks when dealing with memory
    allocation operations, which could lead to excessive memory consumption. An attacker could possibly use
    this issue to cause a denial of service. (CVE-2022-48063)
