It was discovered that a memory leak existed in certain GNU binutils

modules. An attacker could possibly use this issue to cause a denial of

service (memory exhaustion). (CVE-2020-19724, CVE-2020-21490)

It was discovered that GNU binutils was not properly performing bounds

attacker could possibly use this issue to cause a denial of service,

expose sensitive information or execute arbitrary code.

(CVE-2020-19726, CVE-2021-46174, CVE-2022-45703)

It was discovered that GNU binutils was not properly initializing heap

memory when processing certain print instructions. An attacker could

possibly use this issue to expose sensitive information. (CVE-2020-35342)

It was discovered that GNU binutils was not properly handling the logic

behind certain memory management related operations, which could lead to a

buffer overflow. An attacker could possibly use this issue to cause a

denial of service or execute arbitrary code. (CVE-2022-44840)

It was discovered that GNU binutils was not properly handling the logic

behind certain memory management related operations, which could lead to

an invalid memory access. An attacker could possibly use this issue to

cause a denial of service. (CVE-2022-47695)
