Summary
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
checks in several functions, which could lead to a buffer overflow. An
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)
