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.
