Details

It was discovered that GNU binutils incorrectly handled checks for memory
allocation when parsing relocs in a corrupt file. An attacker could possibly
use this issue to cause a denial of service. (CVE-2017-17122)

It was discovered that GNU binutils incorrectly handled certain corrupt DWARF
debug sections. An attacker could possibly use this issue to cause GNU
binutils to consume memory, resulting in a denial of service. (CVE-2021-3487)

It was discovered that GNU binutils incorrectly performed bounds checking
operations when parsing stabs debugging information. An attacker could
possibly use this issue to cause a denial of service or execute arbitrary
code. (CVE-2021-45078)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.04

In general, a standard system update will make all the necessary changes.
