The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6581-1 advisory.

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-2022-44840, CVE-2022-45703)

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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
