Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6961-1 advisory.

 It was discovered that BusyBox did not properly validate user input when performing certain arithmetic operations. If a user or automated system were tricked into processing a specially crafted file, an attacker could possibly use this issue to cause a denial of service, or execute arbitrary code.
 (CVE-2022-48174)

 It was discovered that BusyBox incorrectly managed memory when evaluating certain awk expressions. An attacker could possibly use this issue to cause a denial of service, or execute arbitrary code. This issue only affected Ubuntu 24.04 LTS. (CVE-2023-42363, CVE-2023-42364, CVE-2023-42365)
