high Nessus Plugin ID 299808

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8056-1 advisory.

 Simon Diepold discovered that U-Boot incorrectly handled certain DHCP responses. An attacker on the local network could possibly use this issue to obtain sensitive memory contents. (CVE-2024-42040)

 It was discovered that U-Boot incorrectly handled symlink size calculations in squashfs file systems. An attacker could use this issue with a specially crafted squashfs file system to cause U-Boot to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2024-57254)

 It was discovered that U-Boot incorrectly handled inode size calculations in squashfs file systems. An attacker could use this issue with a specially crafted squashfs file system to cause U-Boot to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2024-57255)

 It was discovered that U-Boot incorrectly handled inode size calculations in EXT4 file systems. An attacker could use this issue with a specially crafted EXT4 file system to cause U-Boot to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2024-57256)

 It was discovered that U-Boot incorrectly handled deep symlink nesting in squashfs file systems. An attacker could possibly use this issue with a specially crafted squashfs file system to cause U-Boot to crash, resulting in a denial of service. (CVE-2024-57257)

 It was discovered that U-Boot incorrectly handled memory allocation in squashfs file systems. An attacker could use this issue with a specially crafted squashfs file system to cause U-Boot to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2024-57258)

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.
