sqfs_search_dir in Das U-Boot before 2025.01-rc1 exhibits an off-by-one error and resultant heap memory corruption for squashfs directory listing because the path separator is not considered in a size calculation.

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)

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4150 advisory.
