Summary
u-boot vulnerabilities
Details

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)
