Summary
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)
