Denx ≫ U-boot

Improper access control for volatile memory containing boot code in Universal Boot Loader (U-Boot) before 2017.11 and Qualcomm chips IPQ4019, IPQ5018, IPQ5322, IPQ6018, IPQ8064, IPQ8074, and IPQ9574 could allow an attacker to execute arbitrary code.

A lack of signature verification in the bootloader of DENX Software Engineering Das U-Boot (U-Boot) v1.1.3 allows attackers to install crafted firmware files, leading to arbitrary code execution.

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.

Integer overflows in memory allocation in Das U-Boot before 2025.01-rc1 occur for a crafted squashfs filesystem via sbrk, via request2size, or because ptrdiff_t is mishandled on x86_64.

A stack consumption issue in sqfs_size in Das U-Boot before 2025.01-rc1 occurs via a crafted squashfs filesystem with deep symlink nesting.

An integer overflow in ext4fs_read_symlink in Das U-Boot before 2025.01-rc1 occurs for zalloc (adding one to an le32 variable) via a crafted ext4 filesystem with an inode size of 0xffffffff, resulting in a malloc of zero and resultant memory overwrit...

An integer overflow in sqfs_resolve_symlink in Das U-Boot before 2025.01-rc1 occurs via a crafted squashfs filesystem with an inode size of 0xffffffff, resulting in a malloc of zero and resultant memory overwrite.

An integer overflow in sqfs_inode_size in Das U-Boot before 2025.01-rc1 occurs in the symlink size calculation via a crafted squashfs filesystem.

RAD SecFlow-2 devices with Hardware 0202, Firmware 4.1.01.63, and U-Boot 2010.12 allow URIs beginning with /.. for Directory Traversal, as demonstrated by reading /etc/shadow.

There exists an unchecked length field in UBoot. The U-Boot DFU implementation does not bound the length field in USB DFU download setup packets, and it does not verify that the transfer direction corresponds to the specified command. Consequently, i...
