CVE-2020-10648

Integer overflows in memory allocation in Das U-Boot before version 2025.01-rc1 occur for a crafted squashfs filesystem. These issues can arise during the use of sbrk, request2size, or due to mishandling of ptrdiff_t on x86_64 architecture.

An integer overflow in ext4fs_read_symlink in Das U-Boot before version 2025.01-rc1 occurs during memory allocation for an ext4 filesystem with an inode size of 0xffffffff, resulting in a malloc of zero and memory overwrite.

Das U-Boot version 2022.01 has a Buffer Overflow vulnerability, which is different from the issue described in CVE-2022-30552.

Das U-Boot versions 2016.09 through 2019.07-rc4 can memset() too much data while reading a crafted ext4 filesystem, which results in a stack buffer overflow and likely code execution.

In Das U-Boot versions 2016.11-rc1 through 2019.07-rc4, an underflow can cause memcpy() to overwrite a very large amount of data, including the whole stack, while reading a crafted ext4 filesystem.

A crafted self-referential DOS partition table will cause all Das U-Boot versions through 2019.07-rc4 to infinitely recurse, leading to uncontrolled stack growth and eventually crashing or overwriting other data.

In Das U-Boot through version 2022.07-rc5, an integer signedness error and resultant stack-based buffer overflow in the 'i2c md' command enables the corruption of the return address pointer of the do_i2c_md function.

An issue was discovered in Das U-Boot through 2019.07. There is a stack-based buffer overflow in this nfs_handler reply helper function: nfs_umountall_reply.

An issue was discovered in Das U-Boot through 2019.07. There is a stack-based buffer overflow in this nfs_handler reply helper function: nfs_mount_reply.

An issue was discovered in Das U-Boot through 2019.07 related to a stack-based buffer overflow in the nfs_readlink_reply helper function.
