CVE-2024-57256
HighSummary
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.
Risk Assessment
The integer overflow can lead to memory overwrite, posing a risk of unauthorized code execution or system instability. Organizations should be aware of the potential threats associated with this vulnerability.
Recommendation
It is recommended to update Das U-Boot to version 2025.01-rc1 or later to mitigate this vulnerability. Additionally, monitoring and auditing systems using ext4 may help detect potential exploitation attempts.
Other vulnerabilities in Das U-Boot
See all- CVE-2024-57258High
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.
- CVE-2022-30790High
Das U-Boot version 2022.01 has a Buffer Overflow vulnerability, which is different from the issue described in CVE-2022-30552.
- CVE-2020-10648High
Das U-Boot through 2020.01 allows attackers to bypass verified boot restrictions and subsequently boot arbitrary images by providing a crafted FIT image to a system configured to boot the default configuration.
- CVE-2019-13106High
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.
- CVE-2019-13104High
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.
- CVE-2019-13103High
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.
- CVE-2022-34835Critical
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.
- CVE-2019-14204Critical
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.
- CVE-2019-14203Critical
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.
- CVE-2019-14202Critical
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.
Original NVD description (English source)
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 overwrite.
