Astra Linux - уязвимость в u-boot

An integer overflow occurs in the ext4fsreadsymlink function in Das U-Boot before version 2025.01-rc1. This issue arises due to the use of the zalloc function, which adds one to a le32 variable. This occurs through a crafted ext4 file system with an inode size of 0xffffffff. As a result, the mall...

grub2: Integer overflow in grub_ext2_read_link leads to heap-based buffer overflow

A flaw was found in grub2 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32MAX causes an arithmetic overflow, leading to a zero-sized memory allocation with a subsequent heap-based buffer overflow. The highest threat from this...
