grub2: Integer overflow in grub_squash_read_symlink may lead to heap-based buffer overflow

A flaw was found in grub2. When handling squashfs filesystems containing a symbolic link with name length of UINT32 bytes in size, the name size leads to an arithmetic overflow leading to a zero-size allocation further causing a heap-based buffer overflow with attacker controlled data. The highes...
