radare2 is vulnerable to Denial of Service (DoS) attacks. The vulnerability exists in the r_read_le32 function in the radare2 codebase. The function is responsible for reading a 32-bit integer from a memory buffer. The vulnerability occurs when the function fails to properly check the size of the buffer which can allow an attacker to overflow the buffer.
