libcurl.so is vulnerable to arbitrary code execution. A heap-based buffer overflow in the function tftp_receive_packet() that receives data from a TFTP server could potentially allow an attacker to execute arbitrary code by sending an OACK without the BLKSIZE option, when a BLKSIZE smaller than 512 bytes was requested by the TFTP client.
