CVE-2019-12255 is an IPnet TCP/IP stack vulnerability in Wind River VxWorks, part of the URGENT/11 set. The flaw is triggered when the TCP component processes a segment with the TCP urgent pointer set to 0, leading to an integer underflow. According to the provided content, this underflow can propagate into a buffer overflow condition in applications that call recv(), recvfrom(), or recvmsg() on an affected socket. The issue affects the Interpeak IPnet stack used in VxWorks and other products that bundled IPnet. The content states that an attacker can exploit the flaw either by hijacking an existing TCP session and injecting crafted TCP segments or by establishing a new TCP session to any TCP port listened to by the target. Successful exploitation may crash the application reading from the socket and, in some cases, may lead to remote code execution.
