Overview
Affected versions of this package are vulnerable to Buffer Overflow in the udp_set_len_short process. An attacker can cause a system crash or potentially execute arbitrary code by sending a specially crafted large UDP packet when the IP_MTU_DISCOVER socket option is set to IP_PMTUDISC_PROBE and the network device has an unusually large MTU.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
