CVE-2017-20283
NXP MQX Classic before 5.0 contains an out-of-bounds write vulnerability in the RTCS UDP recvfrom() implementation.
Does this matter?
Lower severity and a low EPSS score (1.19%). Track it; it rarely justifies an emergency change on its own.
Description
NXP MQX Classic before 5.0 contains an out-of-bounds write vulnerability in the RTCS UDP recvfrom() implementation. Improper enforcement of the application-supplied receive buffer length may allow a crafted UDP packet to overflow the destination buffer, resulting in memory corruption, or denial of service.
