CVE-2019-14323
SSDP Responder 1.x through 1.5 mishandles incoming network messages, leading to a stack-based buffer overflow by 1 byte.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.65%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
SSDP Responder 1.x through 1.5 mishandles incoming network messages, leading to a stack-based buffer overflow by 1 byte. This results in a crash of the server, but only when strict stack checking is enabled. This is caused by an off-by-one error in ssdp_recv in ssdpd.c.
