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.

Weakness

A product calculates or uses an incorrect maximum or minimum value that is 1 more, or 1 less, than the correct value.
