liblivemedia in Live555 before 2019.02.03 mishandles the termination of an RTSP stream after RTP/RTCP-over-RTSP has been set up, which could lead to a Use-After-Free error that causes the RTSP server to crash (Segmentation fault) or possibly have unspecified other impact.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
