Description

• CVE-2019-7314 (arbitrary code execution)

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.

• CVE-2019-7733 (denial of service)

In Live555 0.95, a setup packet can cause a memory leak leading to DoS
because, when there are multiple instances of a single field (username,
realm, nonce, uri, or response), only the last instance can ever be
freed.

Impact

A remote attacker can cause a crash or execute arbitrary code on the
affected host via a crafted stream packet.
