Resolution ========== Upgrade to 2019.05.12-1. # pacman -Syu "live-media>=2019.05.12-1" The problems have been fixed upstream in version 2019.05.12. Workaround ========== None. 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.
