The updated live, mplayer, vlc packages fix security vulnerabilities:
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-2019-7314)
In Live555 before 2019.02.27, malformed headers lead to invalid memory access in the parseAuthorizationHeader function. (CVE-2019-9215)
Mplayer and VLC has been rebuilt against new live packages.
Also, VLC has been updated to version 3.0.6.
