Name of the Vulnerable Software and Affected Versions Live555 versions 1.08 and earlier

Description The issue arises from improper handling of MPEG-1 or 2 files. Specifically, sending two successive RTSP SETUP commands for the same track can cause a Use-After-Free condition, leading to a daemon crash.

Recommendations For versions 1.08 and earlier, consider disabling the RTSP SETUP command for the same track to prevent the Use-After-Free condition until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
