Description

According to the version of the gstreamer1-plugins-base packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  • GStreamer before 1.16.0 has a heap-based buffer overflow in the RTSP connection parser via a crafted response from a server, potentially allowing remote code execution.(CVE-2019-9928)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
