Описание
Integer overflow in the vmnc decoder in the gstreamer allows remote attackers to cause a denial of service (crash) via large width and height values, which triggers a buffer overflow.
An integer overflow flaw, leading to a heap-based buffer overflow, was found in GStreamer's VMware VMnc video file format decoding plug-in. A remote attacker could use this flaw to cause an application using GStreamer to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
Меры по смягчению последствий
This mitigation is only required if vulnerable gstreamer-plugins-bad-free and/or gstreamer1-plugins-bad-free packages are installed. For RHEL 7, sudo rm /usr/lib*/gstreamer-1.0/libgstvmnc.so sudo rm /usr/lib*/gstreamer-0.10/libgstvmnc.so For RHEL 6, sudo rm /usr/lib*/gstreamer-0.10/libgstvmnc.so Please note that this mitigation deletes the vulnerable VMware NC decoder, which removes the functionality to play VMware movie files.
