Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The gst_riff_create_audio_caps function in gst-libs/gst/riff/riff-media.c in gst-plugins-base in GStreamer before 1.10.3 does not properly limit recursion, which allows remote attackers to cause a denial of service (stack overflow and crash) via vectors involving nested WAVEFORMATEX.

Mitigation

Install update from vendor's website.
