EUVDB-ID: #VU32105

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

Description

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.
