Application crash via zero audio channel count
Published May 14, 2026 · Updated May 14, 2026
Divide by zero in GStreamer Good Plug-ins before 1.28.2 allows local users to crash applications by supplying a crafted MP4 audio track. The isomp4 qtdemux_audio_caps function accepts a zero audio-channel count from chan or chnl atom data and uses it as a divisor while building audio capabilities. Processing attacker-controlled MP4 content through an application that invokes this demuxer is required, and exploitation interrupts only that application process.
