When parsing a Simple Index object, an attacker-controlled entry count is used to size a heap allocation without being limited to the payload available in the object. Processing a crafted ASF, WMV, or WMA file can cause a very large memory allocation request and lead to denial of service if the allocation fails or the process is memory-constrained.\n\n## Affected\n\n- `gstreamer1-plugins-ugly-free (all versions)`\n- `gstreamer1-plugins-ugly-free`\n- `gstreamer1-plugins-ugly-free`\n- `gstreamer1-plugins-ugly-free (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nAvoid opening untrusted ASF, WMV, or WMA files in GStreamer-based applications (including local players and media indexers/thumbnailers).","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
