What is CVE-2024-47538?
CVE-2024-47538 is a high-severity memory corruption vulnerability in Gstreamer Gstreamer, published on 11 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
GStreamer is a library for constructing graphs of media-handling components. A stack-buffer overflow has been detected in the `vorbis_handle_identification_packet` function within `gstvorbisdec.c`. The position array is a stack-allocated buffer of size 64. If vd->vi.channels exceeds 64, the for loop will write beyond the boundaries of the position array. The value written will always be `GST_AUDIO_CHANNEL_POSITION_NONE`. This vulnerability allows someone to overwrite the EIP address allocated in the stack. Additionally, this bug can overwrite the `GstAudioInfo` info structure. This vulnerability is fixed in 1.24.10.
Which versions are affected by CVE-2024-47538?
