CVE-2024-47538

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.

A flaw was found in the Vorbis decoder in the GStreamer library. Processing a specially crafted input file can cause a stack-based buffer overflow in the Vorbis decoder due to improper input validation, resulting in unexpected behavior or, most likely, an application crash.

An update for gstreamer1-plugins-base is now available for Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.6 Update Services for SAP Solutions, and Red Hat Enterprise Linux 8.6 Telecommunications Update Service. Issues addressed include buffer overflow and out of bounds write vulnerabilities.
