CVE-2024-47596: GHSL-2024-244: GStreamer has an OOB-read in FOURCC_SMI_ parsing

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 1.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-12-12 · updated 2026-06-17
• Weakness: CWE-125

Description

GStreamer is a library for constructing graphs of media-handling components. An OOB-read has been discovered in the qtdemux_parse_svq3_stsd_data function within qtdemux.c. In the FOURCC_SMI_ case, seqh_size is read from the input file without proper validation. If seqh_size is greater than the remaining size of the data buffer, it can lead to an OOB-read in the following call to gst_buffer_fill, which internally uses memcpy. This vulnerability can result in reading up to 4GB of process memory or potentially causing a segmentation fault (SEGV) when accessing invalid memory. This vulnerability is fixed in 1.24.10.

Affected products

• GStreamer: before 1.24.10 — fixed in 1.24.10

How to fix

Upgrade to a fixed version: GStreamer 1.24.10. Check the vendor advisory for mitigations.
