CVE-2024-47545: GHSL-2024-242: GStreamer has an integer underflow in FOURCC_strf parsing leading to OOB-read

• 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-191

Description

GStreamer is a library for constructing graphs of media-handling components. An integer underflow has been detected in qtdemux_parse_trak function within qtdemux.c. During the strf parsing case, the subtraction size -= 40 can lead to a negative integer overflow if it is less than 40. If this happens, the subsequent call to gst_buffer_fill will invoke memcpy with a large tocopy size, resulting in an OOB-read. 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.
