• 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

• Weakness: CWE-191

Description

GStreamer is a library for constructing graphs of media-handling components. An integer underflow has been detected in extract_cc_from_data function within qtdemux.c. In the FOURCC_c708 case, the subtraction atom_length - 8 may result in an underflow if atom_length is less than 8. When that subtraction underflows, *cclen ends up being a large number, and then cclen is passed to g_memdup2 leading to an out-of-bounds (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.
