DescriptionCVE.org

A use-after-free in the gf_filter_pid_inst_swap_delete_task function (/filter_core/filter_pid.c) of GPAC Project/MP4Box before 26.02.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted media file.

AnalysisAI

Denial of service in GPAC (libgpac/MP4Box) before 26.02.0 lets an attacker crash the application by feeding it a crafted media file that triggers a use-after-free in gf_filter_pid_inst_swap_delete_task within the filter-core PID handling code. Any pipeline or user that parses untrusted media through GPAC is affected, with publicly available proof-of-concept code, though no active exploitation has been reported and EPSS exploitation probability is low (0.17%, 6th percentile). Impact is limited to availability - there is no confidentiality or integrity loss per the CVSS vector.

Technical ContextAI

GPAC is a widely used open-source multimedia framework whose MP4Box tool and libgpac library handle muxing, demuxing and transcoding of MP4/ISOBMFF and many other container formats through an internal filter graph. The flaw is a CWE-416 Use-After-Free in src/filter_core/filter_pid.c: during PID (packet identifier) reconfiguration, gf_filter_pid_inst_swap_delete_task can operate on a filter PID instance whose memory has already been freed when a relink/detach is concurrently pending. The upstream fix (commit 976dacf65cb6986a4e4f350fb8d3ed0a17dc3a77) adds a guard so a destination is not relinked when a detach (pidinst->detach_pending) is already pending, preventing the freed instance from being reused. The CPE in the feed is a placeholder (cpe:2.3:a:n/a:n/a:*) and provides no usable product/version data, so affected-product identification rests on the GPAC issue/commit and the 'before 26.02.0' description.

RemediationAI

Upgrade GPAC/MP4Box to 26.02.0 or later, which includes the fix commit 976dacf65cb6986a4e4f350fb8d3ed0a17dc3a77 that guards against relinking a destination PID while a detach is pending (Vendor-released patch: 26.02.0; fix verifiable via the linked GPAC commit). If you cannot upgrade immediately, the practical compensating controls are to stop processing untrusted media with vulnerable builds: route untrusted/user-uploaded files through a different validated decoder, or sandbox/isolate MP4Box execution (run it as an unprivileged, resource-limited, restartable worker process) so a crash only kills the disposable worker rather than the host service - the trade-off is added pipeline complexity and latency. For server-side ingestion, restrict or queue file submission and add automatic restart/supervision so the DoS does not cause sustained outage. Track the upstream issue at https://github.com/gpac/gpac/issues/3286 and confirm your distribution has rebuilt against 26.02.0.
