Product: GPAC (MP4Box) Affected: gpac/gpac prior to fix commit (see References) CVE: CVE-2025-60474 CWE: CWE-122 (Heap-based Buffer Overflow) CVSS 3.1: 4.3 MEDIUM (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L) Reporter: sigdevel <https://infosec.exchange/@sigdevel>

Description: The gfmediaimport() function in GPAC's media import layer (mediatools/mediaimport.c:1297) imports media tracks from input files into the filter processing pipeline. When MP4Box inspects a crafted MPEG-2 TS file, the function stores a property value that was produced by strdup(""), allocating a 1-byte heap buffer containing only the NUL terminator at address 0x502000003110.

The function subsequently reads 1 byte at offset [1] of this buffer (past its only valid index [0]) at address 0x502000003111, triggering a heap-buffer-overflow read and crashing the process (Denial of Service).

Crash is reproducible on the current master branch at the time of discovery. No authentication or special privileges required beyond ability to provide a crafted file.

Description: The gffilterinparentchain() function in GPAC's filter session core (filtercore/filterpid.c:2145) walks the filter parent chain to determine whether a given filter is an ancestor of another, and is called during PID initialization from gffilterpidinittask(). When MP4Box inspects a crafted MPEG-2 TS file containing corrupted PMT descriptors, reused PIDs, and malformed PES headers that produce an abnormal PID chain state, the function is reached with a NULL or uninitialized parent filter pointer.

The function dereferences the parent pointer without validating it, attempting a READ at address 0x000000000008 (null+0x8 field offset), resulting in a segmentation fault and process crash (Denial of Service).

Crash is reproducible on the current master branch at the time of discovery. No authentication or special privileges required beyond ability to provide a crafted file.

Description: The gffilterpidgetpacket() function in GPAC's filter session core (filtercore/filterpid.c:6827) retrieves the next available packet from a filter PID for processing by downstream filters such as the inspect filter. When MP4Box inspects a crafted MPEG-2 TS file with corrupted PMT descriptors and abnormal PCR discontinuities that drive the pipeline through PID deletion and re-enqueue paths, gffilterpiddel() frees the 336-byte PID instance at filtercore/filterpid.c:5933.

The inspect filter subsequently calls gffilterpidgetpacket() on the invalidated PID without checking whether the PID object has been released, performing a READ of 8 bytes at address 0x513000002dc0 (start of the freed allocation) and crashing the process (Denial of Service).

Description: The gffilterpidinstswap() function in GPAC's filter session core (filtercore/filterpid.c:633) swaps PID instance references during PID reconfiguration. When MP4Box inspects a crafted MPEG-2 TS file containing corrupted PMT descriptors and invalid stream configurations, the function frees the ctx->pidinst structure (a 336-byte allocation) at filtercore/filterpid.c:716 inside gffilterpidconfigure() but does not reset the pointer to NULL afterwards.

A subsequent code path within the same reconfiguration call dereferences the now-dangling ctx->pidinst pointer, performing a READ of 8 bytes at address 0x513000000598 (24 bytes inside the freed region), resulting in a heap-use-after-free and process crash (Denial of Service).

Description: The gffilterpidreconfiguretaskdiscard() function in GPAC's filter session core (filtercore/filterpid.c:1341) handles cleanup of filter PID reconfiguration tasks during media import.

The attack vector is: Local (AV:L): a local, authenticated user who processes a specially crafted MPEG-2 TS/MP4 file with MP4Box can trigger the bug during filter teardown (PID instance swap/delete), causing a crash. ¶¶ In GPAC s MP4Box, gffilterpidinstswapdeletetask() in filtercore/filterpid.c may dereference objects after they have been freed when cleaning up PID instances after a swap/delete operation.

Hi David,

On Mon, Jun 08, 2026 at 07:46:07PM -0400, David A. Wheeler wrote: All: I propose that we create a separate mailing list, say "oss-security-vulnerability-reports", for run-of-the-mill vulnerability reports about open source software (OSS). Run-of-the-mill reports would then go there and not to this mailing list "oss-security". This would leave this oss-security" mailing list for general discussions about the topic of OSS security, including discussions about specific publicly known vulnerabilities that are especially noteworthy in some way. Tools that want the full flood could monitor "oss-security-vulnerability-reports".

Here's my rationale.

In short: There are so many OSS projects that it's already dubious to have a single mailing list for OSS vulnerability reports. However, I believe the coming AI vulnpocalypse will make it completely absurd. If we don't do this, I think the human participants will need to unsubscribe from this list sooner or later, and that would be sad. Thank you for bringing this up.

I do indeed see the problem, but I don't like the proposal. Also, for now the increased volume on this list hasn't exceeded its historical pre-AI peak: we had 485 messages in October 2014, but 455 in May 2026. I'm not seeing a mass exodus of subscribers either. There's greater churn - more people are leaving, but at the same time more are joining.

Just by saying to no longer send run-of-the-mill vulnerability reports in here, we won't instantly achieve that. Sure the moderators can stop and re-route them, but that's not an easy job. It's tricky to draw the line between run-of-the-mill and noteworthy.

Rather than tell people to send something to the other list, I ask this:

Whenever practical, please group related vulnerability disclosures into fewer messages (like security advisories) and use helpful Subject lines. Include the project name in a fixed place near the beginning of Subject, and make the Subject specific to the one disclosure rather than generic shared between multiple disclosures.

Example problems:

We got 25 messages on GPAC/MP4Box vulnerabilities in June so far. The Subject lines for them have GPAC/MP4Box in various places after the vulnerability type, whereas someone getting through this would first care what project is affected (is it even relevant to them) and would likely want messages grouped by project - if they have to be separate messages. Ideally, it would be just 2 messages - one on June 1st disclosing 6 issues, and one today disclosing 19 issues.

Conversely, some projects do group related issues, but then what goes into the Subject? We just had another "OpenSSL Security Advisory" a few days ago. It's the same generic Subject line every time. I think it'd be preferable to include some identifying information in there, at least "OpenSSL Security Advisory [9th June 2026]" as the first line says. Many other projects get this right, e.g. with Subject lines containing fixed release version numbers or identifying numbers for advisories or lists of CVEs. This is NOT a dig at Eric Covener (Apache). In fact, I want to praise Eric Covener (Apache) for his effort Indeed.

I greatly appreciate that Apache projects post their CVE disclosures in here, but it does sometimes result in a lot of messages for the same project on the same day. Also sometimes individual CVEs are missed - like for the previous (not the latest) Apache httpd set of CVEs, I spent some time to ensure all were eventually brought in here, as initially some were not. If some CVE disclosures are similarly missed for a less popular Apache project, this would remain unnoticed (maybe already was).

I understand it took time and effort to get the current system working well, but maybe it's time for someone at Apache to start looking into updating the system to group CVE disclosures by project and release.

Ditto for Perl CPAN.
