CVE-2025-52292HIGH 7.5Real · low riskEPSS 1%
A stack buffer overflow in the filein_process function (in_file.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file.
CVE-2025-52293HIGH 7.5Real · low riskEPSS 0%
A segmentation violaton in the gf_hevc_read_sps_bs_internal function (media_tools/av_parsers.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying crafted HEVC SPS data.
CVE-2025-55657HIGH 7.5Real · low riskEPSS 0%
A NULL pointer dereference in the gf_odf_vvc_cfg_write_bs function (odf/descriptors.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file.
CVE-2025-55639MED 6.5EPSS 0%
GPAC MP4Box v2.4 was discovered to contain a NULL pointer dereference in the gf_isom_add_track_kind() function at isomedia/isom_write.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted MP4 file.
CVE-2025-55659MED 6.5EPSS 0%
A NULL pointer dereference in the ctts_box_write function (isomedia/box_code_base.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file.
CVE-2025-55658MED 6.5EPSS 0%
GPAC MP4Box v2.4 was discovered to contain a floating point exception in the gf_opus_parse_packet_header function (media_tools/av_parsers.c). bThis vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted MP4 file.
CVE-2025-55651MED 5.5EPSS 0%
A NULL pointer dereference in the gf_isom_get_user_data_count function (isomedia/isom_read.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file.
CVE-2026-9572LOW 3.3EPSS 0%
A security vulnerability has been detected in GPAC up to 2.4.0. Affected by this issue is the function Media_GetSample of the file src/isomedia/media.c of the component MP4Box. Such manipulation of the argument cat leads to memory leak. The attack can only be performed from a local environment. The exploit has been disclosed publicly and may be used. The name of the patch is e79c5cbe8b3fed27f4854ec229457d30c96206f1. It is best practice to apply a patch to resolve this issue.
CVE-2025-60465MED 6.1EPSS 0%
A use-after-free in the gf_filter_pid_inst_swap 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.
CVE-2025-60468MED 5.5EPSS 0%
GPAC Multimedia Open Source Project GPAC Project/MP4Box 2.5-DEV-rev1593-gfe88c3545-master is affected by: Buffer Overflow. The impact is: cause a denial of service (local). The component is: filter_core/filter_pid.c (L:574-580): function gf_filter_pid_inst_swap_delete_task() improperly accesses freed objects during PID instance swap/delete cleanup, leading to heap use-after-free. 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, gf_filter_pid_inst_swap_delete_task() in filter_core/filter_pid.c may dereference objects after they have been freed when cleaning up PID instances after a swap/delete operation. Crafted inputs (e.g., malformed MPEG-2 TS) can trigger a heap use-after-free and crash; exploitation may be possible.
