It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-73433 in the wild and no public exploit code.\n\nAffected product: Gstreamer Gstreamer. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-73433/ (Markdown: https://insights.sbomify.com/CVE-2026-73433/index.md)","id":"CVE-2026-73433","markdown":"https://insights.sbomify.com/CVE-2026-73433/index.md","name":"CVE-2026-73433","record":{"aliases":["DEBIAN-CVE-2026-73433","ECHO-0929-81ea-1686","GHSA-cq86-v72j-qxrj","MINI-g8qx-q29m-9rcj","UBUNTU-CVE-2026-73433"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GStreamer multimedia framework","requires_auth":"none","summary":"An attacker can cause heap out-of-bounds read/write and application crash by tricking a user into opening a crafted AVI file with GStreamer.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"gstreamer","vendor":"gstreamer"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"}],"description":"A flaw was found in GStreamer gst-plugins-good (avidemux). When parsing FUJIFILM metadata in an AVI strd chunk, gst_avi_demux_parse_strd() decrements a remaining-length counter by fixed offsets (98 and 10 bytes) without verifying sufficient data remains. For crafted strd payloads of exactly 106 or 107 bytes, the counter underflows to a very large unsigned value, causing subsequent null-terminated string scanning to read far beyond the allocated heap buffer. Date-format normalization may also write beyond the buffer end. Confirmed impacts include heap out-of-bounds read, out-of-bounds write, heap information disclosure (adjacent data appearing in parsed metadata), and application crash/denial of service. The avidemux element is auto-plugged by playbin, decodebin, and gst-discoverer, so opening or previewing a crafted AVI is sufficient to trigger the issue. Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Integer overflow in Red Hat Enterprise Linux 10","id":"CVE-2026-73433","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gstreamer:gstreamer","products":["gstreamer:gstreamer","redhat:enterprise_linux"],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":15,"next":{"headline":"Gstreamer1-plugins-good: gstreamer: out-of-bounds read in avidemux vprp video field descriptor parsing","id":"CVE-2026-73434"},"packages":[],"prev":{"headline":"Server-side request forgery in vulnerability-lookup","id":"CVE-2026-73432"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 10.0 Extended Update Support","Red Hat Enterprise Linux 7 Extended Lifecycle Support","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support","Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On","Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support","Red Hat Enterprise Linux 8.6 Extended Update Support Long-Life Add-On","Red Hat Enterprise Linux 8.8 Telecommunications Update Service","Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions","Red Hat Enterprise Linux 9","Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions","Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions","Red Hat Enterprise Linux 9.6 Extended Update Support","gst-plugins-good"],"published":"2026-08-12","related":[{"cvss_score":8.8,"headline":"GStreamer rtpqdm2depay Out-Of-Bounds Write Remote Code Execution Vulnerability","id":"CVE-2026-3083","kev_date_added":null,"published":"2026-03-13"},{"cvss_score":8.8,"headline":"GStreamer rtpqdm2depay Heap-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2026-3085","kev_date_added":null,"published":"2026-03-13"},{"cvss_score":8.8,"headline":"GStreamer PGS File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2023-37328","kev_date_added":null,"published":"2024-05-03"},{"cvss_score":8.8,"headline":"GStreamer SRT File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2023-37329","kev_date_added":null,"published":"2024-05-03"},{"cvss_score":8.8,"headline":"GStreamer RealMedia File Parsing Integer Overflow Remote Code Execution Vulnerability","id":"CVE-2023-38103","kev_date_added":null,"published":"2024-05-03"},{"cvss_score":8.8,"headline":"GStreamer RealMedia File Parsing Integer Overflow Remote Code Execution Vulnerability","id":"CVE-2023-38104","kev_date_added":null,"published":"2024-05-03"},{"cvss_score":8.8,"headline":"GStreamer MXF File Parsing Integer Overflow Remote Code Execution Vulnerability","id":"CVE-2023-40474","kev_date_added":null,"published":"2024-05-03"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-23","vendors":["GStreamer","Red Hat"]},"summary":"An attacker can cause heap out-of-bounds read/write and application crash by tricking a user into opening a crafted AVI file with GStreamer.","url":"https://insights.sbomify.com/CVE-2026-73433/"}
