An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2016-1923 in the wild and no public exploit code.\n\nAffected product: Uclouvain Openjpeg. 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-2016-1923/ (Markdown: https://insights.sbomify.com/CVE-2016-1923/index.md)","id":"CVE-2016-1923","markdown":"https://insights.sbomify.com/CVE-2016-1923/index.md","name":"CVE-2016-1923","record":{"aliases":["DEBIAN-CVE-2016-1923","GHSA-6h2h-qgx7-79mr","SUSE-SU-2019:2152-1","UBUNTU-CVE-2016-1923"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenJPEG library","requires_auth":"none","summary":"Remote attackers can cause a denial of service via a crafted JPEG 2000 image due to a heap-based buffer overflow in OpenJPEG.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"openjpeg","vendor":"uclouvain"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Heap-based buffer overflow in the opj_j2k_update_image_data function in OpenJpeg 2016.1.18 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted JPEG 2000 image.","ecosystems":["SUSE:Linux Enterprise Desktop 12 SP4","SUSE:Linux Enterprise Server 12 SP4","SUSE:Linux Enterprise Server for SAP Applications 12 SP4"],"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":"Memory corruption in n/a","id":"CVE-2016-1923","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"uclouvain:openjpeg","products":["uclouvain:openjpeg"],"type":"memory_corruption","year":"2016"},"n_packages":3,"n_references":4,"next":{"headline":"Denial of service in n/a","id":"CVE-2016-1924"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Desktop 12 SP4","fixed":["2.1.0-4.12.2"],"introduced":["0"],"last_affected":[],"package":"openjpeg2","purl":"pkg:rpm/suse/openjpeg2\u0026distro=SUSE%20Linux%20Enterprise%20Desktop%2012%20SP4","source":"SUSE-SU-2019:2152-1"},{"ecosystem":"SUSE:Linux Enterprise Server 12 SP4","fixed":["2.1.0-4.12.2"],"introduced":["0"],"last_affected":[],"package":"openjpeg2","purl":"pkg:rpm/suse/openjpeg2\u0026distro=SUSE%20Linux%20Enterprise%20Server%2012%20SP4","source":"SUSE-SU-2019:2152-1"},{"ecosystem":"SUSE:Linux Enterprise Server for SAP Applications 12 SP4","fixed":["2.1.0-4.12.2"],"introduced":["0"],"last_affected":[],"package":"openjpeg2","purl":"pkg:rpm/suse/openjpeg2\u0026distro=SUSE%20Linux%20Enterprise%20Server%20for%20SAP%20Applications%2012%20SP4","source":"SUSE-SU-2019:2152-1"}],"prev":{"headline":"Null dereference in n/a","id":"CVE-2016-1922"},"products":["n/a"],"published":"2016-01-27","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2013-4289","kev_date_added":null,"published":"2014-04-18"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2013-4290","kev_date_added":null,"published":"2014-04-18"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2012-3358","kev_date_added":null,"published":"2012-07-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2018-7648","kev_date_added":null,"published":"2018-03-02"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-17479","kev_date_added":null,"published":"2017-12-08"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2012-1499","kev_date_added":null,"published":"2012-04-11"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2018-16375","kev_date_added":null,"published":"2018-09-03"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service via a crafted JPEG 2000 image due to a heap-based buffer overflow in OpenJPEG.","url":"https://insights.sbomify.com/CVE-2016-1923/"}
