It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2020-23545 and fix it if it is affected.\n\nWhat it is: CVE-2020-23545 is a high-severity memory corruption vulnerability in Irfanview Irfanview, published on 15 Dec 2021. 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-2020-23545 in the wild and no public exploit code.\n\nAffected product: Irfanview Irfanview. 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-2020-23545/ (Markdown: https://insights.sbomify.com/CVE-2020-23545/index.md)","id":"CVE-2020-23545","markdown":"https://insights.sbomify.com/CVE-2020-23545/index.md","name":"CVE-2020-23545","record":{"aliases":["GHSA-3mmp-fjhh-4r72"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Image viewer","requires_auth":"none","summary":"A write access violation in IrfanView's XPM parser allows attackers to execute arbitrary code or cause a denial of service via a crafted image file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"irfanview","vendor":"irfanview"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"IrfanView 4.54 allows a user-mode write access violation starting at FORMATS!ReadXPM_W+0x0000000000000531.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2020-23545","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"irfanview:irfanview","products":["irfanview:irfanview"],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2020-23546"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2020-23539"},"products":["n/a"],"published":"2021-12-15","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-1867","kev_date_added":null,"published":"2007-04-04"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2008-0493","kev_date_added":null,"published":"2008-01-30"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2007-1948","kev_date_added":null,"published":"2007-04-11"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2020-13905","kev_date_added":null,"published":"2020-06-10"},{"cvss_score":8.8,"headline":"Integer overflow in Irfanview","id":"CVE-2017-2813","kev_date_added":null,"published":"2017-06-21"},{"cvss_score":8.5,"headline":"Memory corruption in n/a","id":"CVE-2007-2363","kev_date_added":null,"published":"2007-04-30"},{"cvss_score":7.8,"headline":"IrfanView DWG File Parsing Out-Of-Bounds Read Remote Code Execution Vulnerability","id":"CVE-2024-11506","kev_date_added":null,"published":"2024-11-22"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A write access violation in IrfanView's XPM parser allows attackers to execute arbitrary code or cause a denial of service via a crafted image file.","url":"https://insights.sbomify.com/CVE-2020-23545/"}
