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: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-23457 exists.\n\nAffected product: Fedoraproject Fedora. 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-2023-23457/ (Markdown: https://insights.sbomify.com/CVE-2023-23457/index.md)","id":"CVE-2023-23457","markdown":"https://insights.sbomify.com/CVE-2023-23457/index.md","name":"CVE-2023-23457","record":{"aliases":["DEBIAN-CVE-2023-23457","GHSA-qcvq-w335-8gh3","UBUNTU-CVE-2023-23457","openSUSE-SU-2023:0031-1","openSUSE-SU-2024:12613-1"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"UPX executable packer","requires_auth":"none","summary":"An attacker can cause a denial of service in UPX by providing a crafted ELF file that triggers a segmentation fault during processing.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fedora","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"upx","vendor":"upx"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A Segmentation fault was found in UPX in PackLinuxElf64::invert_pt_dynamic() in p_lx_elf.cpp. An attacker with a crafted input file allows invalid memory address access that could lead to a denial of service.","ecosystems":["SUSE:Package Hub 15 SP4","openSUSE:Leap 15.4","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Upx: segv on packlinuxelf64::invert_pt_dynamic() in p_lx_elf.cpp","id":"CVE-2023-23457","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"denial_of_service","year":"2023"},"n_packages":3,"n_references":5,"next":{"headline":"Sunell DVR – Exposure of Sensitive Information","id":"CVE-2023-23458"},"packages":[{"ecosystem":"SUSE:Package Hub 15 SP4","fixed":["4.0.1-bp154.4.3.1"],"introduced":["0"],"last_affected":[],"package":"upx","purl":"pkg:rpm/suse/upx\u0026distro=SUSE%20Package%20Hub%2015%20SP4","source":"openSUSE-SU-2023:0031-1"},{"ecosystem":"openSUSE:Leap 15.4","fixed":["4.0.1-bp154.4.3.1"],"introduced":["0"],"last_affected":[],"package":"upx","purl":"pkg:rpm/opensuse/upx\u0026distro=openSUSE%20Leap%2015.4","source":"openSUSE-SU-2023:0031-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["4.0.1-2.1"],"introduced":["0"],"last_affected":[],"package":"upx","purl":"pkg:rpm/opensuse/upx\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:12613-1"}],"prev":{"headline":"Upx: heap-buffer-overflow in packtmt::pack()","id":"CVE-2023-23456"},"products":["fedoraproject:fedora","upx:upx"],"published":"2023-01-12","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-07","vendors":["fedoraproject","upx"]},"summary":"An attacker can cause a denial of service in UPX by providing a crafted ELF file that triggers a segmentation fault during processing.","url":"https://insights.sbomify.com/CVE-2023-23457/"}
