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-2020-27545 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-27545/ (Markdown: https://insights.sbomify.com/CVE-2020-27545/index.md)","id":"CVE-2020-27545","markdown":"https://insights.sbomify.com/CVE-2020-27545/index.md","name":"CVE-2020-27545","record":{"aliases":["AZL-33327","AZL-42093","DEBIAN-CVE-2020-27545","GHSA-9mh7-9qxg-6fpq","SUSE-SU-2023:2784-1","UBUNTU-CVE-2020-27545"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"DWARF debugging library","requires_auth":"none","summary":"An attacker can cause a denial of service via a crafted object triggering an out-of-bounds read in the libdwarf library.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libdwarf","vendor":"libdwarf_project"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-763","name":"Release of Invalid Pointer or Reference"}],"description":"libdwarf before 20201017 has a one-byte out-of-bounds read because of an invalid pointer dereference via an invalid line table in a crafted object.","ecosystems":["SUSE:Linux Enterprise Module for Package Hub 15 SP4","SUSE:Linux Enterprise Module for Package Hub 15 SP5","openSUSE:Leap 15.4","openSUSE:Leap 15.5"],"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":"Null dereference in n/a","id":"CVE-2020-27545","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2020"},"n_packages":4,"n_references":5,"next":{"headline":"Path traversal in n/a","id":"CVE-2020-27553"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Module for Package Hub 15 SP4","fixed":["20161124-150000.3.6.1"],"introduced":["0"],"last_affected":[],"package":"libdwarf","purl":"pkg:rpm/suse/libdwarf\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Package%20Hub%2015%20SP4","source":"SUSE-SU-2023:2784-1"},{"ecosystem":"SUSE:Linux Enterprise Module for Package Hub 15 SP5","fixed":["20161124-150000.3.6.1"],"introduced":["0"],"last_affected":[],"package":"libdwarf","purl":"pkg:rpm/suse/libdwarf\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Package%20Hub%2015%20SP5","source":"SUSE-SU-2023:2784-1"},{"ecosystem":"openSUSE:Leap 15.4","fixed":["20161124-150000.3.6.1"],"introduced":["0"],"last_affected":[],"package":"libdwarf","purl":"pkg:rpm/opensuse/libdwarf\u0026distro=openSUSE%20Leap%2015.4","source":"SUSE-SU-2023:2784-1"},{"ecosystem":"openSUSE:Leap 15.5","fixed":["20161124-150000.3.6.1"],"introduced":["0"],"last_affected":[],"package":"libdwarf","purl":"pkg:rpm/opensuse/libdwarf\u0026distro=openSUSE%20Leap%2015.5","source":"SUSE-SU-2023:2784-1"}],"prev":{"headline":"Code injection in n/a","id":"CVE-2020-27544"},"products":["n/a"],"published":"2023-04-15","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-9052","kev_date_added":null,"published":"2017-05-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-9054","kev_date_added":null,"published":"2017-05-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-9055","kev_date_added":null,"published":"2017-05-18"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2016-9558","kev_date_added":null,"published":"2017-02-28"},{"cvss_score":9.1,"headline":"Memory corruption in n/a","id":"CVE-2017-9053","kev_date_added":null,"published":"2017-05-18"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2016-9480","kev_date_added":null,"published":"2016-11-29"},{"cvss_score":8.1,"headline":"Memory corruption in n/a","id":"CVE-2022-34299","kev_date_added":null,"published":"2022-06-22"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-06","vendors":["n/a"]},"summary":"An attacker can cause a denial of service via a crafted object triggering an out-of-bounds read in the libdwarf library.","url":"https://insights.sbomify.com/CVE-2020-27545/"}
