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-2017-6891 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2017-6891/ (Markdown: https://insights.sbomify.com/CVE-2017-6891/index.md)","id":"CVE-2017-6891","markdown":"https://insights.sbomify.com/CVE-2017-6891/index.md","name":"CVE-2017-6891","record":{"aliases":["ALPINE-CVE-2017-6891","DEBIAN-CVE-2017-6891","DLA-950-1","DSA-3861-1","GHSA-ch46-3x6h-7qrw","MGASA-2017-0159","UBUNTU-CVE-2017-6891","USN-3309-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GnuTLS libtasn1 library","requires_auth":"none","summary":"A stack-based buffer overflow in libtasn1 allows attackers to execute arbitrary code or cause denial of service via a crafted assignments file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"flexera","cpe":[{"product":"bookkeeper","vendor":"apache"},{"product":"debian_linux","vendor":"debian"},{"product":"libtasn1","vendor":"gnu"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Two errors in the \"asn1_find_node()\" function (lib/parser_aux.c) within GnuTLS libtasn1 version 4.10 can be exploited to cause a stacked-based buffer overflow by tricking a user into processing a specially crafted assignments file via the e.g. asn1Coding utility.","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":"Memory corruption in GnuTLS libtasn1","id":"CVE-2017-6891","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux"],"type":"memory_corruption","year":"2017"},"n_packages":0,"n_references":10,"next":{"headline":"Memory corruption in libsndfile","id":"CVE-2017-6892"},"packages":[],"prev":{"headline":"Memory corruption in LibRaw-demosaic-pack-GPL2","id":"CVE-2017-6890"},"products":["GnuTLS libtasn1"],"published":"2017-05-22","related":[{"cvss_score":9.8,"headline":"Deserialization of Untrusted Data in Log4j","id":"CVE-2019-17571","kev_date_added":null,"published":"2019-12-20"},{"cvss_score":7.5,"headline":"A flaw was discovered in OpenLDAP before 2.4.57 leading in an assertion failure in slapd in the X.509 DN parsing in decode.c ber_next_elemen","id":"CVE-2020-36230","kev_date_added":null,"published":"2021-01-25"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2019-19906","kev_date_added":null,"published":"2019-12-19"},{"cvss_score":7.1,"headline":"Memory corruption in n/a","id":"CVE-2020-23922","kev_date_added":null,"published":"2021-04-21"},{"cvss_score":5.9,"headline":"Apache BookKeeper: Java Client Uses Connection to Host that Failed Hostname Verification","id":"CVE-2022-32531","kev_date_added":null,"published":"2022-12-15"},{"cvss_score":5.3,"headline":"Other in n/a","id":"CVE-2019-19924","kev_date_added":null,"published":"2019-12-24"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["Flexera Software LLC"]},"summary":"A stack-based buffer overflow in libtasn1 allows attackers to execute arbitrary code or cause denial of service via a crafted assignments file.","url":"https://insights.sbomify.com/CVE-2017-6891/"}
