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-2019-3822 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu 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-2019-3822/ (Markdown: https://insights.sbomify.com/CVE-2019-3822/index.md)","id":"CVE-2019-3822","markdown":"https://insights.sbomify.com/CVE-2019-3822/index.md","name":"CVE-2019-3822","record":{"aliases":["ALPINE-CVE-2019-3822","CLEANSTART-2026-IB97779","CURL-CVE-2019-3822","DEBIAN-CVE-2019-3822","GHSA-8wr2-mqj7-7vxp","UBUNTU-CVE-2019-3822"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"curl library","requires_auth":"none","summary":"A stack-based buffer overflow in libcurl's NTLM authentication allows remote attackers to execute arbitrary code or cause denial of service via malicious server responses.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"libcurl","vendor":"haxx"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"clustered_data_ontap","vendor":"netapp"},{"product":"oncommand_insight","vendor":"netapp"},{"product":"oncommand_workflow_automation","vendor":"netapp"},{"product":"snapcenter","vendor":"netapp"},{"product":"communications_operations_monitor","vendor":"oracle"},{"product":"enterprise_manager_ops_center","vendor":"oracle"},{"product":"http_server","vendor":"oracle"},{"product":"mysql_server","vendor":"oracle"},{"product":"secure_global_desktop","vendor":"oracle"},{"product":"services_tools_bundle","vendor":"oracle"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"sinema_remote_connect_client","vendor":"siemens"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large 'nt response' data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large value' needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.","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 curl","id":"CVE-2019-3822","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","debian:debian_linux","haxx:libcurl","netapp:active_iq_unified_manager","netapp:clustered_data_ontap","netapp:oncommand_insight","netapp:oncommand_workflow_automation","netapp:snapcenter","oracle:enterprise_manager_ops_center","oracle:http_server","oracle:mysql_server","redhat:enterprise_linux"],"type":"memory_corruption","year":"2019"},"n_packages":0,"n_references":15,"next":{"headline":"Memory corruption in curl","id":"CVE-2019-3823"},"packages":[],"prev":{"headline":"Denial of service in ceph","id":"CVE-2019-3821"},"products":["curl"],"published":"2019-02-06","related":[{"cvss_score":9.8,"headline":"SaltStack Salt Authentication Bypass","id":"CVE-2020-11651","kev_date_added":"2021-11-03","published":"2020-04-30"},{"cvss_score":9.8,"headline":"OpenSMTPD Remote Code Execution","id":"CVE-2020-7247","kev_date_added":"2022-03-25","published":"2020-01-29"},{"cvss_score":9.8,"headline":"Exim Out-of-bounds Write","id":"CVE-2019-16928","kev_date_added":"2022-03-03","published":"2019-09-27"},{"cvss_score":9.8,"headline":"Exim Buffer Overflow","id":"CVE-2018-6789","kev_date_added":"2021-11-03","published":"2018-02-08"},{"cvss_score":9.8,"headline":"Oracle Java SE and Java SE Embedded Remote Code Execution","id":"CVE-2015-2590","kev_date_added":"2022-03-03","published":"2015-07-16"},{"cvss_score":9.8,"headline":"Oracle JRE Remote Code Execution","id":"CVE-2013-0422","kev_date_added":"2022-05-25","published":"2013-01-10"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2011-3544","kev_date_added":"2022-03-03","published":"2011-10-19"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-15","vendors":["The curl Project"]},"summary":"A stack-based buffer overflow in libcurl's NTLM authentication allows remote attackers to execute arbitrary code or cause denial of service via malicious server responses.","url":"https://insights.sbomify.com/CVE-2019-3822/"}
