An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-14633 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-2018-14633/ (Markdown: https://insights.sbomify.com/CVE-2018-14633/index.md)","id":"CVE-2018-14633","markdown":"https://insights.sbomify.com/CVE-2018-14633/index.md","name":"CVE-2018-14633","record":{"aliases":["DEBIAN-CVE-2018-14633","GHSA-88p5-45fx-5x87","SUSE-SU-2018:3268-1","SUSE-SU-2018:3867-1","UBUNTU-CVE-2018-14633"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Linux kernel iSCSI","requires_auth":"none","summary":"Unauthenticated remote attackers can trigger a stack buffer overflow in the Linux kernel iSCSI target, causing denial of service or potential data exposure.","user_interaction":"not_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":"linux_kernel","vendor":"linux"},{"product":"enterprise_linux_eus","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"enterprise_linux_server_tus","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/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":"A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable.","ecosystems":["SUSE:Linux Enterprise Live Patching 12 SP3"],"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 kernel","id":"CVE-2018-14633","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","debian:debian_linux","linux:linux_kernel","redhat:enterprise_linux_eus","redhat:enterprise_linux_server","redhat:enterprise_linux_server_aus","redhat:enterprise_linux_server_tus","redhat:enterprise_linux_workstation"],"type":"memory_corruption","year":"2018"},"n_packages":3,"n_references":18,"next":{"headline":"Linux Kernel Integer Overflow","id":"CVE-2018-14634"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Live Patching 12 SP3","fixed":["2-2.1"],"introduced":["0"],"last_affected":[],"package":"kgraft-patch-SLE12-SP3_Update_18","purl":"pkg:rpm/suse/kgraft-patch-SLE12-SP3_Update_18\u0026distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2012%20SP3","source":"SUSE-SU-2018:3268-1"},{"ecosystem":"SUSE:Linux Enterprise Live Patching 12 SP3","fixed":["2-2.1"],"introduced":["0"],"last_affected":[],"package":"kgraft-patch-SLE12-SP3_Update_19","purl":"pkg:rpm/suse/kgraft-patch-SLE12-SP3_Update_19\u0026distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2012%20SP3","source":"SUSE-SU-2018:3268-1"},{"ecosystem":"SUSE:Linux Enterprise Live Patching 12 SP3","fixed":["2-2.1"],"introduced":["0"],"last_affected":[],"package":"kgraft-patch-SLE12-SP3_Update_20","purl":"pkg:rpm/suse/kgraft-patch-SLE12-SP3_Update_20\u0026distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2012%20SP3","source":"SUSE-SU-2018:3867-1"}],"prev":{"headline":"JSON-Patch Out-of-bounds Write vulnerability","id":"CVE-2018-14632"},"products":["kernel"],"published":"2018-09-25","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":"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["The Linux Foundation"]},"summary":"Unauthenticated remote attackers can trigger a stack buffer overflow in the Linux kernel iSCSI target, causing denial of service or potential data exposure.","url":"https://insights.sbomify.com/CVE-2018-14633/"}
