An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2011-1547 exists.\n\nAffected product: Netbsd Netbsd. 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-2011-1547/ (Markdown: https://insights.sbomify.com/CVE-2011-1547/index.md)","id":"CVE-2011-1547","markdown":"https://insights.sbomify.com/CVE-2011-1547/index.md","name":"CVE-2011-1547","record":{"aliases":["GHSA-gm4v-77j4-2h42"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"NetBSD kernel","requires_auth":"none","summary":"Remote attackers can cause denial of service via crafted packets when IPsec is enabled in NetBSD kernels.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"netbsd","vendor":"netbsd"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Multiple stack consumption vulnerabilities in the kernel in NetBSD 4.0, 5.0 before 5.0.3, and 5.1 before 5.1.1, when IPsec is enabled, allow remote attackers to cause a denial of service (memory corruption and panic) or possibly have unspecified other impact via a crafted (1) IPv4 or (2) IPv6 packet with nested IPComp headers.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2011-04-01","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2011-04-01","kind":"exploitdb","ref":"17097","stars":null,"title":"IPComp - encapsulation Kernel Memory Corruption"}],"tier":"weaponised"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2011-1547","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"netbsd:netbsd","products":["netbsd:netbsd"],"type":"memory_corruption","year":"2011"},"n_packages":0,"n_references":3,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2011-1548"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2011-1546"},"products":["n/a"],"published":"2011-05-09","related":[{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2017-1000374","kev_date_added":null,"published":"2017-06-19"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-1000375","kev_date_added":null,"published":"2017-06-19"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2017-1000378","kev_date_added":null,"published":"2017-06-19"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2015-8212","kev_date_added":null,"published":"2017-01-19"},{"cvss_score":9.3,"headline":"Denial of service in n/a","id":"CVE-2008-3584","kev_date_added":null,"published":"2008-09-11"},{"cvss_score":9.3,"headline":"Security feature bypass in n/a","id":"CVE-2008-1335","kev_date_added":null,"published":"2008-03-13"},{"cvss_score":7.8,"headline":"Path traversal in n/a","id":"CVE-2016-6253","kev_date_added":null,"published":"2017-01-20"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service via crafted packets when IPsec is enabled in NetBSD kernels.","url":"https://insights.sbomify.com/CVE-2011-1547/"}
