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-2011-1951 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-2011-1951/ (Markdown: https://insights.sbomify.com/CVE-2011-1951/index.md)","id":"CVE-2011-1951","markdown":"https://insights.sbomify.com/CVE-2011-1951/index.md","name":"CVE-2011-1951","record":{"aliases":["DEBIAN-CVE-2011-1951","GHSA-7jqv-hh4c-ww3h"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"syslog-ng log server","requires_auth":"none","summary":"Remote attackers can cause denial of service via memory consumption in syslog-ng when specific global flags and PCRE versions are used.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"syslog-ng","vendor":"oneidentity"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"lib/logmatcher.c in Balabit syslog-ng before 3.2.4, when the global flag is set and when using PCRE 8.12 and possibly other versions, allows remote attackers to cause a denial of service (memory consumption) via a message that does not match a regular expression.","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":"Denial of service in n/a","id":"CVE-2011-1951","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2011"},"n_packages":0,"n_references":6,"next":{"headline":"Denial of service in n/a","id":"CVE-2011-1952"},"packages":[],"prev":{"headline":"Plone and plone.app.users allow remote authenticated users to modify the properties of arbitrary accounts","id":"CVE-2011-1950"},"products":["n/a"],"published":"2011-07-11","related":[{"cvss_score":9.3,"headline":"Other in n/a","id":"CVE-2008-5110","kev_date_added":null,"published":"2008-11-17"},{"cvss_score":7.7,"headline":"syslog-ng: Local privilege escalation from new to root in %post","id":"CVE-2020-8019","kev_date_added":null,"published":"2020-06-29"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2022-38725","kev_date_added":null,"published":"2023-01-23"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2002-1200","kev_date_added":null,"published":"2004-09-01"},{"cvss_score":6.9,"headline":"Misconfiguration in n/a","id":"CVE-2011-0343","kev_date_added":null,"published":"2011-01-28"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service via memory consumption in syslog-ng when specific global flags and PCRE versions are used.","url":"https://insights.sbomify.com/CVE-2011-1951/"}
