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-2009-1959 exists.\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-2009-1959/ (Markdown: https://insights.sbomify.com/CVE-2009-1959/index.md)","id":"CVE-2009-1959","markdown":"https://insights.sbomify.com/CVE-2009-1959/index.md","name":"CVE-2009-1959","record":{"aliases":["DEBIAN-CVE-2009-1959","GHSA-2v73-9rwq-75qc"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IRC client","requires_auth":"none","summary":"Remote IRC servers can crash the irssi client via an off-by-one error in event handling, causing a denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"irssi","vendor":"irssi"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"Off-by-one error in the event_wallops function in fe-common/irc/fe-events.c in irssi 0.8.13 allows remote IRC servers to cause a denial of service (crash) via an empty command, which triggers a one-byte buffer under-read and a one-byte buffer underflow.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2009-05-15","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2009-05-15","kind":"exploitdb","ref":"33041","stars":null,"title":"Irssi 0.8.13 - 'WALLOPS' Message Off-by-One Heap Memory Corruption"}],"tier":"weaponised"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2009-1959","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2009"},"n_packages":0,"n_references":15,"next":{"headline":"Code injection in n/a","id":"CVE-2009-1960"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2009-1958"},"products":["n/a"],"published":"2009-06-06","related":[{"cvss_score":10,"headline":"Hardcoded credentials in n/a","id":"CVE-2002-1840","kev_date_added":null,"published":"2005-06-28"},{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2017-10965","kev_date_added":null,"published":"2017-07-07"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2017-10966","kev_date_added":null,"published":"2017-07-07"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2017-7191","kev_date_added":null,"published":"2017-03-27"},{"cvss_score":9.3,"headline":"Command injection in n/a","id":"CVE-2007-4396","kev_date_added":null,"published":"2007-08-18"},{"cvss_score":8.1,"headline":"Use after free in n/a","id":"CVE-2019-13045","kev_date_added":null,"published":"2019-06-29"},{"cvss_score":7.5,"headline":"Use after free in n/a","id":"CVE-2017-15227","kev_date_added":null,"published":"2017-10-22"}],"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":"2024-08-07","vendors":["n/a"]},"summary":"Remote IRC servers can crash the irssi client via an off-by-one error in event handling, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2009-1959/"}
