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-2011-2943 in the wild and no public exploit code.\n\nAffected product: Pidgin Pidgin. 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-2011-2943/ (Markdown: https://insights.sbomify.com/CVE-2011-2943/index.md)","id":"CVE-2011-2943","markdown":"https://insights.sbomify.com/CVE-2011-2943/index.md","name":"CVE-2011-2943","record":{"aliases":["DEBIAN-CVE-2011-2943","GHSA-39wr-cgvv-f2w7"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Pidgin IRC plugin","requires_auth":"none","summary":"Remote attackers can crash Pidgin via crafted IRC nicknames, requiring user interaction to trigger the denial of service.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"libpurple","vendor":"pidgin"},{"product":"pidgin","vendor":"pidgin"}],"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":[],"description":"The irc_msg_who function in msgs.c in the IRC protocol plugin in libpurple 2.8.0 through 2.9.0 in Pidgin before 2.10.0 does not properly validate characters in nicknames, which allows user-assisted remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted nickname that is not properly handled in a WHO response.","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":"Null dereference in n/a","id":"CVE-2011-2943","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"pidgin:pidgin","products":["pidgin:pidgin"],"type":"null_dereference","year":"2011"},"n_packages":0,"n_references":12,"next":{"headline":"SQL injection in n/a","id":"CVE-2011-2944"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2011-2942"},"products":["n/a"],"published":"2011-08-29","related":[{"cvss_score":5,"headline":"Null dereference in n/a","id":"CVE-2009-2703","kev_date_added":null,"published":"2009-09-08"},{"cvss_score":5,"headline":"Null dereference in n/a","id":"CVE-2009-3083","kev_date_added":null,"published":"2009-09-08"},{"cvss_score":5,"headline":"The msn_slp_process_msg function in libpurple/protocols/msn/slpcall.c in the MSN protocol plugin in libpurple 2.6.0 and 2.6.1, as used in Pi","id":"CVE-2009-3084","kev_date_added":null,"published":"2009-09-08"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2009-3085","kev_date_added":null,"published":"2009-09-08"},{"cvss_score":4.3,"headline":"Memory corruption in n/a","id":"CVE-2011-3594","kev_date_added":null,"published":"2011-11-04"},{"cvss_score":4,"headline":"directconn.c in the MSN protocol plugin in libpurple 2.7.6 through 2.7.8 in Pidgin before 2.7.9 allows remote authenticated users to cause a","id":"CVE-2010-4528","kev_date_added":null,"published":"2011-01-07"}],"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":"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 crash Pidgin via crafted IRC nicknames, requiring user interaction to trigger the denial of service.","url":"https://insights.sbomify.com/CVE-2011-2943/"}
