Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-1091 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-2011-1091/ (Markdown: https://insights.sbomify.com/CVE-2011-1091/index.md)","id":"CVE-2011-1091","markdown":"https://insights.sbomify.com/CVE-2011-1091/index.md","name":"CVE-2011-1091","record":{"aliases":["DEBIAN-CVE-2011-1091","GHSA-784h-wwvm-3rvx"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Pidgin instant messenger","requires_auth":"low_privilege","summary":"Remote attackers can crash Pidgin via malformed YMSG packets, causing denial of service for users of the instant messaging client.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"pidgin","vendor":"pidgin"}],"cvss":{"score":4,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:S/C:N/I:N/A:P","version":"2.0"},"cwes":[],"description":"libymsg.c in the Yahoo! protocol plugin in libpurple in Pidgin 2.6.0 through 2.7.10 allows (1) remote authenticated users to cause a denial of service (NULL pointer dereference and application crash) via a malformed YMSG notification packet, and allows (2) remote Yahoo! servers to cause a denial of service (NULL pointer dereference and application crash) via a malformed YMSG SMS message.","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-2011-1091","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":20,"next":{"headline":"Integer overflow in n/a","id":"CVE-2011-1092"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2011-1090"},"products":["n/a"],"published":"2011-03-14","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2013-6490","kev_date_added":null,"published":"2014-02-06"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2016-1000030","kev_date_added":null,"published":"2018-09-05"},{"cvss_score":9.3,"headline":"Command injection in n/a","id":"CVE-2013-6486","kev_date_added":null,"published":"2014-02-06"},{"cvss_score":9.3,"headline":"Command injection in n/a","id":"CVE-2011-3185","kev_date_added":null,"published":"2011-08-29"},{"cvss_score":9.3,"headline":"Integer overflow in n/a","id":"CVE-2009-1376","kev_date_added":null,"published":"2009-05-26"},{"cvss_score":9,"headline":"Command injection in n/a","id":"CVE-2007-3841","kev_date_added":null,"published":"2007-07-17"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2013-6487","kev_date_added":null,"published":"2014-02-06"}],"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 malformed YMSG packets, causing denial of service for users of the instant messaging client.","url":"https://insights.sbomify.com/CVE-2011-1091/"}
