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-2007-4996 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-2007-4996/ (Markdown: https://insights.sbomify.com/CVE-2007-4996/index.md)","id":"CVE-2007-4996","markdown":"https://insights.sbomify.com/CVE-2007-4996/index.md","name":"CVE-2007-4996","record":{"aliases":["DEBIAN-CVE-2007-4996","GHSA-r9v7-jgpj-m4mq"],"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":"none","summary":"Remote attackers can crash Pidgin by sending MSN nudge messages to users not on their buddy list, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"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":"libpurple in Pidgin before 2.2.1 does not properly handle MSN nudge messages from users who are not on the receiver's buddy list, which allows remote attackers to cause a denial of service (crash) via a nudge message that triggers an access of \"an invalid memory location.\"","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-2007-4996","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"pidgin:pidgin","products":["pidgin:pidgin"],"type":"denial_of_service","year":"2007"},"n_packages":0,"n_references":9,"next":{"headline":"Integer underflow in the ieee80211_rx function in net/ieee80211/ieee80211_rx.c in the Linux kernel 2.6.x before 2.6.23 allows remote attacke","id":"CVE-2007-4997"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2007-4995"},"products":["n/a"],"published":"2007-10-01","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":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can crash Pidgin by sending MSN nudge messages to users not on their buddy list, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2007-4996/"}
