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-2012-5836 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. 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-2012-5836/ (Markdown: https://insights.sbomify.com/CVE-2012-5836/index.md)","id":"CVE-2012-5836","markdown":"https://insights.sbomify.com/CVE-2012-5836/index.md","name":"CVE-2012-5836","record":{"aliases":["GHSA-w8gr-r7vf-c9fc"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mozilla Firefox","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or crash the application by exploiting CSS and SVG text handling in Mozilla browsers.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"firefox","vendor":"mozilla"},{"product":"seamonkey","vendor":"mozilla"},{"product":"thunderbird","vendor":"mozilla"},{"product":"opensuse","vendor":"opensuse"},{"product":"linux_enterprise_desktop","vendor":"suse"},{"product":"linux_enterprise_server","vendor":"suse"},{"product":"linux_enterprise_software_development_kit","vendor":"suse"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Mozilla Firefox before 17.0, Thunderbird before 17.0, and SeaMonkey before 2.14 allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving the setting of Cascading Style Sheets (CSS) properties in conjunction with SVG text.","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":"Code injection in n/a","id":"CVE-2012-5836","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","mozilla:firefox","mozilla:seamonkey","mozilla:thunderbird","opensuse:opensuse","suse:linux_enterprise_desktop","suse:linux_enterprise_server","suse:linux_enterprise_software_development_kit"],"type":"code_injection","year":"2012"},"n_packages":0,"n_references":21,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2012-5837"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2012-5835"},"products":["n/a"],"published":"2012-11-21","related":[{"cvss_score":9.8,"headline":"SaltStack Salt Authentication Bypass","id":"CVE-2020-11651","kev_date_added":"2021-11-03","published":"2020-04-30"},{"cvss_score":9.8,"headline":"OpenSMTPD Remote Code Execution","id":"CVE-2020-7247","kev_date_added":"2022-03-25","published":"2020-01-29"},{"cvss_score":9.8,"headline":"Exim Out-of-bounds Write","id":"CVE-2019-16928","kev_date_added":"2022-03-03","published":"2019-09-27"},{"cvss_score":9.8,"headline":"Exim Buffer Overflow","id":"CVE-2018-6789","kev_date_added":"2021-11-03","published":"2018-02-08"},{"cvss_score":9.8,"headline":"Oracle Java SE and Java SE Embedded Remote Code Execution","id":"CVE-2015-2590","kev_date_added":"2022-03-03","published":"2015-07-16"},{"cvss_score":9.8,"headline":"Oracle JRE Remote Code Execution","id":"CVE-2013-0422","kev_date_added":"2022-05-25","published":"2013-01-10"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2011-3544","kev_date_added":"2022-03-03","published":"2011-10-19"}],"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 execute arbitrary code or crash the application by exploiting CSS and SVG text handling in Mozilla browsers.","url":"https://insights.sbomify.com/CVE-2012-5836/"}
