An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2005-2871 exists.\n\nAffected product: Mozilla Firefox. 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-2005-2871/ (Markdown: https://insights.sbomify.com/CVE-2005-2871/index.md)","id":"CVE-2005-2871","markdown":"https://insights.sbomify.com/CVE-2005-2871/index.md","name":"CVE-2005-2871","record":{"aliases":["DSA-837-1","GHSA-h4c5-jq2c-gq8v","RHSA-2005:768"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mozilla Firefox browser","requires_auth":"none","summary":"Remote attackers can trigger a buffer overflow in Firefox IDN handling via crafted hostnames, potentially executing arbitrary code or causing a crash.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"firefox","vendor":"mozilla"}],"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":[],"description":"Buffer overflow in the International Domain Name (IDN) support in Mozilla Firefox 1.0.6 and earlier, and Netscape 8.0.3.3 and 7.2, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a hostname with all \"soft\" hyphens (character 0xAD), which is not properly handled by the NormalizeIDN call in nsStandardURL::BuildNormalizedSpec.","ecosystems":["Red Hat:enterprise_linux:4::as","Red Hat:enterprise_linux:4::desktop","Red Hat:enterprise_linux:4::es","Red Hat:enterprise_linux:4::ws"],"exploits":{"exploitdb":1,"first_seen":"2005-09-22","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2005-09-22","kind":"exploitdb","ref":"1224","stars":null,"title":"Mozilla Browsers -
