An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2019-11745 and fix it if it is affected.\n\nWhat it is: CVE-2019-11745 is a high-severity memory corruption vulnerability in Canonical Ubuntu Linux, published on 8 Jan 2020. 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-2019-11745 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-2019-11745/ (Markdown: https://insights.sbomify.com/CVE-2019-11745/index.md)","id":"CVE-2019-11745","markdown":"https://insights.sbomify.com/CVE-2019-11745/index.md","name":"CVE-2019-11745","record":{"aliases":["ALPINE-CVE-2019-11745","DEBIAN-CVE-2019-11745","DLA-2008-1","GHSA-gmvm-jpfj-v3f5","MGASA-2019-0374","RHSA-2019:4114","RHSA-2019:4152","RHSA-2020:0243","RHSA-2020:0466","UBUNTU-CVE-2019-11745","USN-4203-1","USN-4203-2"],"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":"An out-of-bounds write in block cipher encryption can cause heap corruption, potentially leading to code execution or crashes in Firefox and Thunderbird.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mozilla","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"firefox","vendor":"mozilla"},{"product":"firefox_esr","vendor":"mozilla"},{"product":"thunderbird","vendor":"mozilla"},{"product":"leap","vendor":"opensuse"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"ruggedcom_rox_mx5000_firmware","vendor":"siemens"},{"product":"ruggedcom_rox_rx1400_firmware","vendor":"siemens"},{"product":"ruggedcom_rox_rx1500_firmware","vendor":"siemens"},{"product":"ruggedcom_rox_rx1501_firmware","vendor":"siemens"},{"product":"ruggedcom_rox_rx1510_firmware","vendor":"siemens"},{"product":"ruggedcom_rox_rx1511_firmware","vendor":"siemens"},{"product":"ruggedcom_rox_rx1512_firmware","vendor":"siemens"},{"product":"ruggedcom_rox_rx5000_firmware","vendor":"siemens"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the block size, a small out of bounds write could occur.
