It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-20454 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2019-20454/ (Markdown: https://insights.sbomify.com/CVE-2019-20454/index.md)","id":"CVE-2019-20454","markdown":"https://insights.sbomify.com/CVE-2019-20454/index.md","name":"CVE-2019-20454","record":{"aliases":["ALSA-2020:4539","DEBIAN-CVE-2019-20454","GHSA-6wcm-vmc4-h93p","MGASA-2020-0305","RHSA-2020:4539","RLSA-2020:4539","UBUNTU-CVE-2019-20454"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PCRE library","requires_auth":"none","summary":"An out-of-bounds read in PCRE allows attackers to crash applications parsing untrusted input via crafted patterns.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"pcre2","vendor":"pcre"},{"product":"universal_forwarder","vendor":"splunk"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:3.0/AC:H/AV:L/A:H/C:N/I:N/PR:N/S:U/UI:N","version":"3.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"An out-of-bounds read was discovered in PCRE before 10.34 when the pattern \\X is JIT compiled and used to match specially crafted subjects in non-UTF mode.
