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-2026-115942/ (Markdown: https://insights.sbomify.com/CVE-2026-115942/index.md)","id":"CVE-2026-115942","markdown":"https://insights.sbomify.com/CVE-2026-115942/index.md","name":"CVE-2026-115942","record":{"aliases":["DEBIAN-CVE-2026-115942","GHSA-h5r3-v75j-gx8v"],"analysis":null,"analysis_generated_by":null,"assigner":"apache","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A misconfigured wildcard TLS certificate causes a stack read overflow.\n\nThis issue does not affect any wildcard certificate issued to the RFC9525 standard - the fix only accepts certificates that comply to this standard.\n\nThis issue affects Apache Qpid Proton C: through 0.40.0.\n\nUsers are recommended to upgrade to version 0.41.1, which fixes the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Apache Qpid Proton C: Verifying non compliant TLS wildcard cert can cause stack buffer overflow read","id":"CVE-2026-115942","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Spreadsheet::XLSX versions before 0.19 for Perl allow code execution via string eval of number format conditions in ExcelFmt.","id":"CVE-2026-115943"},"packages":[],"prev":{"headline":"Low privilege condition filter escapes Twig sandbox, recovers \"securityKey\" and reaches RCE","id":"CVE-2026-115938"},"products":["Apache Qpid Proton C"],"published":"2026-10-29","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-29","vendors":["Apache Software Foundation"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-115942/"}
