{"id":"JLSEC-2026-1136","summary":"Issue summary: Remote peer may exhaust heap memory of the QUIC server or client by flooding it...","details":"Issue summary: Remote peer may exhaust heap memory of the QUIC\nserver or client by flooding it with packets containing `PATH_CHALLENGE`\nframes.\n\nImpact summary: A malicious remote peer can cause an unbounded\nmemory allocation which can lead to an abnormal termination of the\napplication acting as a QUIC client or server and a Denial of Service.\n\nA remote peer may exhaust heap memory by flooding the local\nQUIC stack with `PATH_CHALLENGE` frames. The local QUIC stack\nallocates a `PATH_RESPONSE` frame for every `PATH_CHALLENGE` it receives.\nThe allocated `PATH_RESPONSE` frame gets freed only when the remote\npeer acknowledges reception of the `PATH_RESPONSE` frame which will\nnot be done by a malicious peer.\n\nThe FIPS modules in 4.0, 3.6, 3.5, 3.4, and 3.0 are not affected by\nthis issue. The QUIC stack is outside of OpenSSL FIPS module\nboundary.","modified":"2026-08-03T19:20:53.755640207Z","published":"2026-08-03T19:08:57.739Z","upstream":["CVE-2026-34183","EUVD-2026-35479","GHSA-f5vx-f6jp-89j6"],"database_specific":{"license":"CC-BY-4.0","sources":[{"published":"2026-06-09T17:17:05Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-34183","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34183","database_specific":{"status":"Analyzed"},"id":"CVE-2026-34183","imported":"2026-08-03T18:18:15.519Z","modified":"2026-07-23T08:10:00.137Z"},{"id":"GHSA-f5vx-f6jp-89j6","imported":"2026-08-03T18:19:52.623Z","modified":"2026-06-10T18:31:41Z","published":"2026-06-09T18:30:41Z","url":"https://api.github.com/advisories/GHSA-f5vx-f6jp-89j6","html_url":"https://github.com/advisories/GHSA-f5vx-f6jp-89j6"},{"imported":"2026-08-03T18:18:17.811Z","modified":"2026-06-10T15:51:12Z","published":"2026-06-09T16:03:23Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-35479","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-35479","id":"EUVD-2026-35479"}]},"references":[{"type":"WEB","url":"https://github.com/advisories/GHSA-f5vx-f6jp-89j6"},{"type":"WEB","url":"https://github.com/openssl/openssl/commit/5b306efb0b3779dfdd0803b4afc9d08c91f11517"},{"type":"WEB","url":"https://github.com/openssl/openssl/commit/7d06955ebe0ecf8adfd4c1e92018586da47ef9ac"},{"type":"WEB","url":"https://github.com/openssl/openssl/commit/d2e9efbe4900a373227deb136e8665401404ffac"},{"type":"WEB","url":"https://github.com/openssl/openssl/commit/fbaa83859c01ad64f497b757aaf51be7d05ed9eb"},{"type":"WEB","url":"https://github.com/openssl/security/commit/5b306efb0b3779dfdd0803b4afc9d08c91f11517"},{"type":"WEB","url":"https://github.com/openssl/security/commit/7d06955ebe0ecf8adfd4c1e92018586da47ef9ac"},{"type":"WEB","url":"https://github.com/openssl/security/commit/d2e9efbe4900a373227deb136e8665401404ffac"},{"type":"WEB","url":"https://github.com/openssl/security/commit/fbaa83859c01ad64f497b757aaf51be7d05ed9eb"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34183"},{"type":"WEB","url":"https://openssl-library.org/news/secadv/20260609.txt"}],"affected":[{"package":{"name":"AppBundler","ecosystem":"Julia","purl":"pkg:julia/AppBundler?uuid=40eb83ae-c93a-480c-8f39-f018b568f472"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.0.0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1136.json"}},{"package":{"name":"OpenSSL_jll","ecosystem":"Julia","purl":"pkg:julia/OpenSSL_jll?uuid=458c3c95-2e84-50aa-8efc-19380b2a3a95"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.5.0+0"},{"fixed":"3.5.7+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1136.json"}},{"package":{"name":"Openresty_jll","ecosystem":"Julia","purl":"pkg:julia/Openresty_jll?uuid=87da34d4-7b1b-5a94-8376-8cb65bf3132c"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.29.203+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1136.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
