{"id":"ALPINE-CVE-2026-34183","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":"2026-09-17T17:30:02.487009982Z","published":"2026-06-09T17:17:05Z","upstream":["CVE-2026-34183"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-34183"}],"affected":[{"package":{"name":"openssl","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.4.0"},{"fixed":"3.3.7-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-34183.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.4.0"},{"fixed":"3.5.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-34183.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.4.0"},{"fixed":"3.5.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-34183.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.4.0"},{"fixed":"3.5.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-34183.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
