{"id":"ALPINE-CVE-2026-28389","details":"Issue summary: During processing of a crafted CMS EnvelopedData message\nwith KeyAgreeRecipientInfo a NULL pointer dereference can happen.\n\nImpact summary: Applications that process attacker-controlled CMS data may\ncrash before authentication or cryptographic operations occur resulting in\nDenial of Service.\n\nWhen a CMS EnvelopedData message that uses KeyAgreeRecipientInfo is\nprocessed, the optional parameters field of KeyEncryptionAlgorithmIdentifier\nis examined without checking for its presence. This results in a NULL\npointer dereference if the field is missing.\n\nApplications and services that call CMS_decrypt() on untrusted input\n(e.g., S/MIME processing or CMS-based protocols) are vulnerable.\n\nThe FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this\nissue, as the affected code is outside the OpenSSL FIPS module boundary.","modified":"2026-04-11T08:31:30.016403Z","published":"2026-04-07T22:16:21.030Z","upstream":["CVE-2026-28389"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-28389"}],"affected":[{"package":{"name":"openssl","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.7-r0"}]}],"versions":["1.1.1-r0","1.1.1-r1","1.1.1-r2","1.1.1-r3","1.1.1-r4","1.1.1-r5","1.1.1a-r0","1.1.1a-r1","1.1.1b-r0","1.1.1b-r1","1.1.1c-r0","1.1.1c-r1","1.1.1d-r1","1.1.1d-r2","1.1.1d-r3","1.1.1d-r4","1.1.1d-r5","1.1.1e-r0","1.1.1f-r0","1.1.1g-r0","1.1.1h-r0","1.1.1i-r0","1.1.1j-r0","1.1.1k-r0","1.1.1k-r1","1.1.1l-r0","3.0.0-r0","3.0.0-r1","3.0.0-r2","3.0.0-r3","3.0.0-r4","3.0.1-r0","3.0.1-r1","3.0.2-r0","3.0.3-r0","3.0.5-r0","3.0.5-r1","3.0.5-r2","3.0.5-r3","3.0.6-r0","3.0.7-r0","3.0.7-r1","3.0.7-r2","3.0.8-r0","3.0.8-r1","3.1.0-r0","3.1.0-r1","3.1.0-r2","3.1.0-r3","3.1.0-r4","3.1.0-r5","3.1.1-r0","3.1.1-r1","3.1.1-r2","3.1.1-r3","3.1.2-r0","3.1.3-r0","3.1.4-r0","3.1.4-r1","3.1.4-r2","3.1.4-r3","3.1.4-r4","3.1.4-r5","3.1.5-r5","3.2.1-r0","3.2.1-r1","3.2.1-r2","3.3.0-r0","3.3.0-r1","3.3.0-r2","3.3.0-r3","3.3.1-r0","3.3.1-r1","3.3.1-r2","3.3.1-r3","3.3.2-r0","3.3.2-r1","3.3.2-r2","3.3.3-r0","3.3.4-r0","3.3.5-r0","3.3.6-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-28389.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.7-r0"}]}],"versions":["1.1.1-r0","1.1.1-r1","1.1.1-r2","1.1.1-r3","1.1.1-r4","1.1.1-r5","1.1.1a-r0","1.1.1a-r1","1.1.1b-r0","1.1.1b-r1","1.1.1c-r0","1.1.1c-r1","1.1.1d-r1","1.1.1d-r2","1.1.1d-r3","1.1.1d-r4","1.1.1d-r5","1.1.1e-r0","1.1.1f-r0","1.1.1g-r0","1.1.1h-r0","1.1.1i-r0","1.1.1j-r0","1.1.1k-r0","1.1.1k-r1","1.1.1l-r0","3.0.0-r0","3.0.0-r1","3.0.0-r2","3.0.0-r3","3.0.0-r4","3.0.1-r0","3.0.1-r1","3.0.2-r0","3.0.3-r0","3.0.5-r0","3.0.5-r1","3.0.5-r2","3.0.5-r3","3.0.6-r0","3.0.7-r0","3.0.7-r1","3.0.7-r2","3.0.8-r0","3.0.8-r1","3.1.0-r0","3.1.0-r1","3.1.0-r2","3.1.0-r3","3.1.0-r4","3.1.0-r5","3.1.1-r0","3.1.1-r1","3.1.1-r2","3.1.1-r3","3.1.2-r0","3.1.3-r0","3.1.4-r0","3.1.4-r1","3.1.4-r2","3.1.4-r3","3.1.4-r4","3.1.4-r5","3.1.5-r5","3.2.1-r0","3.2.1-r1","3.2.1-r2","3.3.0-r0","3.3.0-r1","3.3.0-r2","3.3.0-r3","3.3.1-r0","3.3.1-r1","3.3.1-r2","3.3.1-r3","3.3.2-r0","3.3.2-r1","3.3.2-r2","3.3.2-r3","3.3.2-r4","3.3.2-r5","3.3.2-r6","3.3.3-r0","3.3.4-r0","3.3.5-r0","3.3.6-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-28389.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.6-r0"}]}],"versions":["1.1.1-r0","1.1.1-r1","1.1.1-r2","1.1.1-r3","1.1.1-r4","1.1.1-r5","1.1.1a-r0","1.1.1a-r1","1.1.1b-r0","1.1.1b-r1","1.1.1c-r0","1.1.1c-r1","1.1.1d-r1","1.1.1d-r2","1.1.1d-r3","1.1.1d-r4","1.1.1d-r5","1.1.1e-r0","1.1.1f-r0","1.1.1g-r0","1.1.1h-r0","1.1.1i-r0","1.1.1j-r0","1.1.1k-r0","1.1.1k-r1","1.1.1l-r0","3.0.0-r0","3.0.0-r1","3.0.0-r2","3.0.0-r3","3.0.0-r4","3.0.1-r0","3.0.1-r1","3.0.2-r0","3.0.3-r0","3.0.5-r0","3.0.5-r1","3.0.5-r2","3.0.5-r3","3.0.6-r0","3.0.7-r0","3.0.7-r1","3.0.7-r2","3.0.8-r0","3.0.8-r1","3.1.0-r0","3.1.0-r1","3.1.0-r2","3.1.0-r3","3.1.0-r4","3.1.0-r5","3.1.1-r0","3.1.1-r1","3.1.1-r2","3.1.1-r3","3.1.2-r0","3.1.3-r0","3.1.4-r0","3.1.4-r1","3.1.4-r2","3.1.4-r3","3.1.4-r4","3.1.4-r5","3.1.5-r5","3.2.1-r0","3.2.1-r1","3.2.1-r2","3.3.0-r0","3.3.0-r1","3.3.0-r2","3.3.0-r3","3.3.1-r0","3.3.1-r1","3.3.1-r2","3.3.1-r3","3.3.2-r0","3.3.2-r1","3.3.2-r2","3.3.2-r3","3.3.2-r4","3.3.2-r5","3.3.2-r6","3.3.3-r0","3.5.0-r0","3.5.1-r0","3.5.2-r0","3.5.3-r0","3.5.3-r1","3.5.4-r0","3.5.5-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-28389.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.6-r0"}]}],"versions":["1.1.1-r0","1.1.1-r1","1.1.1-r2","1.1.1-r3","1.1.1-r4","1.1.1-r5","1.1.1a-r0","1.1.1a-r1","1.1.1b-r0","1.1.1b-r1","1.1.1c-r0","1.1.1c-r1","1.1.1d-r1","1.1.1d-r2","1.1.1d-r3","1.1.1d-r4","1.1.1d-r5","1.1.1e-r0","1.1.1f-r0","1.1.1g-r0","1.1.1h-r0","1.1.1i-r0","1.1.1j-r0","1.1.1k-r0","1.1.1k-r1","1.1.1l-r0","3.0.0-r0","3.0.0-r1","3.0.0-r2","3.0.0-r3","3.0.0-r4","3.0.1-r0","3.0.1-r1","3.0.2-r0","3.0.3-r0","3.0.5-r0","3.0.5-r1","3.0.5-r2","3.0.5-r3","3.0.6-r0","3.0.7-r0","3.0.7-r1","3.0.7-r2","3.0.8-r0","3.0.8-r1","3.1.0-r0","3.1.0-r1","3.1.0-r2","3.1.0-r3","3.1.0-r4","3.1.0-r5","3.1.1-r0","3.1.1-r1","3.1.1-r2","3.1.1-r3","3.1.2-r
