To achieve successful decryption, an attacker would have to be able to send a large number of trial messages for decryption. The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding mode.","epss":{"date":"2026-11-04","percentile":0.35969,"score":0.00415},"exploits":[],"kev":null,"metrics":[{"score":5.9,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"}],"modifiedAt":1793881083706,"publishedAt":1712238444183,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2024-3296"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2269723"},{"source":"ADP: CVE","tags":["vdb-entry","x_refsource_REDHAT","x_transferred"],"url":"https://access.redhat.com/security/cve/CVE-2024-3296"},{"source":"ADP: CVE","tags":["issue-tracking","x_refsource_REDHAT","x_transferred"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2269723"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability."}],"revision":"570d554fa54e2c619c254db0f02390c45f05ca6b26547d2448d4d63ac26f7396","sources":[{"modifiedAt":1793881083706,"name":"CNA: redhat","retrievedAt":1793884117668,"url":"https://www.cve.org/CVERecord?id=CVE-2024-3296"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793884203133,"url":"https://api.first.org/data/v1/epss?cve=CVE-2024-3296"}],"ssvc":{"assessedAt":1712244488090,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Rust-openssl: timing based side-channel can lead to a bleichenbacher style attack","updatedAt":1793884203133}
