{"id":"UBUNTU-CVE-2024-3296","details":"A timing-based side-channel flaw exists in the rust-openssl package, which could be sufficient to recover a plaintext across a network in a Bleichenbacher-style attack. 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.","modified":"2026-05-20T16:17:15.185463547Z","published":"2024-04-04T14:15:00Z","upstream":["CVE-2024-3296"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-3296"},{"type":"REPORT","url":"https://github.com/sfackler/rust-openssl/issues/2171"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-3296"}],"affected":[{"package":{"name":"rust-openssl","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/rust-openssl?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.23-1","0.10.23-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.10.23-1ubuntu0.1~esm1","binary_name":"librust-openssl-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-3296.json"}},{"package":{"name":"rust-openssl","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/rust-openssl?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.29-1","0.10.36-1","0.10.36-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.10.36-1ubuntu0.1~esm1","binary_name":"librust-openssl-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-3296.json"}},{"package":{"name":"rust-openssl","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/rust-openssl?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.45-1","0.10.57-1","0.10.57-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.10.57-1ubuntu0.1~esm1","binary_name":"librust-openssl-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-3296.json"}},{"package":{"name":"rust-openssl","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/rust-openssl?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.70-1","0.10.72-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.10.72-1","binary_name":"librust-openssl-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-3296.json"}},{"package":{"name":"rust-openssl","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rust-openssl?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.72-1","0.10.73-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.10.73-1","binary_name":"librust-openssl-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-3296.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
