{"id":"UBUNTU-CVE-2024-2467","details":"A timing-based side-channel flaw exists in the perl-Crypt-OpenSSL-RSA package, which could be sufficient to recover 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. The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding mode.","modified":"2026-01-20T18:37:05.918393Z","published":"2024-04-25T17:15:00Z","upstream":["CVE-2024-2467"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-2467"},{"type":"REPORT","url":"https://people.redhat.com/~hkario/marvin/"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-2467"}],"affected":[{"package":{"name":"libcrypt-openssl-rsa-perl","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/libcrypt-openssl-rsa-perl@0.28-1build1?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.28-1","0.28-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libcrypt-openssl-rsa-perl","binary_version":"0.28-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-2467.json"}},{"package":{"name":"libcrypt-openssl-rsa-perl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libcrypt-openssl-rsa-perl@0.28-2build2?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.28-2build1","0.28-2build2"],"ecosystem_specific":{"binaries":[{"binary_name":"libcrypt-openssl-rsa-perl","binary_version":"0.28-2build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-2467.json"}},{"package":{"name":"libcrypt-openssl-rsa-perl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libcrypt-openssl-rsa-perl@0.28-5build2?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.28-5build1","0.28-5build2"],"ecosystem_specific":{"binaries":[{"binary_name":"libcrypt-openssl-rsa-perl","binary_version":"0.28-5build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-2467.json"}},{"package":{"name":"libcrypt-openssl-rsa-perl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libcrypt-openssl-rsa-perl@0.31-1build1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.31-1","0.31-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libcrypt-openssl-rsa-perl","binary_version":"0.31-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-2467.json"}},{"package":{"name":"libcrypt-openssl-rsa-perl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libcrypt-openssl-rsa-perl@0.32-1ubuntu2?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.31-1build3","0.32-1","0.32-1ubuntu1","0.32-1ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_name":"libcrypt-openssl-rsa-perl","binary_version":"0.32-1ubuntu2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-2467.json"}},{"package":{"name":"libcrypt-openssl-rsa-perl","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libcrypt-openssl-rsa-perl@0.33-3build4?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.33-3","0.33-3build1","0.33-3build3","0.33-3build4"],"ecosystem_specific":{"binaries":[{"binary_name":"libcrypt-openssl-rsa-perl","binary_version":"0.33-3build4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-2467.json"}},{"package":{"name":"libcrypt-openssl-rsa-perl","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/libcrypt-openssl-rsa-perl@0.35-1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.33-3build5","0.35-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libcrypt-openssl-rsa-perl","binary_version":"0.35-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-2467.json"}}],"schema_version":"1.7.3","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"}]}
