{"id":"UBUNTU-CVE-2024-25714","details":"In Rhonabwy through 1.1.13, HMAC signature verification uses a strcmp function that is vulnerable to side-channel attacks, because it stops the comparison when the first difference is spotted in the two signatures. (The fix uses gnutls_memcmp, which has constant-time execution.)","modified":"2026-04-22T14:41:54.072209Z","published":"2024-02-11T03:15:00Z","upstream":["CVE-2024-25714"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-25714"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-25714"}],"affected":[{"package":{"name":"rhonabwy","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/rhonabwy@1.1.2-1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.13-4","1.1.2-1"],"ecosystem_specific":{"binaries":[{"binary_name":"librhonabwy1.1","binary_version":"1.1.2-1"},{"binary_name":"rnbyc","binary_version":"1.1.2-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-25714.json"}},{"package":{"name":"rhonabwy","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rhonabwy@1.1.13-2.1build3?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.11-1","1.1.12-1","1.1.13-1","1.1.13-2","1.1.13-2.1build2","1.1.13-2.1build3"],"ecosystem_specific":{"binaries":[{"binary_name":"librhonabwy1.1t64","binary_version":"1.1.13-2.1build3"},{"binary_name":"rnbyc","binary_version":"1.1.13-2.1build3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-25714.json"}},{"package":{"name":"rhonabwy","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/rhonabwy@1.1.13-2.1build3?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.13-2.1build3"],"ecosystem_specific":{"binaries":[{"binary_name":"librhonabwy1.1t64","binary_version":"1.1.13-2.1build3"},{"binary_name":"rnbyc","binary_version":"1.1.13-2.1build3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-25714.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
