NSS code used for checking PKCS#1 v1.5 was leaking information useful in mounting Bleichenbacher-like attacks.\nBoth the overall correctness of the padding as well as the length of the encrypted message was leaking through timing side-channel.\nBy sending large number of attacker-selected ciphertexts, the attacker would be able to decrypt a previously intercepted PKCS#1 v1.5 ciphertext (for example, to decrypt a TLS session that used RSA key exchange), or forge a signature using the victim's key.\nThe issue was fixed by implementing the implicit rejection algorithm, in which the NSS returns a deterministic random message in case invalid padding is detected, as proposed in the Marvin Attack paper.","references":[{"reference_url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2023-4421.json","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}],"url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2023-4421.json"},{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2023-4421","reference_id":"","reference_type":"","scores":[{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.44959","published_at":"2026-05-07T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.44997","published_at":"2026-04-29T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.44892","published_at":"2026-05-05T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.45132","published_at":"2026-04-02T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.45154","published_at":"2026-04-04T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.45096","published_at":"2026-04-07T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.45149","published_at":"2026-04-09T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.45171","published_at":"2026-04-11T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.45138","published_at":"2026-04-12T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.4514","published_at":"2026-04-13T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.4519","published_at":"2026-04-16T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.45184","published_at":"2026-04-18T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.45135","published_at":"2026-04-21T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.45049","published_at":"2026-04-24T12:55:00Z"},{"value":"0.00224","scoring_system":"epss","scoring_elements":"0.45056","published_at":"2026-04-26T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2023-4421"},{"reference_url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-4421","reference_id":"","reference_type":"","scores":[],"url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-4421"},{"reference_url":"https://ftp.suse.com/pub/projects/security/yaml/suse-cvss-scores.yaml","reference_id":"","reference_type":"","scores":[{"value":"5.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}],"url":"https://ftp.suse.com/pub/projects/security/yaml/suse-cvss-scores.yaml"},{"reference_url":"https://bugzilla.redhat.com/show_bug.cgi?id=2238677","reference_id":"2238677","reference_type":"","scores":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2238677"},{"reference_url":"https://www.mozilla.org/en-US/security/advisories/mfsa2023-53","reference_id":"mfsa2023-53","reference_type":"","scores":[{"value":"none","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://www.mozilla.org/en-US/security/advisories/mfsa2023-53"},{"reference_url":"https://usn.ubuntu.com/6727-1/","reference_id":"USN-6727-1","reference_type":"","scores":[],"url":"https://usn.ubuntu.com/6727-1/"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/933001?format=json","purl":"pkg:deb/debian/nss@2:3.61-1?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/nss@2:3.61-1%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/932959?format=json","purl":"pkg:deb/debian/nss@2:3.61-1%2Bdeb11u3?distro=trixie","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-2tts-gwgd-zqcz"},{"vulnerability":"VCID-3nrj-5r53-37ab"},{"vulnerability":"VCID-7jt2-zr49-7ye5"},{"vulnerability":"VCID-fxjm-ywug-f3d5"},{"vulnerability":"VCID-hk2m-rbdy-nqhc"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/nss@2:3.61-1%252Bdeb11u3%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/932957?format=json","purl":"pkg:deb/debian/nss@2:3.87.1-1%2Bdeb12u1?distro=trixie","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-2tts-gwgd-zqcz"},{"vulnerability":"VCID-3nrj-5r53-37ab"},{"vulnerability":"VCID-7jt2-zr49-7ye5"},{"vulnerability":"VCID-fxjm-ywug-f3d5"},{"vulnerability":"VCID-gret-hn3p-5kbk"},{"vulnerability":"VCID-hk2m-rbdy-nqhc"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/nss@2:3.87.1-1%252Bdeb12u1%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/932961?format=json","purl":"pkg:deb/debian/nss@2:3.110-1%2Bdeb13u1?distro=trixie","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-7jt2-zr49-7ye5"},{"vulnerability":"VCID-fxjm-ywug-f3d5"},{"vulnerability":"VCID-hk2
