"category": "no_fix_planned", "details": "Deprioritize: exploiting CVE-2022-34903 requires an attacker to already possess secret‑key material from the target’s keyring and to target software that programmatically trusts GnuPG status‑line output (e.g., via GPGME); it does not break the underlying cryptography or provide code execution. These strict prerequisites are rarely met in managed server/VM workflows where OpenPGP secret keys are not exposed to untrusted parties and verification does not rely on printable status text alone, making practical exploitation unlikely. The flaw has also been corrected in longstanding GnuPG releases (2.3.7 and the 2.2.35+ updates), further limiting residual risk.", "product_ids": [ "CentOS-Stream-8:gnupg2-0:2.2.20-3.el8.tuxcare.els1.x86_64", "CentOS-Stream-8:gnupg2-0:2.2.20-3.el8.x86_64", "CentOS-Stream-8:gnupg2-smime-0:2.2.20-3.el8.tuxcare.els1.x86_64", "CentOS-Stream-8:gnupg2-smime-0:2.2.20-3.el8.x86_64" ] } ], "scores": [ { "cvss_v2": { "accessComplexity": "MEDIUM", "accessVector": "NETWORK", "authentication": "NONE", "availabilityImpact": "NONE", "baseScore": 5.8, "baseSeverity": "MEDIUM", "confidentialityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "vectorString": "AV:N/AC:M/Au:N/C:P/I:P/A:N", "version": "2.0" }, "cvss_v3": { "attackComplexity": "HIGH", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 6.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "HIGH", "integrityImpact": "LOW", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N", "version": "3.1" }, "products": [ "CentOS-Stream-8:gnupg2-0:2.2.20-3.el8.tuxcare.els1.x86_64", "CentOS-Stream-8:gnupg2-0:2.2.20-3.el8.x86_64", "CentOS-Stream-8:gnupg2-smime-0:2.2.20-3.el8.tuxcare.els1.x86_64", "CentOS-Stream-8:gnupg2-smime-0:2.2.20-3.el8.x86_64" ] } ], "threats": [ { "category": "impact", "details": "Moderate" } ] } ] }
