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.\n\n## Affected\n\n- `perl-Crypt-OpenSSL-RSA (all versions)`\n- `perl-Crypt-OpenSSL-RSA`\n- `perl-Crypt-OpenSSL-RSA`\n- `perl-Crypt-OpenSSL-RSA (all versions)`\n- `perl-Crypt-OpenSSL-RSA (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nThis CVE is mitigated (i.e. not exploitable) by using the openssl package with support for implicit rejection shipped in the following RHEL errata:\n\n* https://access.redhat.com/errata/RHSA-2024:0208\n* https://access.redhat.com/errata/RHSA-2024:0154\n* https://access.redhat.com/errata/RHSA-2023:7877\n* https://access.redhat.com/errata/RHSA-2024:0500\n* https://access.redhat.com/errata/RHBA-2023:6627","depth":"sunlit","depthScore":33,"depthScoreParts":{"impact":32.5,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
