OpenSSL / ntp / bind / boinc certificate validation cryptographic vulnerabilities
updated since 09.01.2009 | | Published: |  | 10.02.2009 | | Source: |  | BUGTRAQ | | SecurityVulns ID: |  | 9564 | | Type: |  | library | | Level: |  | 7/10 | | Description: |  | Multiple vulnerabilities in SSL/TLS DSA/ECDSA certificate chain validations. |
| Affected: |  | OPENSSL : OpenSSL 0.9 | | | | BIND : bind 9.3 | | | | BIND : bind 9.4 | | | | NTP : ntp 4.2 | | | | LASSO : lasso 2.2 | | | | BOINC : boinc 5.4 | | CVE: |  | CVE-2009-0126 (The decrypt_public function in lib/crypt.cpp in the client in Berkeley Open Infrastructure for Network Computing (BOINC) 6.2.14 and 6.4.5 does not check the return value from the OpenSSL RSA_public_decrypt function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077.) | | | | CVE-2009-0050 (Lasso 2.2.1 and earlier does not properly check the return value from the OpenSSL DSA_verify function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077.) | | | | CVE-2009-0025 (BIND 9.6.0, 9.5.1, 9.5.0, 9.4.3, and earlier does not properly check the return value from the OpenSSL DSA_verify function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077.) | | | | CVE-2009-0021 (NTP 4.2.4 before 4.2.4p5 and 4.2.5 before 4.2.5p150 does not properly check the return value from the OpenSSL EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys, a similar vulnerability to CVE-2008-5077.) | | | | CVE-2008-5077 (OpenSSL 0.9.8i and earlier does not properly check the return value from the EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys.) |
