Описание:Многочисленные проблемы с проверкой сертификатов DSA/ECDSA в SSL/TLS.
Затронутые продукты: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.)
