CVE Details
| Release Date: | 2009-01-07 | |
| Impact: | Important | What is this? |
Description
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. 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. Evolution 2.22.3.1 checks S/MIME signatures against a copy of the e-mail text within a signed-data blob, not the copy of the e-mail text displayed to the user, which allows remote attackers to spoof a signature by modifying the latter copy, a different vulnerability than CVE-2008-5077. 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.
