CVE-2009-0025: Medium severity ISC BIND vulnerability

Published Jan 7, 2009

Updated

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 DSAverify 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.
