The libCheckSignature function in crypto-utils.lib for OpenCA 0.9.1.6 and earlier only compares the serial of the signers certificate and the one in the database, which can cause OpenCA to incorrectly accept a signature if the certificates chain is trusted by OpenCAs chain directory, allowing remote attackers to spoof requests from other users.
