Description:
eEye has discovered a vulnerability in ZoneAlarm and Integrity client, allowing users to escalate their privileges and potentially also allowing malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the SMTP processing system when handling outgoing email messages. This can be exploited to cause a buffer overflow by sending an email with an overly long value in a "RCPT TO:" header.
Successful exploitation allows execution of arbitrary code with SYSTEM privileges and can be remotely exploited without any user action if the SMTP service is running on a protected system.
The vulnerability has been reported to affect version 4.x. Prior versions are not vulnerable.
NOTE: According to the vendor, only a small percentage of users are affected, since this is an untypical setup as servers shouldn't be protected with the client security products.
