Kerio Connect 8.0.0 through 9.2.2, and Kerio Connect Client desktop application for Windows and Mac 9.2.0 through 9.2.2, when e-mail preview is enabled, allows remote attackers to conduct clickjacking attacks via a crafted e-mail message.

Cross-site scripting (XSS) vulnerability in the Integration page in the WebMail component in Kerio MailServer 6.6.0, 6.6.1, 6.6.2, and 6.7.0 allows remote attackers to inject arbitrary web script or HTML via an e-mail message.

Kerio MailServer 5.0 allows remote attackers to cause a denial of service (hang) via SYN packets to the supported network services.

Multiple cross-site scripting (XSS) vulnerabilities in the Web mail module of Kerio MailServer 5.0 allow remote attackers to execute HTML script as other users via certain URLs.

Unspecified vulnerability in Kerio MailServer before 6.0.3 has unknown impact and unknown remote attack vectors, related to a "potential security issue."

Kerio WinRoute Firewall before 6.0.9 uses information from PTR queries in response to A queries, which allows remote attackers to poison the DNS cache or cause a denial of service (connection loss).

Kerio Personal Firewall (KPF) 2.1.5 allows local users to execute arbitrary code with SYSTEM privileges via the Load button in the Firewall Configuration Files option, which does not drop privileges before opening the file loading dialog box.

The Web Filtering functionality in Kerio Personal Firewall (KPF) 4.0.13 allows remote attackers to cause a denial of service (crash) by sending hex-encoded URLs containing "%13%12%13".

Kerio Personal Firewall 4.0 (KPF4) allows local users with administrative privileges to bypass the Application Security feature and execute arbitrary processes by directly writing to \device\physicalmemory to restore the running kernel's SDT ServiceTable.

Kerio Winroute Firewall before 6.0.9, ServerFirewall before 1.0.1, and MailServer before 6.0.5, when installed on Windows based systems, do not modify the ACLs for critical files, which allows local users with Power Users privileges to modify programs, install malicious DLLs in the plug-ins folder, and modify XML files related to configuration.

The FWDRV.SYS driver in Kerio Personal Firewall 4.1.1 and earlier allows remote attackers to cause a denial of service (CPU consumption and system freeze from infinite loop) via a (1) TCP, (2) UDP, or (3) ICMP packet with a zero length IP Option field.

Kerio Winroute Firewall before 6.0.7, ServerFirewall before 1.0.1, and MailServer before 6.0.5 use symmetric encryption for user passwords, which allows attackers to decrypt the user database and obtain the passwords by extracting the secret key from within the software.

Unspecified vulnerability in Kerio WinRoute Firewall before 6.1.3 allows remote attackers to cause a denial of service (crash) via certain RTSP streams.
