TITLE

Kerio Personal Firewall vulnerable to buffer overflow

Trust: 0.8

sources: CERT/CC: VU#454716

DESCRIPTION

Buffer overflow in the administrator authentication process for Kerio Personal Firewall (KPF) 2.1.4 and earlier allows remote attackers to execute arbitrary code via a handshake packet. An exploit for this vulnerability is publicly available. A buffer-overflow vulnerability has been discovered in Kerio Personal Firewall. The problem occurs during the administration authentication process. An attacker could exploit this vulnerability by forging a malicious packet containing an excessive data size. The application then reads this data into a static memory buffer without first performing sufficient bounds checking. Note that this vulnerability affects Kerio Personal Firewall 2.1.4 and earlier. When the administrator connects to the firewall, a handshake connection will be performed to establish an encrypted session. The fourth packet of the handshake (the first packet is sent by the administrator) contains 4 bytes of data, which has a certain fixed value 0x40 (64) to indicate the follow-up The size of the package containing the admin key. When the firewall side uses recv() to process this data, it does not check the boundary buffer
