FreeBSD : FreeBSD -- libfetch out of bounds read (d22b336d-0567-11ec-b69d-4062311215d5)

The passive mode in FTP communication allows an out of boundary read while libfetch uses strtol to parse the relevant numbers into address bytes. It does not check if the line ends prematurely. If it does, the for-loop condition checks for p == '\0' one byte too late because p++ was already...

How to install custom FreeBSD configuration files on a Netscaler

FreeBSD : FreeBSD -- Remote code execution in ggatec(8) (3e9d2fde-0567-11ec-b69d-4062311215d5)

The ggatec8 daemon does not validate the size of a response before writing it to a fixed-sized buffer. This allows to overwrite the stack of ggatec8. Impact : A malicious ggated8 or an attacker in a priviledged network position can overwrite the stack with crafted content and potentially execute...

FreeBSD : FreeBSD -- Missing error handling in bhyve(8) device models (a6d5d4c1-0564-11ec-b69d-4062311215d5)

Certain VirtIO-based device models failed to handle errors when fetching I/O descriptors. Such errors could be triggered by a malicious guest. As a result, the device model code could be tricked into operating on uninitialized I/O vectors, leading to memory corruption. Impact : A malicious guest...
