Keybase: Keybase client (Windows 10): Write files anywhere in userland using relative path in "download attachement" feature

Summary I've tested this vulnerability on Windows 10, with last keybase client. If a user click on "Download file" during a chat, an attacker can write files anywhere in userland. When downloading a file from a chat, the file should always be written in "Downloads" folder. Proof of concept You ne...

FreeBSD : FreeBSD -- Kernel memory disclosure in freebsd32_ioctl (6b856e00-b30a-11e9-a87f-a4badb2f4699)

Due to insufficient initialization of memory copied to userland in the components listed above small amounts of kernel memory may be disclosed to userland processes. Impact : A user who can invoke 32-bit FreeBSD ioctls may be able to read the contents of small portions of kernel memory. Such memo...

FreeBSD : FreeBSD -- Privilege escalation in cd(4) driver (14a3b376-b30a-11e9-a87f-a4badb2f4699)

To implement one particular ioctl, the Linux emulation code used a special interface present in the cd4 driver which allows it to copy subchannel information directly to a kernel address. This interface was erroneously made accessible to userland, allowing users with read access to a cd4 device t...
