Red Hat Security Advisory 2016-1617-01

Red Hat Security Advisory 2016-1617-01 – The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: A flaw was found in the way certain interfaces of the Linux kernel’s Infiniband subsystem used write() as bi-directional ioctl() replacement, which could lead to insufficient memory security checks when being invoked using the splice() system call. A local unprivileged user on a system with either Infiniband hardware present or RDMA Userspace Connection Manager Access module explicitly loaded, could use this flaw to escalate their privileges on the system.

Tor-ramdisk i686 UClibc-based Linux Distribution x86 20160810

Tor-ramdisk is an i686 uClibc-based micro Linux distribution whose only purpose is to host a Tor server in an environment that maximizes security and privacy. Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. Security is enhanced by employing a monolithically compiled GRSEC/PAX patched kernel and hardened system tools. Privacy is enhanced by turning off logging at all levels so that even the Tor operator only has access to minimal information. Finally, since everything runs in ephemeral memory, no information survives a reboot, except for the Tor configuration file and the private RSA key which may be exported/imported by FTP. x86_64 version.
