kernel: fs_context: heap overflow in legacy parameter handling

A heap-based buffer overflow flaw was found in the way the legacyparseparam function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged in case of unprivileged user namespaces enabled, otherwise needs namespaced CAPSYSADMIN privile...

Code injection

Context relabeling of filesystems is vulnerable to symbolic link attack, allowing a local, unprivileged malicious entity to change the SELinux context of an arbitrary file to a context with few restrictions. This only happens when the relabeling process is done, usually when taking SELinux state...
