BID: 93793
This tool allows you to overwrite an arbitrary file on Linux systems.
A race condition exists in the way the Linux kernel’s memory subsystem handles the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus gain elevated privileges on the system.
Upgrade to a fixed kernel package from your Linux vendor.
