Envcheck is a Linux kernel module which detects and prevents exploitation of the recent glibc vulnerabilities by intercepting the execve system call and sanitising the enviroment passed. At the cost of a very small performance penalty, it has advantages over a glibc upgrade, including logging of exploit attempts, it works with statically linked binaries, it is transparent to applications that may be sensitive to a change of glibc, and it partially protects libc5.
