Hello, A critical vulnerability has been found in glibc [1] in the form of a heap buffer overflow in the gethostbyname() and gethostbyname2() calls. It may allow a remote attacker to execute arbitrary code. Arch Linux does not seem vulnerable because we use a recent glibc version, which includes a patch [2] for this issue. This seems confirmed by the test case included with the fix [3].
