glibc: glibc: Incorrect DNS response parsing via crafted DNS server response

A flaw was found in glibc the GNU C Library. When an application uses the gethostbyaddr or gethostbyaddrr functions with a nsswitch.conf configuration that specifies glibc's DNS backend, a remote attacker can send a specially crafted DNS Domain Name System response. This crafted response can caus...
