Vulnerability Details

CVEID:

CVE-2015-7547

DESCRIPTION:

GNU C Library (glibc) is vulnerable to a stack-based buffer overflow, caused
by improper bounds checking by the nss_dns backend for the getaddrinfo()
function when performing dual A/AAAA DNS queries. By sending a specially
crafted DNS response, a remote attacker could overflow a buffer and execute
arbitrary code on the system or cause the application to crash.

CVSS Base Score: 8.1
