The Cisco Application Control Engine (ACE) software installed on the remote Cisco IOS device is version A2(3.6d) or A5(3.1b). It is, therefore, affected by a heap-based buffer overflow vulnerability in the GNU C Library (glibc) due to improperly validating user-supplied input to the __nss_hostname_digits_dots(), gethostbyname(), and gethostbyname2() functions. This allows a remote attacker to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.
