Cisco Application Control Engine GNU glibc gethostbyname Function Buffer Overflow Vulnerability (cisco-sa-20150128-ghost) (GHOST)

critical Nessus Plugin ID 81423


The remote device is affected by a buffer overflow vulnerability.


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.


The vendor has stated that no release is planned to fix this issue.
