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

critical Nessus Plugin ID 81423

Language:

Synopsis

The remote device is affected by a buffer overflow vulnerability.

Description

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.

Solution

The vendor has stated that no release is planned to fix this issue.
Contact the vendor for other possible options.
