Cisco TelePresence Video Communication Server GNU glibc gethostbyname Function Buffer Overflow Vulnerability (GHOST)

Critical Nessus Plugin ID 81408

Synopsis

The version of Cisco TelePresence Video Communication Server installed on the remote host is affected by a buffer overflow vulnerability.

Description

According to its self-reported version number, the Cisco TelePresence Video Communication Server is 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

Upgrade to version 8.2 / 8.5 or later.
