Cisco Unified Communications Manager IM and Presence GNU C Library (glibc) Buffer Overflow (CSCus69785) (GHOST)

Critical Nessus Plugin ID 85449

Synopsis

The remote host is missing a vendor-supplied security patch.

Description

According to its self-reported version, the Cisco Unified Communications Manager IM and Presence Server Service is affected by a heap-based buffer overflow condition in the GNU C Library (glibc) due to improper validation of user-supplied input to the glibc functions
__nss_hostname_digits_dots(), gethostbyname(), and gethostbyname2().
This allows a remote attacker to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.

Solution

Apply the relevant patch referenced in the Cisco bug ID CSCus69785.
