Summary
GNU C library (glibc) vulnerability that has been referred to as GHOST affects Power Hardware Management Console.
Vulnerability Details
CVEID: CVE-2015-0235
DESCRIPTION:The gethostbyname functions of the GNU C Library (glibc) are vulnerable to a buffer overflow. By sending a specially crafted, but valid hostname argument, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the targeted process or cause the process to crash. The impact of an attack depends on the implementation details of the targeted application or operating system. This issue is being referred to as the "Ghost" vulnerability.
CVSS Base Score: 7.6
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/100386for the current score
