Vulnerability Details:

CVE-ID: CVE-2013-7423

Description: GNU glibc could allow a local attacker to obtain sensitive information, caused by the writing of DNS queries to random file descriptors under high load by the getaddrinfo() function. An attacker could exploit this vulnerability to obtain sensitive information.

CVSS Base Score: 1.20
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/vulnerabilities/100647&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:H/Au:N/C:P/I:N/A:N)

CVE-ID: CVE-2014-7817

Description: GNU C Library (glibc) could allow a local attacker to execute arbitrary commands on the sys tem, caused by an error in the wordexp() function. An attacker could exploit this vulnerability to execute arbitrary commands on the system.

CVSS Base Score: 4.60
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/vulnerabilities/98852&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:L/Au:N/C:P/I:P/A:P)

CVE-ID: CVE-2014-9402

Description: glibc is vulnerable to a denial of service, caused by an error in the getanswer_r() function. If the DNS backend is activated, a remote attacker could exploit this vulnerability to cause the application to enter into an infinite loop.
