Security Bulletin: IBM BladeCenter Advanced Management Module is affected by glibc vulnerabilities (CVE-2015-1472, CVE-2013-7423, CVE-2014-7817, and CVE-2014-9402)

Vulnerability Details

Summary

Security vulnerabilities in glibc affect IBM BladeCenter Advanced Management Module (AMM).

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: 1.2
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/100647 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 system, caused by an error in the wordexp() function. An attacker could exploit this vulnerability to execute arbitrary commands on the system.

CVSS Base Score: 4.6
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/98852 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() function. If the DNS backend is activated, a remote attacker could exploit this vulnerability to cause the application to enter into an infinite loop.

CVSS Base Score: 4.3
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/99289 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2015-1472

Description: NU glibc is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by stdio-common/vfscanf.c. By sending an overly long string, a local attacker could overflow a buffer and execute arbitrary code on the system or cause a denial of service.

CVSS Base Score: 4.6
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/100635 for current score
CVSS Environmental Score*: Undefined
