Security Bulletin: IBM BladeCenter Advanced Management Module (AMM) is affected by vulnerabilities in GNU C Library

Vulnerability Details

CVEID: CVE-2018-6551
DESCRIPTION: GNU glibc could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow in the malloc implementation. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base Score: 7.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/138610 for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2018-6485
DESCRIPTION: GNU C Library is vulnerable to a denial of service, caused by an integer overflow in the implementation of the posix_memalign in memalign functions. A local attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 4

CVEID: CVE-2018-1000001
DESCRIPTION: Glibc could allow a local attacker to execute arbitrary code on the system, caused by a buffer underflow in the __realpath() function in stdlib/canonicalize.c. An attacker could exploit this vulnerability to execute arbitrary code on the system and obtain privileges.
CVSS Base Score: 8.4

CVEID: CVE-2017-8804
DESCRIPTION: glibc is vulnerable to a denial of service, caused by improper handling of buffer deserialization in the xdr_bytes and xdr_string functions. By sending a specially-crafted UDP packet, a remote attacker could exploit this vulnerability to cause virtual memory allocation, or memory consumption on the system.
