Summary
IBM Security Proventia Network Active Bypass has addressed the following vulnerabilities. (CVE-2018-1000001, CVE-2017-16997, CVE-2017-1000408, CVE-2017-1000409, CVE-2017-17426)
Vulnerability Details
CVEID: CVE-2017-17426
DESCRIPTION: GNU C Library (aka glibc or libc6) is vulnerable to a heap-based buffer overflow, caused by an integer overflow in the per-thread cache (aka tcache) feature. By allocating an object whose size is close to SIZE_MAX, a remote attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base Score: 9.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/135985 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2017-1000409
DESCRIPTION: glibc ld.so is vulnerable to a buffer overflow, caused by improper bounds checking by the _dl_init_paths() in the ld.so. A local attacker could overflow a buffer and cause the application to crash.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/136319 for the current score

CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2017-1000408
DESCRIPTION: glibc is vulnerable to a denial of service, caused by a memory leak in the ld.so. A local attacker could exploit this vulnerability to cause the system to crash.
CVSS Base Score: 4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/136318 for the current score

CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2017-16997
DESCRIPTION: GNU C Library could allow a local attacker to gain elevated privileges on the system, caused by a flaw in the elf/dl-load.c. By using a Trojan horse library, an attacker could exploit this vulnerability to gain elevated privileges on the system.
CVSS Base Score: 8.4

CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
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.
