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&gt; 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

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

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.
