CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L)

CVEID: CVE-2017-15670
DESCRIPTION: GNU C Library is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the glob function in glob.c. By sending a specially-crafted string, a remote attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base Score: 7.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/133915 for the current score
CVSS Environmental Score*: Undefined
