Vulnerability Details

CVEID: CVE-2017-15804 DESCRIPTION: GNU C Library (aka glibc or libc6) is vulnerable to a buffer overflow, caused by improper bounds checking by glob function in glob.c. By using a specially-crafted file, a local attacker could overflow a buffer.
CVSS Base Score: 5.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/133996&gt; for the current score
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-2017-15671 DESCRIPTION: GNU C Library is vulnerable to a denial of service, caused by a memory leak in the glob function in glob.c. A remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base Score: 7.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/133909&gt; for the current score
