EUVDB-ID: #VU9992
Risk: Low
CVSSv3.1: 8.6 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:F/RL:U/RC:C]
CVE-ID: CVE-2018-1000001
CWE-ID:
CWE-124 - Buffer Underwrite ('Buffer Underflow')
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists in due to a change in the processing of pathnames in the getcwd() command introduced in Linux kernel. A local attacker can use a specially crafted application, trigger buffer underflow in the __realpath() function in 'stdlib/canonicalize.c' and execute arbitrary code with root privileges.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected package lib32-glibc to version 2.26-11.
