Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Integer overflow

EUVDB-ID: #VU12977

Risk: Low

CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2018-1124

CWE-ID: CWE-190 - Integer overflow

Exploit availability: Yes

Description

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to integer overflow in libprocps's file2strvec() function. A local attacker can execute a vulnerable utility (pgrep, pidof, pkill, and w are vulnerable by default; other utilities are vulnerable if executed with non-default options) and gain elevated privileges.

Mitigation

Install updates from vendor's website.
