Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Integer overflow
EUVDB-ID: #VU12977
Risk: Low
CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2018-1124
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: Yes
DescriptionThe 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.
