Description

This security bulletin contains information about 3 vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2018-1124)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 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


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.

2) Privilege escalation (CVE-ID: CVE-2018-11260)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to flaws in the Qualcomm component. A remote attacker can bypass user interaction requirements and gain elevated privileges.


3) Buffer overflow (CVE-ID: CVE-2018-1126)

CWE-ID: CWE-120 - Buffer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to improper bounds checking. A remote attacker can send a specially crafted request, trigger memory corruption and execute arbitrary code with elevated privileges.
