Description

This security bulletin contains information about 2 vulnerabilities.


1) Security restrictions bypass (CVE-ID: CVE-2017-7482)

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

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


The vulnerability allows a local attacker to bypass security restrictions on the target system.

The weakness exists due to the failure to take the argument and environment strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the size) into account when imposing a size restriction. A local attacker can bypass security limitation and perform unauthorized actions.

Successful exploitation of the vulnerability results in access to the system.
