Description

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.

Remediation

Update to version 4.11.6.
