Description
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to the way glibc creates threads with pthread_create and then works with internal cache to find already mmaped regions. A local user can create a specially crafted application that can abuse this feature and bypass implemented ASLR protection.
Remediation
Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
