Discussion

grsecurity Multiple RBAC Local Security Bypass Vulnerabilities

The 'grsecurity' application is prone to multiple local security-bypass vulnerabilities because it fails to properly handle return values to certain functions in the RBAC (Role-Based Access Control) system.

Successful exploits will allow attackers to bypass certain security restrictions.

Versions prior to grsecurity 2.1.11-2.6.24.5 (2008-04-21) and 2.1.11-2.4.36.2 (2008-04-21) are affected.
