Sun Solaris kernel security bypass

solaris-kernel-security-bypass (44753) The risk level is classified as MediumMedium Risk

Description:

Sun Solaris kernel could allow a local attacker to bypass security restrictions, caused by an error in the system calls. A local attacker could exploit this vulnerability to bypass multi-level security policy in Solaris Trusted Extensions or the zone or chroot isolation policy and establish a secret communication channel between two local processes.
