Description:
A vulnerability has been reported in Sun Solaris, which can be exploited by malicious, local users to bypass certain security restrictions.
The vulnerability is caused due to an error within the Solaris kernel related to system calls. This can be exploited to establish a covert communication channel between two unprivileged processes, thus bypassing e.g. the multi-level security policy in Solaris Trusted Extensions or the isolation policy of zones(5) or chroot(2).
The vulnerability is reported in Solaris 8, 9, 10 for both the SPARC and x86 platforms.
