A security vulnerability in the Solaris Named Pipes (pipe(2)) may allow a local unprivileged user to gain access to unauthorized memory locations. This may allow a local unprivileged user to read potentially sensitive data in the kernel's memory layout or in the memory layouts of other processes running on the system.
