Description:
A security issue has been reported in FreeBSD, which potentially can be exploited by malicious, local users to disclose sensitive information.
The problem is that the "sendfile" system call does not check the file descriptor access flags before sending data from a file. This can be exploited to e.g. open a write-only file and send the data even if a user has no read access.
Successful exploitation requires that the target file is write-only.
