Description:
Sven Berkvens and Marc Olzheim have reported a vulnerability in FreeBSD, which can be exploited by malicious, local users to gain knowledge of sensitive information.
The vulnerability is caused due to an error in the "sendfile()" system call and can be exploited by transmitting a large file and then truncate it before the transfer is complete.
Successful exploitation discloses random portions of kernel memory.
