FreeBSD 9.2-RC1 and 9.2-RC2 - Kernel Memory Exposure via sendfile System Call

Title source: llm
STIX 2.1

Description

The sendfile system-call implementation in sys/kern/uipc_syscalls.c in the kernel in FreeBSD 9.2-RC1 and 9.2-RC2 does not properly pad transmissions, which allows local users to obtain sensitive information (kernel memory) via a length greater than the length of the file.
