Last modified

CVE-2013-5666 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.31% chance of exploitation in the next 30 days.
