The amd64_set_ldt() function in sys/amd64/amd64/sys_machdep.c in the FreeBSD kernel code is prone to an integer signedness error when processing a system call with specially crafted parameters originated from user space. This issue ultimately leads to a kernel heap overflow, which can be used by unprivileged local attackers to cause a kernel panic and crash the machine.
VMware vCenter Server is prone to a remote vulnerability that allows attackers to take advantage of an insecure deployment of the JMX/RMI service used to manage and monitor the Java Virtual Machine. By exploiting known methods, it is possible to remotely load an MLet file from an attacker controlled web server that points at a jar file.
