When MISP before 2.4.80 is configured with X.509 certificate authentication (CertAuth) in conjunction with a non-MISP external user management ReST API, if an external user provides X.509 certificate authentication and this API returns an empty value, the unauthenticated user can be granted access as an arbitrary user.

In Apple iOS 7 through 9, due to a BlueBorne flaw in the implementation of LEAP (Low Energy Audio Protocol), a large audio command can be sent to a targeted device and lead to a heap overflow with attacker-controlled data. Since the audio commands sent via LEAP are not properly validated, an attacker can use this overflow to gain full control of the device through the relatively high privileges of the Bluetooth stack in iOS. The attack bypasses Bluetooth access control; however, the default "Bluetooth On" value must be present in Settings.

A parameter verification issue was discovered in Xen through 4.9.x. The function `alloc_heap_pages` allows callers to specify the first NUMA node that should be used for allocations through the `memflags` parameter; the node is extracted using the `MEMF_get_node` macro. While the function checks to see if the special constant `NUMA_NO_NODE` is specified, it otherwise does not handle the case where `node >= MAX_NUMNODES`. This allows an out-of-bounds access to an internal array.

A domain cleanup issue was discovered in the C xenstore daemon (aka cxenstored) in Xen through 4.9.x. When shutting down a VM with a stubdomain, a race in cxenstored may cause a double-free. The xenstored daemon may crash, resulting in a DoS of any parts of the system relying on it (including domain creation / destruction, ballooning, device changes, etc.).

An issue was discovered in Xen 4.5.x through 4.9.x. The function `__gnttab_cache_flush` handles GNTTABOP_cache_flush grant table operations. It checks to see if the calling domain is the owner of the page that is to be operated on. If it is not, the owner's grant table is checked to see if a grant mapping to the calling domain exists for the page in question. However, the function does not check to see if the owning domain actually has a grant table or not. Some special domains, such as `DOMID_XEN`, `DOMID_IO` and `DOMID_COW` are created without grant tables. Hence, if __gnttab_cache_flush operates on a page owned by these special domains, it will attempt to dereference a NULL pointer in the domain struct.

A grant unmapping issue was discovered in Xen through 4.9.x. When removing or replacing a grant mapping, the x86 PV specific path needs to make sure page table entries remain in sync with other accounting done. Although the identity of the page frame was validated correctly, neither the presence of the mapping nor page writability were taken into account.
