Descriptions

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_core: Fix not checking skb length on hci_acldata_packet This fixes not checking if skb really contains an ACL header otherwise
the code may attempt to access some uninitilized/invalid memory past the
valid skb->data.

A use-after-free vulnerability was found in the Linux kernel. The Bluetooth firmware isn't checked if skb contains an ACL header, otherwise the code may attempt to access some uninitialized or invalid memory past the valid skb->data.

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_core: Fix not checking skb length on hci_acldata_packet This fixes not checking if skb really contains an ACL header otherwise the code may attempt to access some uninitilized/invalid memory past the valid skb->data.

Michael Randrianantenaina discovered that the Bluetooth driver in the Linux Kernel contained an improper access control vulnerability. A nearby attacker could use this to connect a rogue device and possibly execute arbitrary code. Attila Szász discovered that the HFS+ file system implementation in the Linux Kernel contained a heap overflow vulnerability. An attacker could use a specially crafted file system image that, when mounted, could cause a denial of service or possibly execute arbitrary code.
