The Storage and Access service in BlackBerry OS 10.x before 10.2.1.1925 on Q5, Q10, Z10, and Z30 devices does not enforce the password requirement for SMB filesystem access, which allows context-dependent attackers to read arbitrary files via (1) a session over a Wi-Fi network or (2) a session over a USB connection in Development Mode.

Stack-based buffer overflow in a certain decryption function in qconnDoor on BlackBerry Z10 devices with software 10.1.0.2312, when developer-mode has been previously enabled, allows remote attackers to execute arbitrary code via a crafted packet in a TCP session on a wireless network.

BlackBerry 10 OS before 10.0.10.648 on BlackBerry Z10 smartphones uses weak permissions for a BlackBerry Protect object, which allows physically proximate attackers to bypass intended access restrictions by leveraging a user's BlackBerry Protect password-reset request and a user's installation of a crafted application.
