In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Mobile and Snapdragon Wear MSM8909W, SD 210/SD 212/SD 205, SD 400, SD 410/12, SD 615/16/SD 415, SD 617, SD 650/52, SD 800, SD 808, and SD 810, TOCTOU condition could lead to a buffer overflow in function playready_reader_bind().
In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Mobile SD 410/12, SD 617, SD 650/52, SD 800, SD 808, and SD 810, in the function "Certificate_CreateWithBuffer" in the QSEE app TQS, in case of memory allocation failure, we free the memory and return the pointer without setting it to NULL.
In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Automobile, Snapdragon Mobile, and Snapdragon Wear MSM8909W, SD 210/SD 212/SD 205, SD 400, SD 410/12, SD 425, SD 430, SD 450, SD 615/16/SD 415, SD 617, SD 625, SD 650/52, SD 800, SD 808, SD 810, SD 820, and SD 820A, a buffer overread in Playready may occur due to lack of input validation of the buffer size provided by HLOS.
In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Automobile, Snapdragon Mobile, and Snapdragon Wear IPQ4019, MDM9206, MDM9607, MDM9650, MSM8909W, SD 210/SD 212/SD 205, SD 400, SD 410/12, SD 425, SD 430, SD 450, SD 615/16/SD 415, SD 617, SD 625, SD 650/52, SD 808, SD 810, SD 820, SD 820A, SD 835, SD 845, and SD 850, DRM provisioning mechanisms used in QSEE applications have a feature to prevent further provisioning. This is done by creating an SFS file called 'finalize_prov_flag.data' at the end of provisioning. When this feature is enabled, provisioning calls check for the existence of the file in order to decide whether to do provisioning or not. Current implementation allows provisioning without sufficient checks.
