MiCode FileExplorer SwiFTP Server Authentication Bypass

MiCode FileExplorer contains an authentication bypass vulnerability in the embedded SwiFTP FTP server component that allows network attackers to log in without valid credentials. Attackers can send arbitrary username and password combinations to the PASS command handler, which unconditionally grants access and allows listing, reading, writing, and deleting files exposed by the FTP server. The MiCode/Explorer open source project has reached end-of-life status.

The msm gpu driver for custom Linux kernels on the Xiaomi perseus-p-oss MIX 3 device through 2018-11-26 has an integer overflow and OOPS because of missing checks of the count argument in _sde_debugfs_conn_cmd_tx_write in drivers/gpu/drm/msm/sde/sde_connector.c. This is exploitable for a device crash via a syscall by a crafted application on a rooted device.

The msm gpu driver for custom Linux kernels on the Xiaomi perseus-p-oss MIX 3 device through 2018-11-26 has an integer overflow and OOPS because of missing checks of the count argument in sde_evtlog_filter_write in drivers/gpu/drm/msm/sde_dbg.c. This is exploitable for a device crash via a syscall by a crafted application on a rooted device.

drivers/leds/leds-aw2023.c in the led driver for custom Linux kernels on the Xiaomi Redmi 6pro daisy-o-oss phone has several integer overflows because of a left-shifting operation when the right-hand operand can be equal to or greater than the integer length. This can be exploited by a crafted application for denial of service.

The ft5x46 touchscreen driver for custom Linux kernels on the Xiaomi perseus-p-oss MIX 3 device through 2018-11-26 has an integer overflow and OOPS because of missing checks of the size argument in tpdbg_write in drivers/input/touchscreen/ft5x46/ft5x46_ts.c. This is exploitable for a device crash via a syscall by a crafted application on a rooted device.
