Notes

[jessie] - radare2 <no-dsa> (Minor issue)
https://github.com/radare/radare2/issues/6816
Fixed by: https://github.com/radare/radare2/commit/1ea23bd6040441a21fbcfba69dce9a01af03f989
Although the respective new versions were only introduced in 0.10.3
The NULL pointer dereferences are still triggerable, via the shown
vector and seen under valgrind. It might be disputable if that is the
same vulnerability though.
