	%X We present a taint analysis that can automatically detect
when string operations result in a string that is free of taints, where
all the tainted patterns have been removed. This is an improvement
on the conservative behavior of previous taint analyzers, where a
string operation on a tainted string always leads to a tainted string
unless the operation is manually marked as a sanitizer. The taint
analysis is built on top of a string analysis that uses finite state
automata to approximate the sets of values that string variables can
take during the execution of a program. The proposed approach has
been implemented as an extension of FlowDroid and experimental
results show that the resulting taint analyzer is much more precise
than the original FlowDroid.
