Project functions overview

The following table shows data about each function in the project. The functions included in this table correspond to all functions that exist in the executables of the fuzzers. As such, there may be functions that are from third-party libraries.

For further technical details on the meaning of columns in the below table, please see the Glossary .

Fuzzer: phonefuzz

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Runtime coverage analysis

Covered functions
619
Functions that are reachable but not covered
1999
Reachable functions
3230
Percentage of reachable functions covered
38.11%
NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Analyses and suggestions

Optimal target analysis

Remaining optimal interesting functions

The following table shows a list of functions that are optimal targets. Optimal targets are identified by finding the functions that in combination, yield a high code coverage.

Func name Functions filename Arg count Args Function depth hitcount instr count bb count cyclomatic complexity Reachable functions Incoming references total cyclomatic complexity Unreached complexity
icu_66::RegexPattern::matches(icu_66::UnicodeStringconst&,icu_66::UnicodeStringconst&,UParseError&,UErrorCode&) /src/icu/source/i18n/repattrn.cpp 4 ['N/A', 'N/A', 'N/A', 'N/A'] 35 0 87 12 5 2192 0 10218 10191
icu_66::RuleBasedBreakIterator::RuleBasedBreakIterator(icu_66::UnicodeStringconst&,UParseError&,UErrorCode&) /src/icu/source/common/rbbi.cpp 4 ['N/A', 'N/A', 'N/A', 'N/A'] 33 0 134 23 20 1474 0 5887 1498

Implementing fuzzers that target the above functions will improve reachability such that it becomes:

Functions statically reachable by fuzzers
43.0%
3267 / 7660
Cyclomatic complexity statically reachable by fuzzers
48.0%
21108 / 43914

All functions overview

If you implement fuzzers for these functions, the status of all functions in the project will be:

Func name Functions filename Args Function call depth Reached by Fuzzers Fuzzers runtime hit Func lines hit % I Count BB Count Cyclomatic complexity Functions reached Reached by functions Accumulated cyclomatic complexity Undiscovered complexity

Fuzz engine guidance

This sections provides heuristics that can be used as input to a fuzz engine when running a given fuzz target. The current focus is on providing input that is usable by libFuzzer.

/src/libphonenumber/cpp/build/../test/phonenumbers/fuzz_phone.cc

Dictionary

Use this with the libFuzzer -dict=DICT.file flag


Fuzzer function priority

Use one of these functions as input to libfuzzer with flag: -focus_function name 

-focus_function=['i18n::phonenumbers::AsYouTypeFormatter::InputDigitWithOptionToRememberPosition(int, bool, std::__1::basic_string, std::__1::allocator >*)', 'i18n::phonenumbers::PhoneNumberUtil::PhoneNumberUtil()', 'i18n::phonenumbers::PhoneNumberMatcher::Find(int, i18n::phonenumbers::PhoneNumberMatch*)', 'i18n::phonenumbers::PhoneNumberUtil::PhoneNumberUtil()', 'i18n::phonenumbers::ShortNumberInfo::ShortNumberInfo()', 'i18n::phonenumbers::ShortNumberInfo::ShortNumberInfo()', 'i18n::phonenumbers::PhoneNumberUtil::ParseHelper(std::__1::basic_string, std::__1::allocator > const&, std::__1::basic_string, std::__1::allocator > const&, bool, bool, i18n::phonenumbers::PhoneNumber*) const', 'i18n::phonenumbers::PhoneNumberUtil::Format(i18n::phonenumbers::PhoneNumber const&, i18n::phonenumbers::PhoneNumberUtil::PhoneNumberFormat, std::__1::basic_string, std::__1::allocator >*) const', 'i18n::phonenumbers::PhoneNumberUtil::PhoneNumberUtil()', 'i18n::phonenumbers::NumberFormat::_internal_set_domestic_carrier_code_formatting_rule(std::__1::basic_string, std::__1::allocator > const&)']

Files and Directories in report

This section shows which files and directories are considered in this report. The main reason for showing this is fuzz introspector may include more code in the reasoning than is desired. This section helps identify if too many files/directories are included, e.g. third party code, which may be irrelevant for the threat model. In the event too much is included, fuzz introspector supports a configuration file that can exclude data from the report. See the following link for more information on how to create a config file: link
