0.0.9

New Queries

• Added a new query, cpp/open-call-with-mode-argument, to detect when open or openat is called with the O_CREAT or O_TMPFILE flag but when the mode argument is omitted.

Minor Analysis Improvements

• The "Cleartext transmission of sensitive information" (cpp/cleartext-transmission) query has been further improved to reduce false positive results, and upgraded from medium to high precision.
• The "Cleartext transmission of sensitive information" (cpp/cleartext-transmission) query now finds more results, where a password is stored in a struct field or class member variable.
• The cpp/cleartext-storage-file query has been improved, removing false positives where data is written to a standard output stream.
• The cpp/cleartext-storage-buffer query has been updated to use the semmle.code.cpp.dataflow.TaintTracking library.
• The cpp/world-writable-file-creation query now only detects open and openat calls with the O_CREAT or O_TMPFILE flag.
