match: avoid crash if subject NULL and PCRE2_ZERO_TERMINATED ( #53 )
...
* pcre2_match: avoid crash if subject NULL and PCRE2_ZERO_TERMINATED
When length of subject is PCRE2_ZERO_TERMINATED strlen is used
to calculate its size, which will trigger a crash if subject is
also NULL.
Move the NULL check before strlen on it would be used, and make
sure or dependent variables are set after the NULL validation
as well.
While at it, fix a typo in a debug flag in the same file, which
is otherwise unrelated and make sure the full section of constrain
checks can be identified clearly using the leading comment alone.
* pcre2_dfa_match: avoid crash if subject NULL and PCRE2_ZERO_TERMINATED
When length of subject is PCRE2_ZERO_TERMINATED strlen is used
to calculate its size, which will trigger a crash if subject is
also NULL.
Move the NULL check before the detection for subject sizes to
avoid this issue.
* pcre2_substitute: avoid crash if subject or replacement are NULL
The underlying pcre2_match() function will validate the subject if
needed, but will crash when length is PCRE2_ZERO_TERMINATED or if
subject == NULL and pcre2_match() is not being called because
match_data was provided.
The replacement parameter is missing NULL checks, and so currently
allows for an equivalent response to "" if rlength == 0.
Restrict all other cases to avoid strlen(NULL) crashes in the same
way that is done for subject, but also make sure to reject invalid
length values as early as possible.
