* VMS patch for duplicate env entriesmaint-5.20Craig A. Berry2016-02-131-1/+3

* remove duplicate environment variables from environTony Cook2016-02-131-2/+49
| | | | | | | | | | | | | | | | | | | If we see duplicate environment variables while iterating over environ[]: a) make sure we use the same value in %ENV that getenv() returns. Previously on a duplicate, %ENV would have the last entry for the name from environ[], but a typical getenv() would return the first entry. Rather than assuming all getenv() implementations return the first entry explicitly call getenv() to ensure they agree. b) remove duplicate entries from environ Previously if there was a duplicate definition for a name in environ[] setting that name in %ENV could result in an unsafe value being passed to a child process, so ensure environ[] has no duplicates.

| | | | | | | | | | Previously the unix specific XS implementation of canonpath() would return an untainted path when supplied a tainted path. For the empty string case, newSVpvs() already sets taint as needed on its result. This issue was assigned CVE-2015-8607. [perl #126862]

| | | | | | | The change in question (0b45ede/71622e4) is in 5.20.3, but its effect is less significant here than in 5.21 and isn't worth mentioning. Thanks to SHIRAKATA Kentaro for the spot.

* [perl #123893] Fix hang with "@{"Father Chrysostomos2015-08-282-5/+17
| | | | | | | | | | | | | | | | | | | | | | | Commit v5.21.8-320-ge47d32d stopped code interpolated into quote-like operators from reading more lines of input, by making lex_next_chunk ignore the open filehandle and return false. That causes this block under case 0 in yylex to loop: if (!lex_next_chunk(fake_eof)) { CopLINE_dec(PL_curcop); s = PL_bufptr; TOKEN(';'); /* not infinite loop because rsfp is NULL now */ } (rsfp is not null there.) This commit makes it check for quote-like operators above, in the same place where it checks whether the file is open, to avoid falling through to this code that can loop. This changes the syntax errors for a couple of cases recently added to t/op/lex.t, though I think the error output is now more consis- tent overall.

* [perl #123712] Don’t check sub_inwhatFather Chrysostomos2015-08-282-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PL_sublex_info.sub_inwhat (in the parser struct) is a temporary spot to store the value of PL_lex_inwhat (also in the parser struct) when a sub-lexing scope (for a quote-like operator) is entered. PL_lex_inwhat is localised, and the value is copied from its temporary spot (sub_inwhat) into PL_lex_inwhat. The PL_sublex_info.sub_inwhat was not localised, but instead the value was set to 0 when a sub-lexing scope was exited. This value was being used, in a couple of places, to determine whether we were inside a quote-like operator. But because the value is not localised, it can be wrong when it is set to 0, if we have nested lexing scopes. So this ends up crashing for the same reason described in e47d32dcd5: echo -n '/$a[m||/<<a' | ./miniperl perl-5.005_02-1816-g09bef84 added the first use of PL_sublex_info.sub_inwhat to determine whether we are in a quote-like operator. (Later it got shifted around.) I copied that in e47d32dcd5 (earlier today), because I assumed the logic was correct. Other parts of the code use PL_lex_inwhat, which is already localised, as I said, and does not suffer this problem. If we do not check PL_sublex_info.sub_inwhat to see if we are in a quote-like construct, then we don’t need to clear it on lexing scope exit.

* [perl #123712] Fix /$a[/ parsingFather Chrysostomos2015-08-282-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The parser used to read more lines of input when parsing code interpo- lated into quote-like operators, under some circumstance. This would result in code like this working, even though it should be a syn- tax error: s||${s/.*/|; /s}Just another Perl hacker, print "${;s/.*/Just an"; other Perl hacker, /s} die or return; print While this was harmless, other cases, like /$a[/<<a with no trailing newline, would cause unexpected internal state that did not meet the reasonable assumptions made by S_scan_heredoc, resulting in a crash. The simplest fix is to modify the function that reads more input, namely, lex_next_chunk, and prevent it from reading more lines of input from inside a quote-like operator. (The alternative would be to modify all the calls to lex_next_chunk, and make them conditional.) That breaks here-doc parsing for things like s//<<EOF/, but the LEX_NO_TERM flag to lex_next_chunk is used only by the here-doc parser, so lex_next_chunk can make an exception if it is set.
