+Subject: [PATCH] perl: fix CVE-2016-6185
+MIME-Version: 1.0
+
+Don't let XSLoader load relative paths
+
+[rt.cpan.org #115808]
+
+The logic in XSLoader for determining the library goes like this:
+
+    my $c = () = split(/::/,$caller,-1);
+    $modlibname =~ s,[\\/][^\\/]+$,, while $c--;    # Q&D basename
+    my $file = "$modlibname/auto/$modpname/$modfname.bundle";
+
+(That last line varies by platform.)
+
+$caller is the calling package.  $modlibname is the calling file.  It
+removes as many path segments from $modlibname as there are segments
+in $caller.  So if you have Foo/Bar/XS.pm calling XSLoader from the
+Foo::Bar package, the $modlibname will end up containing the path in
+@INC where XS.pm was found, followed by "/Foo".  Usually the fallback
+to Dynaloader::bootstrap_inherit, which does an @INC search, makes
+things Just Work.
+
+But if our hypothetical Foo/Bar/XS.pm actually calls
+XSLoader::load from inside a string eval, then path ends up being
+"(eval 1)/auto/Foo/Bar/Bar.bundle".
+
+So if someone creates a directory named '(eval 1)' with a naughty
+binary file in it, it will be loaded if a script using Foo::Bar is run
+in the parent directory.
+
+This commit makes XSLoader fall back to Dynaloader's @INC search if
+the calling file has a relative path that is not found in @INC.
+

+
+ensure File::Spec::canonpath() preserves taint
+
+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]
