The current problem is with Ruby, but it seems plausible that other languages could be affected as well. If Ruby's YAML parser stuck to just deserializing into 'boring' data structures (strings, numbers, booleans, arrays, and hashes), this security problem would not occur. The issue is that it can deserialize an arbitrary Ruby object of any class, and set its attributes.Does the Perl YAML parser have any similar facility? ___ Boston-pm mailing list Boston-pm@mail.pm.org http://mail.pm.org/mailman/listinfo/boston-pm

[Boston.pm] Non-matching regexp doesn't set $1 to undef. Should it?
If I try to match a regular expression that contains parentheses, and
the match fails, shouldn't $1 be set to undef rather than keeping
whatever value it had before? The following program demonstrates what
looks to me like very strange behavior. Adding local $1 = undef; in
the position shown did not change this behavior.
---
#!/usr/bin/perl -w
use strict;
sub1(There are 100 words.);
sub sub1 {
my $s = shift;
$s =~ /There are (\d+) words./;
print sub1 (before call): \$1=$1\n;
sub2($s);
print sub1 (after call): \$1=$1\n;
}
sub sub2 {
my $s = shift;
# local $1 = undef; --- Adding this has no apparent effect.
print sub2 (before match): \$1=$1\n;
$s =~ /There are ([a-z]+) words./;
print sub2 (after match): \$1=$1\n;
}

The output:
sub1 (before call): $1=100
