CVE-2010-2253 (2010-07-06)

lwp-download in libwww-perl before 5.835 does not reject downloads to filenames that begin with a . (dot) character, which allows remote servers to create or overwrite files via (1) a 3xx redirect to a URL with a crafted filename or (2) a Content-Disposition header that suggests a crafted filename, and possibly execute arbitrary code as a consequence of writing to a dotfile in a home directory.

LWP::Protocol::file can open existent file from file:// scheme. However, current version of LWP uses open FILEHANDLE,EXPR and it has ability to execute arbitrary command

CVE-2011-0633 (2011-01-20)

The Net::HTTPS module in libwww-perl (LWP) before 6.00, as used in WWW::Mechanize, LWP::UserAgent, and other products, when running in environments that do not set the If-SSL-Cert-Subject header, does not enable full validation of SSL certificates by default, which allows remote attackers to spoof servers via man-in-the-middle (MITM) attacks involving hostnames that are not properly validated.

NAME

WWW::RobotRules::AnyDBM_File - Persistent RobotRules

SYNOPSIS

require WWW::RobotRules::AnyDBM_File;
require LWP::RobotUA;

# Create a robot useragent that uses a diskcaching RobotRules
my $rules = new WWW::RobotRules::AnyDBM_File 'my-robot/1.0', 'cachefile';
my $ua = new WWW::RobotUA 'my-robot/1.0', 'me@foo.com', $rules;

# Then just use $ua as usual
$res = $ua->request($req);

DESCRIPTION

This is a subclass of WWW::RobotRules that uses the AnyDBM_File package to implement persistent diskcaching of robots.txt and host visit information.

The constructor (the new() method) takes an extra argument specifying the name of the DBM file to use. If the DBM file already exists, then you can specify undef as agent name as the name can be obtained from the DBM database.
