The suidperl is neither built nor +installed by default. As of August the 20th 2000 the only known +vulnerable platform is Linux, most likely all Linux distributions. +The CERT and various vendors have been alerted about the vulnerability. + +The problem was caused by Perl trying to report a suspected security +exploit attempt using an external program, /bin/mail. In Linux +platforms the /bin/mail program had an undocumented feature which gave +access to a root shell, resulting in a serious compromise, instead of +reporting the exploit attempt. If you don't have /bin/mail or if you +have 'safe suid scripts' or if you haven't installed the suidperl, you +are safe. + +The exploit attempt reporting feature has been completely removed from +the Perl 5.7.0 release, so that particular vulnerability isn't there +anymore. However, further security vulnerabilities are, +unfortunately, always possible. The suidperl code is being reviewed +and if deemed too risky to continue being supported, in the extreme +case it may be completely removed in future releases. In any case, +suidperl should only be used by security experts who know exactly what +they are doing and why are they using suidperl instead of some other solution. +A good tool for similar needs is sudo: http://www.courtesan.com/sudo/ + +=head1 Performance Enhancements + +map() that changes the size of the list should now work faster. =head1 Installation and Configuration Improvements +=head2 INSTALL now explains 64-bit configuration. + +In some platforms Perl can be configured to use 64-bit integers, +allowing 4 billion times better...sorry, switched accidentally to +marketdroid mode for a moment in there. (In platforms which are +natively 64-bit this makes no difference.) + +=head2 Policy.sh policy change + +If you are reusing a Policy.sh file (see INSTALL) and you use +Configure -Dprefix=/foo/bar and in the old Policy $prefix eq +$siteprefix and $prefix eq $vendorprefix, all of them will now +be changed to the new prefix, /foo/bar. (Previously only $prefix +did change.) If you do not like this new behaviour, specify +prefix, siteprefix, and vendorprefix explicitly. + +=head2 Additional Library Locations + +A new optional location for Perl libraries, otherlibdirs, is available. +It can be used for example for vendor add-ons without disturbing Perl's +own library directories. + =head2 gcc automatically tried if 'cc' does not seem to be working In many platforms the vendor-supplied 'cc' is too stripped-down to @@ -25,35 +485,670 @@ build Perl (basically, the 'cc' doesn't do ANSI C). If this seems to be the case and the 'cc' does not seem to be the GNU C compiler 'gcc', an automatic attempt is made to find and use 'gcc' instead. -=head1 Platform specific changes +=head2 If gcc seems to be from from a different operating system release ... + +gcc needs to closely track the operating system release because gcc +wants to have its own versions of the operating system header files +fixed to be clean enough for gcc's tastes. Therefore using a gcc +compiled for a different release of the operating system is often a +bad idea. If Configure can find out the operating system release that +was used to compile the gcc and that release is different from the one +being used now, gcc gives a clearly visible warning that trouble may +lie ahead. + +=head2 If no binary compatibilty with 5.005 wanted, no 5.005 modules, either + +If no binary compatibility with the 5.005 release is wanted, Configure +does not suggest including the 5.005 modules in the @INC. + +=head2 Configuration and Installation fixes + +=over 4 + +=item * + +Configure C<-S> can now run non-interactively + +=item * + +configure.gnu now works with options with whitespace in them + +=item * + +installperl now outputs everything to STDERR + +=item * + +$Config{byteorder} is now computed dynamically (this is more robust +with "fat binaries" where an executable image contains binaries for +more than one binary platform.) + +=back + +=head1 Platform Specific Changes and Fixes + +=head2 BSDI 4.* + +Perl now works on post-4.0 BSD/OSes. + +=head2 All BSDs + +Setting the C<$0> now works (as much as possible, see perlvar for details). + +=head2 Cygwin + +=over 4 + +=item * + +Numerous updates; currently synchronized with Cygwin 1.1.4. + +=back + +=head2 EPOC + +EPOC update after Perl 5.6.0.

Currently there is no good solution for the problem +but Configure now stores the flags and libraries that effect the +largefileness to the %Config hash, the extensions that are having +problems can try configuring themselves without the largefileness. +This is admittedly not a clean solution. + =head1 Obsolete Diagnostics =head1 Reporting Bugs @@ -81,8 +1176,8 @@ The F and F files for copyright information. =head1 HISTORY -Written by Gurusamy Sarathy >, with many -contributions from The Perl Porters. +Written by Jarkko Hietaniemi >, with many contributions +from The Perl Porters and Perl Users submitting feedback and patches.
