Disponibili per il download i primi aggiornamenti che riguardano la sicurezza per Ubuntu 11.04 Natty Narwhal.

Como sappiamo da Ubuntu 9.04 Jaunty Jackalope in poi questi aggiornamenti con buon criterio sono rilasciati con una cadenza settimanale da Canonical.

Specificamente gli aggiornamenti riguardano le librerie Perl, il server VNC per Gnome e la utility di masterizzazione installata di default.

Perl è un linguaggio di programmazione ad alto livello, dinamico, procedurale e interpretato, creato nel 1987 da Larry Wall. Perl ha un singolare insieme di funzionalità ereditate da C, scripting shell Unix (sh), Awk, sed e in diversa misura da molti altri linguaggi di programmazione, compresi alcuni linguaggi funzionali.

Benché sia molto noto come linguaggio per lo sviluppo di CGI, Perl è stato creato inizialmente come ausilio ai sistemisti, come linguaggio di manipolazione di testo e file. Infatti è anche detto Practical Extraction and Report Language, ma questo è un acronimo assegnato dopo la creazione del nome o, in inglese, un "backronym". Pertanto secondo la documentazione stessa di Perl, non vi si dovrebbe mai riferire come "PERL", ma come "Perl" o "perl" a seconda che si intenda il linguaggio in quanto tale o una specifica implementazione rispettivamente. È anzi questa un'informazione utilizzata negli ambienti perlistici per distinguere "chi è del giro" da chi non lo è.


In dettaglio:


Shared Perl Library:


Cambiamenti per le versioni:
5.10.1-17ubuntu4
5.10.1-17ubuntu4.1


Versione 5.10.1-17ubuntu4.1:


  * SECURITY UPDATE: multiple intended restriction bypasses in Safe.pm
    - debian/patches/fixes/CVE-2010-1447.diff: update Safe.pm to version
      2.29 to fix multiple issues.
    - debian/patches/series: disable superseded fixes/safe-upgrade.diff.
    - CVE-2010-1447
  * SECURITY UPDATE: taint protection bypass via missing taint attributes
    - debian/patches/fixes/CVE-2011-1487.diff: put taint logic at the end
      of pp_* functions.
    - CVE-2011-1487


This package is required by programs which embed a Perl interpreter to ensure that the correct version of `perl-base' is installed.
It additionally contains the shared Perl library on architectures where the perl binary is linked to libperl.a (currently only i386, for performance reasons).


In other cases the actual library is in the `perl-base' package.

An interpreted scripting language, known among some as "Unix's Swiss Army Chainsaw".
Perl is optimised for scanning arbitrary text files and system administration.
It has built-in extended regular expression matching and replacement, a data-flow mechanism to improve security with setuid scripts and is extensible via modules that can interface to C libraries.


Minimal Perl System.

Perl is a scripting language used in many system scripts and utilities.
This package provides a Perl interpreter and the small subset of the standard run-time library required to perform basic tasks. For a full Perl installation, install "perl" (and its dependencies, "perl-modules" and "perl-doc").

Core Perl Modules.

      of pp_* functions.
    - CVE-2011-1487


Architecture independent Perl modules.
These modules are part of Perl and required if the `perl' package is installed.
Note that this package only exists to save archive space and should be considered an internal implementation detail of the `perl' package. Other packages should not depend on `perl-modules' directly, they should use `perl' (which depends on `perl-modules') instead.

Create a startup disk using a Cd or disk image (common files).

Startup Disk Creator converts a USB key or SD card into a volume from which you can start up and run Ubuntu. You can also store files and settings in any space left over.
The program also works for Debian, or any other Debian-based OS for which you have a CD or .iso image.
This package contains backend engine and common data files used by frontends.
