This update of Perl fixes a heap based buffer overflow in the decode_xs() function (CVE-2011-2939, bnc#728662).

The remote Solaris system is missing necessary patches to address security updates :

  - Race condition in the rmtree function in the File::Path     module in Perl 5.6.1 and 5.8.4 sets read/write     permissions for the world, which allows local users to     delete arbitrary files and directories, and possibly     read files and directories, via a symlink attack.
    (CVE-2004-0452)

  - Buffer overflow in the PerlIO implementation in Perl     5.8.0, when installed with setuid support (sperl),     allows local users to execute arbitrary code by setting     the PERLIO_DEBUG variable and executing a Perl script     whose full pathname contains a long directory tree.
    (CVE-2005-0156)

  - Race condition in the rmtree function in File::Path.pm     in Perl before 5.8.4 allows local users to create     arbitrary setuid binaries in the tree being deleted, a     different vulnerability than CVE-2004-0452.
    (CVE-2005-0448)

  - Untrusted search path vulnerability in Perl before     5.8.7-r1 on Gentoo Linux allows local users in the     portage group to gain privileges via a malicious shared     object in the Portage temporary build directory, which     is part of the RUNPATH. (CVE-2005-4278)

  - Integer overflow in the regular expression engine in     Perl 5.8.x allows context-dependent attackers to cause a     denial of service (stack consumption and application     crash) by matching a crafted regular expression against     a long string. (CVE-2010-1158)

  - Off-by-one error in the decode_xs function in     Unicode/Unicode.xs in the Encode module before 2.44, as     used in Perl before 5.15.6, might allow     context-dependent attackers to cause a denial of service     (memory corruption) via a crafted Unicode string, which     triggers a heap-based buffer overflow. (CVE-2011-2939)

  - CGI.pm module before 3.63 for Perl does not properly     escape newlines in (1) Set-Cookie or (2) P3P headers,     which might allow remote attackers to inject arbitrary     headers into responses from applications that use     CGI.pm. (CVE-2012-5526)

A heap-based buffer overflow flaw was found in the way Perl decoded Unicode strings. An attacker could create a malicious Unicode string that, when decoded by a Perl program, would cause the program to crash or, potentially, execute arbitrary code with the permissions of the user running the program. (CVE-2011-2939)

It was found that the 'new' constructor of the Digest module used its argument as part of the string expression passed to the eval() function. An attacker could possibly use this flaw to execute arbitrary Perl code with the privileges of a Perl program that uses untrusted input as an argument to the constructor. (CVE-2011-3597)

Update to version 1.1.4 of icedtea-web to fix the following issues :

  - CVE-2011-3377: IcedTea-Web: second-level domain     subdomains and suffix domain SOP bypass

  - PR778: Jar download and server certificate verification     deadlock

The remote host is affected by the vulnerability described in GLSA-201401-11 (Perl, Locale Maketext Perl module: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Perl and       Locale::Maketext Perl module. Please review the CVE identifiers       referenced below for details.
  Impact :

    A context-dependent attacker could possibly execute arbitrary code with       the privileges of the process or cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

    All Perl users should upgrade to these updated packages, which contain     backported patches to correct these issues. All running Perl programs must     be restarted for this update to take effect.

    Note: An error in the corresponding spec file resulted in an incorrect version     number being cited for the perl-Compress-Raw-Zlib package in the original     RHSA-2011:1424 advisory. For more information please review     https://access.redhat.com/solutions/239773.

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2012-353:01 advisory.

    Perl is a high-level programming language with roots in C, sed, awk and shell scripting. Perl is good at     handling processes and files, and is especially good at handling text. Perl's hallmarks are practicality     and efficiency. While it is used to do a lot of different things, Perl's most common applications are     system administration utilities and web programming. A large proportion of the CGI scripts on the web are     written in Perl. You need the perl package installed on your system so that your system can handle Perl     scripts.
    Install this package if you want to program in Perl or enable your system to handle Perl scripts.
    Security issues fixed with this release:
    CVE-2011-2939     Off-by-one error in the decode_xs function in Unicode/Unicode.xs in the Encode module before 2.44, as used     in Perl before 5.15.6, might allow context-dependent attackers to cause a denial of service (memory     corruption) via a crafted Unicode string, which triggers a heap-based buffer overflow.
    CVE-2011-3597     Eval injection in the Digest module before 1.17 for Perl allows context-dependent attackers to execute     arbitrary commands via the new constructor.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Off-by-one error in the decode_xs function in Unicode/Unicode.xs in the Encode module before 2.44, as used     in Perl before 5.15.6, might allow context-dependent attackers to cause a denial of service (memory     corruption) via a crafted Unicode string, which triggers a heap-based buffer overflow. (CVE-2011-2939)

Note that Nessus relies on the presence of the package as reported by the vendor.
