The remote host is affected by the vulnerability described in GLSA-201410-02 (Perl, Perl Locale-Maketext module: Multiple vulnerabilities)

    Two vulnerabilities have been reported in the Locale-Maketext module for       Perl, which can be exploited by malicious users to compromise an       application using the module.
    The vulnerabilities are caused due to the &ldquo;_compile()&rdquo; function not       properly sanitising input, which can be exploited to inject and execute       arbitrary Perl code.
  Impact :

    A remote 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.

Perl was updated to fix 3 security issues :

  - fix rehash denial of service (compute time) [bnc#804415]     [CVE-2013-1667]

  - improve CGI crlf escaping [bnc#789994] [CVE-2012-5526]

  - sanitize input in Maketext.pm to avoid code injection     [bnc#797060] [CVE-2012-6329]

In openSUSE 12.1 also the following non-security bug was fixed :

  - fix IPC::Open3 bug when '-' is used [bnc#755278]

The version of Perl on the remote host is affected by a code execution vulnerability. 

The _compile function in Locale::Maketext in Perl before 5.17.7 does not properly handle backslashes and fully qualified method names during compilation of bracket notation. This could allow context- dependent attackers to execute arbitrary commands via crafted input.

It was discovered that Perl's Locale::Maketext module incorrectly handled backslashes and fully qualified method names. An attacker could possibly use this flaw to execute arbitrary code when an application used untrusted templates.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A heap overflow flaw was found in Perl. If a Perl application allowed user input to control the count argument of the string repeat operator, an attacker could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2012-5195)

A denial of service flaw was found in the way Perl's rehashing code implementation, responsible for recalculation of hash keys and redistribution of hash content, handled certain input. If an attacker supplied specially crafted input to be used as hash keys by a Perl application, it could cause excessive memory consumption.
(CVE-2013-1667)

It was found that the Perl CGI module, used to handle Common Gateway Interface requests and responses, incorrectly sanitized the values for Set-Cookie and P3P headers. If a Perl application using the CGI module reused cookies values and accepted untrusted input from web browsers, a remote attacker could use this flaw to alter member items of the cookie or add new items. (CVE-2012-5526)

It was found that the Perl Locale::Maketext module, used to localize Perl applications, did not properly handle backslashes or fully-qualified method names. An attacker could possibly use this flaw to execute arbitrary Perl code with the privileges of a Perl application that uses untrusted Locale::Maketext templates.
(CVE-2012-6329)

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2013-0685 advisory.

    - Resolves: #915692 - CVE-2012-5526 (newline injection due to improper CRLF       escaping in Set-Cookie and P3P headers)
    - Resolves: #915692 - CVE-2012-6329 (possible arbitrary code execution via       Locale::Maketext)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated perl packages fix security vulnerability :

It was discovered that Perl's 'x' string repeat operator is vulnerable to a heap-based buffer overflow. An attacker could use this to execute arbitrary code (CVE-2012-5195).

The _compile function in Maketext.pm in the Locale::Maketext implementation in Perl before 5.17.7 does not properly handle backslashes and fully qualified method names during compilation of bracket notation, which allows context-dependent attackers to execute arbitrary commands via crafted input to an application that accepts translation strings from users (CVE-2012-6329).

In order to prevent an algorithmic complexity attack against its hashing mechanism, perl will sometimes recalculate keys and redistribute the contents of a hash. This mechanism has made perl robust against attacks that have been demonstrated against other systems. Research by Yves Orton has recently uncovered a flaw in the rehashing code which can result in pathological behavior. This flaw could be exploited to carry out a denial of service attack against code that uses arbitrary user input as hash keys. Because using user-provided strings as hash keys is a very common operation, we urge users of perl to update their perl executable as soon as possible.
Updates to address this issue have bene pushed to main-5.8, maint-5.10, maint-5.12, maint-5.14, and maint-5.16 branches today.
Vendors* were informed of this problem two weeks ago and are expected to be shipping updates today (or otherwise very soon) (CVE-2013-1667).

According to its version number, the instance of TWiki running on the remote host is affected by multiple security vulnerabilities :

  - The '%MAKETEXT{}%' variable fails to properly sanitize     user-supplied input. A remote attacker can exploit this     issue to execute arbitrary shell commands on the remote     host subject to the privileges of the web server user.
