According to the versions of the perl packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The XSLoader::load method in XSLoader in Perl does not     properly locate .so files when called in a string eval,     which might allow local users to execute arbitrary code     via a Trojan horse library under the current working     directory.(CVE-2016-6185)

  - The Dumper method in Data::Dumper before 2.154, as used     in Perl 5.20.1 and earlier, allows context-dependent     attackers to cause a denial of service (stack     consumption and crash) via an Array-Reference with many     nested Array-References, which triggers a large number     of recursive calls to the DD_dump     function.(CVE-2014-4330)

According to the versions of the perl packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The (1) S_reghop3, (2) S_reghop4, and (3)     S_reghopmaybe3 functions in regexec.c in Perl before     5.24.0 allow context-dependent attackers to cause a     denial of service (infinite loop) via crafted utf-8     data, as demonstrated by 'a\x80.'(CVE-2015-8853)

  - The XSLoader::load method in XSLoader in Perl does not     properly locate .so files when called in a string eval,     which might allow local users to execute arbitrary code     via a Trojan horse library under the current working     directory.(CVE-2016-6185)

This fixes CVE-2016-6185 vulnerability (do not let XSLoader load relative paths).

Multiple vulnerabilities were discovered in the implementation of the Perl programming language. The Common Vulnerabilities and Exposures project identifies the following problems :

CVE-2016-1238

John Lightsey and Todd Rinaldo reported that the opportunistic loading of optional modules can make many programs unintentionally load code from the current working directory (which might be changed to another directory without the user realising) and potentially leading to privilege escalation, as demonstrated in Debian with certain combinations of installed packages.

The problem relates to Perl loading modules from the includes directory array ('@INC') in which the last element is the current directory ('.'). That means that, when 'perl' wants to load a module (during first compilation or during lazy loading of a module in run- time), perl will look for the module in the current directory at the end, since '.' is the last include directory in its array of include directories to seek. The issue is with requiring libraries that are in '.' but are not otherwise installed.

With this update several modules which are known to be vulnerable are updated to not load modules from current directory.

Additionally the update allows configurable removal of '.' from @INC in /etc/perl/sitecustomize.pl for a transitional period. It is recommended to enable this setting if the possible breakage for a specific site has been evaluated.
Problems in packages provided in Debian resulting from the switch to the removal of '.' from @INC should be reported to the Perl maintainers at perl@packages.debian.org .

CVE-2016-6185

It was discovered that XSLoader, a core module from Perl to dynamically load C libraries into Perl code, could load shared library from incorrect location. XSLoader uses caller() information to locate the .so file to load. This can be incorrect if XSLoader::load() is called in a string eval. An attacker can take advantage of this flaw to execute arbitrary code.

For Debian 7 'Wheezy', these problems have been fixed in version 5.14.2-21+deb7u4.

We recommend that you upgrade your perl packages.

The remote NewStart CGSL host, running version MAIN 6.06, has perl packages installed that are affected by multiple vulnerabilities:

  - Heap-based buffer overflow in the pack function in Perl before 5.26.2 allows context-dependent attackers     to execute arbitrary code via a large item count. (CVE-2018-6913)

  - Directory traversal vulnerability in the Archive::Tar Perl module 1.36 and earlier allows user-assisted     remote attackers to overwrite arbitrary files via a TAR archive that contains a file whose name is an     absolute path or has .. sequences. (CVE-2007-4829)

  - The rmtree function in lib/File/Path.pm in Perl 5.10 does not properly check permissions before performing     a chmod, which allows local users to modify the permissions of arbitrary files via a symlink attack, a     different vulnerability than CVE-2005-0448 and CVE-2004-0452. (CVE-2008-2827)

  - Perl 5.10.1 allows context-dependent attackers to cause a denial of service (application crash) via a     UTF-8 character with a large, invalid codepoint, which is not properly handled during a regular-expression     match. (CVE-2009-3626)

  - The bsd_glob function in the File::Glob module for Perl before 5.14.2 allows context-dependent attackers     to cause a denial of service (crash) via a glob expression with the GLOB_ALTDIRFUNC flag, which triggers     an uninitialized pointer dereference. (CVE-2011-2728)

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

The remote host is affected by the vulnerability described in GLSA-201701-75 (Perl: Multiple vulnerabilities)

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

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, cause a Denial of Service condition, or       escalate privileges.
  Workaround :

    There is no known workaround at this time.
