The parse() method in the Email::Address module through 1.909 for Perl is vulnerable to Algorithmic complexity on specially prepared input, leading to Denial of Service. Prepared special input that caused this problem contained 30 form-field characters ("\f").

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - perl-Email-Address: denial of service when parsing crafted email address list (CVE-2015-7686)

  - perl-Email-Address: Specially crafted input could cause Denial of Service due to complex parse() method     (CVE-2018-12558)

  - The parse function in Email::Address module before 1.905 for Perl uses an inefficient regular expression,     which allows remote attackers to cause a denial of service (CPU consumption) via an empty quoted string in     an RFC 2822 address. (CVE-2014-0477)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

According to the versions of the perl-Email-Address package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Algorithmic complexity vulnerability in Address.pm in     the Email-Address module 1.908 and earlier for Perl     allows remote attackers to cause a denial of service     (CPU consumption) via a crafted string containing a     list of e-mail addresses in conjunction with     parenthesis characters that can be associated with     nested comments. NOTE: the default configuration in     1.908 mitigates this vulnerability but misparses     certain realistic comments.(CVE-2015-7686)

  - The parse() method in the Email::Address module through     1.909 for Perl is vulnerable to Algorithmic complexity     on specially prepared input, leading to Denial of     Service. Prepared special input that caused this     problem contained 30 form-field characters     ('\f').(CVE-2018-12558)
