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

  - 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)

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

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)
