Fedora 32 : perl-Net-Netmask (2021-c314017fcc)

high Nessus Plugin ID 148789

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 32 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2021-c314017fcc advisory.

 - The Net::Netmask module before 2.0000 for Perl does not properly consider extraneous zero characters at the beginning of an IP address string, which (in some situations) allows attackers to bypass access control that is based on IP addresses. (CVE-2021-29424)

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

Solution

Update the affected perl-Net-Netmask package.
