Name of the Vulnerable Software and Affected Versions
Net::CIDR::Set versions prior to 0.21
Description
Net::CIDR::Set for Perl fails to properly validate network masks. The mask portion may contain non-digits or Unicode digits, such as the Arabic-Indic One (U+0661), which are ignored, potentially allowing the acceptance of larger networks. Additionally, leading zeros are treated as decimal values rather than octal, which can cause ambiguity regarding acceptable networks.
Recommendations
Update to a version later than 0.20.
