Description

The IO::Socket::SSL module for Perl is prone to a security- bypass vulnerability because the application fails to properly validate certificate hostnames.

Successfully exploiting this issue allows attackers to bypass certain security restrictions, which may aid in further attacks.

Versions prior to IO::Socket::SSL 1.26 are vulnerable.
