CVE-2009-3024

Publication date 31 August 2009

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The verify_hostname_of_cert function in the certificate checking feature in IO-Socket-SSL (IO::Socket::SSL) 1.14 through 1.25 only matches the prefix of a hostname when no wildcard is used, which allows remote attackers to bypass the hostname check for a certificate.
