The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) associated with each description below.
The Jakarta Commons HttpClient component can be used to build HTTP-aware client applications (such as web browsers and web service clients).
The Jakarta Commons HttpClient component did not verify that the server hostname matched the domain name in the subject's Common Name (CN) or subjectAltName field in X.509 certificates. This could allow a man-in-the-middle attacker to spoof an SSL server if they had a certificate that was valid for any domain name.
All users of jakarta-commons-httpclient are advised to upgrade to these updated packages, which correct this issue. Applications using the Jakarta Commons HttpClient component must be restarted for this update to take effect.
