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. (CVE-2012-5783)
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.
