Jakarta Commons HTTPClient implements the client side of HTTP standards.
It was discovered that the HTTPClient incorrectly extracted host name from
an X.509 certificate subject’s Common Name (CN) field. A man-in-the-middle
attacker could use this flaw to spoof an SSL server using a specially
crafted X.509 certificate. (CVE-2014-3577)
For additional information on this flaw, refer to the Knowledgebase
article in the References section.
All jakarta-commons-httpclient users are advised to upgrade to these
updated packages, which contain a backported patch to correct this issue.
