Description Florian Weimer 2015-09-09 15:03:59 UTC

It was discovered that Apache HttpClient did not apply a configured
connection or read timeout during the initial handshake of an HTTPS
connection.  As a result, HTTPS connection could get stuck, causing
a denial of service if multiple such connections accumulate.

Comment 1 Florian Weimer 2015-09-09 15:06:25 UTC

Upstream patch:

http://svn.apache.org/viewvc/httpcomponents/httpclient/branches/4.3.x/httpclient/src/main/java/org/apache/http/conn/ssl/SSLConnectionSocketFactory.java?r1=1560975&r2=1626784

Originally reported in bug 1259892

Comment 3 Florian Weimer 2015-09-09 15:09:13 UTC

I could not reproduce this issue with HttpClient 4.2.x, mostly due to lack of relevant APIs.  According to the upstream report, it was fixed in version 4.3.6 of the 4.3.x branch.
