|Description||http/conn/ssl/SSLConnectionSocketFactory.java in Apache HttpComponents HttpClient before 4.3.6 ignores the http.socket.timeout configuration setting during an SSL handshake, which allows remote attackers to cause a denial of service (HTTPS call hang) via unspecified vectors.|

Vulnerable and fixed packages
The table below lists information on source packages.
|bookworm, sid, bullseye||3.1-16||fixed|
|httpcomponents-client (PTS)||buster, buster (security)||4.5.7-1+deb10u1||fixed|
The information below is based on the following data on fixed versions.
[jessie] - httpcomponents-client <no-dsa> (Minor issue)
[squeeze] - httpcomponents-client <not-affected> (Regression introduced in 4.3.0)
[wheezy] - httpcomponents-client <not-affected> (Regression introduced in 4.3.0)
https://issues.apache.org/jira/browse/HTTPCLIENT-1478 says it's really fixed in 4.3.6 and that 4.2.x did not have this bug.
Proposed patch for commons-httpclient: https://bugzilla.redhat.com/show_bug.cgi?id=1259892
Checked that both 4.0.1 (in Squeeze) and 4.1.1 (in Wheezy) have the call to set the timout before the SSL connection is opened.
Jessie's 4.3.5-2 is however missing the 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
