The "as used in" part of the description is not correct.  The confusion is probably caused by upstream using CVE-2010-1623 CVE id in commits fixing apr_brigade_split_line() issue in apr-util as well as similar flaw in the mod_reqtimeout module.  mod_reqtimeout was not using apr_brigade_split_line().

mod_reqtimeout module was introduced in httpd version 2.2.15:
http://svn.apache.org/viewvc/httpd/httpd/branches/2.2.x/CHANGES?revision=917876&view=markup#l26

Vulnerable code was never part of released 2.2.x version, the issue only affected development versions:
http://svn.apache.org/viewvc?view=revision&revision=1005957

that corrects previous commit:
http://svn.apache.org/viewvc?view=revision&revision=1005669
