Description Vasyl Kaigorodov 2015-01-13 15:42:58 UTC

It was reported [1] that mod_remoteip does not properly filter the IP addresses supplied in HTTP headers, which can allow a remote attacker to hide his real IP address, or bypass IP based restrictions.
This issue is fixed upstream:
https://svn.apache.org/viewvc?view=revision&revision=1564052

Comment 1 Vasyl Kaigorodov 2015-01-13 15:43:25 UTC

Created httpd tracking bugs for this issue:

Affects: fedora-all [bug 1181699]

Comment 3 Tomas Hoger 2015-03-17 12:28:26 UTC

The affected mod_remoteip module was introduced upstream in version 2.4:

http://httpd.apache.org/docs/2.4/new_features_2_4.html#newmods

Therefore, this issue did not affect httpd versions as shipped in Red Hat Enterprise Linux 6 and earlier, which include httpd 2.2 or earlier.

Issue was corrected upstream in version 2.4.8:

https://svn.apache.org/viewvc?view=revision&revision=1569006
