GDB Output and sample request

Hi List,

we're having a problem with the libapreq (libapreq2-2.13). Sometimes HTTP requests are resulting in a segfault of our apache:

[Wed Jan 31 11:51:26 2018] [notice] child pid 7417 exit signal Segmentation faul
t (11)

We've generated a core dump (please see attached gdboutput) and traced it back to
the apreq_hook_find_param function. It looks like the hook pointer sometimes gets 
corrupted and points to itself, resulting in a segfault.

I've also attached the (anonymized) request which results in the segfault.

Please contact me if you need further information.

Thank you and best regards

Please help us to refine our list of open and current defects; this is a mass update of old and inactive Bugzilla reports which reflect user error, already resolved defects, and still-existing defects in httpd.

As repeatedly announced, the Apache HTTP Server Project has discontinued all development and patch review of the 2.2.x series of releases. The final release 2.2.34 was published in July 2017, and no further evaluation of bug reports or security risks will be considered or published for 2.2.x releases. All reports older than 2.4.x have been updated to status RESOLVED/LATER; no further action is expected unless the report still applies to a current version of httpd.

If your report represented a question or confusion about how to use an httpd feature, an unexpected server behavior, problems building or installing httpd, or working with an external component (a third party module, browser etc.) we ask you to start by bringing your question to the User Support and Discussion mailing list, see [https://httpd.apache.org/lists.html#http-users] for details. Include a link to this Bugzilla report for completeness with your question.

If your report was clearly a defect in httpd or a feature request, we ask that you retest using a modern httpd release (2.4.33 or later) released in the past year. If it can be reproduced, please reopen this bug and change the Version field above to the httpd version you have reconfirmed with.

Your help in identifying defects or enhancements still applicable to the current httpd server software release is greatly appreciated.
