RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

+++ This bug was initially created as a clone of Bug #636427 +++

Description of problem:
A bug has been found in mod_ssl where it uses memcpy in place of
memmove, which can cause random memory corruption.  Whilst this
has not been seen in RHEL-6 as yet, future changes to the glibc memcpy 
implementation may trigger this and break mod_ssl; it would be
prudent to fix this in the RHEL-6 httpd.  Some change to the 
Fedora/upstream glibc memcpy implementation (or possibly the gcc
inline memcpy) has been triggering new reports of this recently.

This is a low-risk change; fix tested succesfully in Fedora and upstream.

Version-Release number of selected component (if applicable):
httpd-2.2.15-5.el6

How reproducible:
currently not known to be, in RHEL6

I think this bug is the cause for lots of random errors when using https:

Your browser sent a request that this server could not understand
Request header field is missing ':' separator.

These errors happens with an SSL-enabled httpd in front of several tomcat5.5, tomcat6 and jboss servers (mod_jk used). With plain httpd, no errors appear on any application.
