Description Joe Orton 2010-09-22 08:36:15 UTC
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-5 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-5 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 relatively low-risk change; fix tested succesfully in 
Fedora.

Version-Release number of selected component (if applicable):
httpd-2.2.3-43.el5_5.3

How reproducible:
currently not known to be, in RHEL5

Comment 1 Joe Orton 2010-09-22 08:38:55 UTC
For reference, Fedora bug 634905.

Comment 2 RHEL Program Management 2010-09-22 08:46:55 UTC
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.
