Comment 1 Ted Jongseok Won 2020-10-12 01:09:51 UTC
This vulnerability is out of security support scope for the following product:
 * Red Hat JBoss Enterprise Web Server 2

Please refer to https://access.redhat.com/support/policy/updates/jboss_notes for more details.

Comment 2 Joe Orton 2020-10-12 08:35:08 UTC
It's hard to see from the description, but I'm guessing this is about unsafe temp file creation in e.g.:

https://github.com/apache/httpd/blob/1.3.x/src/support/htpasswd.c#L525

this will not affect any httpd 2.x release, which uses APR's safe temp file creation based off mkstemp().

Comment 5 Huzaifa S. Sidhpurwala 2020-10-14 06:25:08 UTC
Statement:

All versions of httpd package shipped with Red Hat Products, uses APR's safe temp file creation and therefore they are not affected by this flaw
