Red Hat Product Errata RHSA-2007:0252 0 normal SHIPPED_LIVE Low: sendmail security and bug fix update 2007-05-01 17:11:07 UTC

Description Michael Redinger 2004-04-28 17:09:00 UTC
version:
sendmail-8.12.10-1

There is a bug in sendmail that makes it enter an infinite loop,
writing
STARTTLS: read error=generic SSL error
to syslog until your filesystem is full ...

For a detailed description, please see:
http://www.mailarchive.ca/lists/comp.mail.sendmail//2003-02/0293.html

To fix this, simply add -D _FFR_DEAL_WITH_ERROR_SSL to
sendmail-8.12.2-redhat.patch . The result looks like this:

+define(`confENVDEF', `$(RPM_OPT_FLAGS) -I/usr/include/db4
-I/usr/kerberos/include -Wall -DXDEBUG=0 -DTCPWRAPPERS -DSASL=2
-DSTARTTLS -DMILTER -DNETINET6 -DHES_GETMAILHOST
-DUSE_VENDOR_CF_PATH=1 -D_FFR_WORKAROUND_BROKEN_NAMESERVERS
-D_FFR_SMTP_SSL -D_FFR_MILTER_ROOT_UNSAFE -D_FFR_UNSAFE_SASL
-D_FFR_DEAL_WITH_ERROR_SSL')


Greetings,
Michael

Comment 1 Thomas Woerner 2004-06-15 14:56:11 UTC
Can you please test this with the latest update for RHEL3?

Comment 2 Ken Snider 2004-07-13 15:07:22 UTC
I haven't yet figured out how to reproduce this bug, but I *do* see it
on several servers. I'm trying to see if upgrading the the U2 sendmail
RPM corrects the issue.

Comment 3 Ken A. 2005-10-24 20:12:42 UTC
seeing it here too... millions of lines of 
Oct 24 10:54:04 mail sendmail[6797]: STARTTLS: read error=generic SSL error (0)
Oct 24 10:54:04 mail sendmail[519]: STARTTLS: read error=generic SSL error (0)
...until the /var/ partition fills up.
on FC3 - sendmail 8.13.1
Please release a fix for FC3!


Comment 4 Michael Redinger 2006-03-09 11:03:23 UTC
This bug still exists in RHEL 4.

To fix it, add _FFR_DEAL_WITH_ERROR_SSL to confENVDEF in the spec file (there is
no need to change/add a patch, as describe above ...).

The bug is still present because Red Hat uses 8.13.1. Since 8.13.3,
_FFR_DEAL_WITH_ERROR_SSL is defined per default.
