> elogd binary from EPEL

thank you for bringing this up to our attention. we recently went through this with debian and ubuntu. the elog package was severely out of date and 
did not include the security patches that went it right before covid started in the Winter of 2020.

the elogd package in EPEL7 is insecure and should not be used. (I see it is removed from EPEL8, EPEL9 and current Fedora).

I will have to contact EPEL maintainers to have it removed from EPEL7 (or at least to have it marked as "insecure, do not use").

Good day, elog has never been retired in EPEL 7. It is still there
https://src.fedoraproject.org/rpms/elog/tree/epel7

I am pretty sure because I am a Fedora/RHEL package maintainer and a retired package should contain in its Git branch only a file named "dead.package"

Hello, the following URL

Dear Stefan, 

There is a problem with editing an Elog page in "plain" format with the following "User Agent" :

"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/16.1 Safari/605.1.15"

It duplicates the newline symbols such that "1<CRLF>2" becomes "1<CRLF><CRLF>2". If edited again - "1<CRLF><CRLF><CRLF><CRLF>2".

I blame the new version of the Apple WebKit. 

It works fine with Chrome (user agent: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36"). But fails with Safari. 
 

Could you please have a look? 

Thank you in advance, 

Andrey Pashnin

It shound't be a "bug report", sorry. I have changed the category to "Info".

It seems to be really a bug in the WebKit core. I have created a bug report there. For reference: https://bugs.webkit.org/show_bug.cgi?id=249923

I am going to try to patch the ELOG code to handle the content of the textarea in the "plain" format.... it doesn't seem possible though. 

FYI.

Removing "wrap=hard" on the line #11461 in the elogd.cxx file resolves my problem.

- rsprintf("<textarea rows=%d cols=%d wrap=hard name=\"Text\">\n", height, width);*/
+ rsprintf("<textarea rows=%d cols=%d name=\"Text\">\n", height, width);

- rsprintf("<textarea rows=%d cols=%d wrap=hard name=\"Text\">\n", height, width);
+ rsprintf("<textarea rows=%d cols=%d name=\"Text\">\n", height, width);

my vote is to remove "wrap=hard":

1) I try to read the specs and my head explodes: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/textarea
2) textarea should just accept input typed by user, should not try to "neatify" it. if user wants long lines, we should let them.
3) this bug (introduced in recent safari, the best I can tell)

K.O.

FYI

They seem to have accepted the bug report:
