Description Jure Repinc 2008-12-06 13:14:32 UTC

Version:            (using Devel)
Compiler:          GCC 4.3.2 AMD64
OS:                Linux
Installed from:    Compiled sources

I'm using Konqueror from SVN (kdelibs r893187, kdebase r893196). Using Firefox I can log into Digg.com just fine, using Konqueror I get an error. I guess it has something to do with JavaScript.

Steps to reproduce:
1. visit http://digg.com/
2. click on Login link at the top

Actual result:
You get an error message saying:
"Resource exhaustion trying to perform regexp match."

Expected:
Instead of the error an overlay should be shown with login form.

Comment 1 Matej Repinc 2008-12-07 20:47:05 UTC

I can confirm that, Konqueror 4.1.82.

Comment 2 wieszti 2009-03-16 00:16:37 UTC

And I confirm that, konqueror 4.2.1 from debian experimental

Comment 3 Maksim Orlovich 2009-05-05 16:41:54 UTC

This means a regexp they use is too crappy for PCRE to handle w/o running out of stack space....

Comment 4 Mike Bridge 2010-01-10 03:21:06 UTC

This still exists in KDE 4.3.4.

Comment 5 Justin Zobel 2021-03-21 00:26:01 UTC

Thank you for the bug report.

As this report hasn't seen any changes in 10 years or more, we ask if you can please confirm that the issue still persists.

If this bug is no longer persisting or relevant please change the status to resolved.

Dear user,

KHTML (and KJS) was a long time more or less unmaintained and got removed in KF6.

Please migrate to use a QWebEngine based HTML component.

We will do no further fixes or improvements to the KF5 branches of these components beside important security fixes.

For security issues, please see:

https://kde.org/info/security/

Sorry that we did not fix this issue during the life-time of KHTML.

Greetings
Christoph Cullmann
