Description Jan Lieskovsky 2012-10-24 14:41:46 UTC
A NULL pointer dereference flaw was found in the way HTML implementation of KDE libraries performed processing of HTML pages containing frames with null parts. A remote attacker could provide a specially-crafted web page that, when opened in an application linked against KDE libraries (such as konqueror) would lead to that application crash.

Relevant upstream patch:

Comment 1 Jan Lieskovsky 2012-10-24 14:42:40 UTC
This issue did NOT affect the versions of the kdelibs package, as shipped with Red Hat Enterprise Linux 5 and 6.

Comment 3 Jan Lieskovsky 2012-10-24 15:19:02 UTC

Not a security flaw. Red Hat Security Response Team does not consider a user-assisted end user application crash (such a konqueror) to be a security issue.
