Description Ratul Gupta 2013-12-31 07:02:45 UTC
A flaw was discovered in the Calligra Sheets of Calligra Suite, where it can be DoS'd via XML entity attack, which can cause the application to consume excessive machine resources and can lead to the crashing of the application.

Test File to reproduce this bug.

This file, when opened in Calligra sheets, leads to hogging of machine resources and ultimately crashes the application.
