Description


Nth Dimension has reported multiple vulnerabilities in KDE, which can be exploited by malicious people to compromise a user's system.

1) An error in kdelibs (khtml/css/cssparser.cpp) when parsing the source for font faces in Cascading Style Sheets (CSS) can be exploited to cause a heap-based buffer overflow.

2) An error in kdelibs (khtml/imload/scaledimageplane.h) when calculating canvas dimensions can be exploited to cause a heap-based buffer overflow.

3) A use-after-free error exists in kdelibs (khtml/rendering/render_replaced.cpp ) during widget rendering for context menus of an iframe.

Successful exploitation of the vulnerabilities may allow execution of arbitrary code.


Solution:
Fixed in the source code repository.
