Doc Text:	A memory corruption flaw was found in the way Qt handled certain Icon (ICO) files. If a user loaded a specially crafted ICO image file with an application linked against Qt, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application.

Comment 3 Fedora Update System 2015-04-21 19:11:38 UTC

qt5-qtbase-5.4.1-9.fc22 has been pushed to the Fedora 22 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 4 Kevin Kofler 2015-04-21 23:37:06 UTC

To the best of my knowledge, Qt 3 is NOT vulnerable to this issue, because it does not include an ICO reader. (ICO reading in Qt 3 was provided only in kdelibs3's kimgio, which uses completely different code.)

Qt 4 and Qt 5 are vulnerable, and Fedora updates correcting this vulnerability have been issued.
