Vulnerability Assessment Details

[GLSA-200408-20] Qt: Image loader overflows

Vulnerability Assessment Summary
Qt: Image loader overflows

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200408-20
(Qt: Image loader overflows)


There are several unspecified bugs in the QImage class which may cause
crashes or permit execution of arbitrary code as the user running the Qt
application. These bugs affect the PNG, XPM, BMP, GIF and JPEG image types.

Impact

A possible hacker may exploit these bugs by causing a user to open a
carefully-constructed image file in any one of these formats. This may be
accomplished through e-mail attachments (if the user uses KMail), or by
simply placing a malformed image on a website and then convicing the user
to load the site in a Qt-based browser (such as Konqueror).

Workaround

There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of Qt.
