Description:
Chris Evans has reported a vulnerability in the Qt library, which potentially can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to boundary errors in the "read_dib()" function when handling 8-bit RLE encoded BMP files. This can be exploited by using an overly long length mark in order to cause a heap-based buffer overflow.
Successful exploitation may allow execution of arbitrary code and can be exploited via any application using the Qt library to display or decode BMP files.
NOTE: Some NULL pointer dereference errors within the handlers for XPM, GIF, and JPEG images can also be exploited to cause a DoS (Denial of Service).
The vulnerability affects version 3.3.2 and prior.
