Description Filip Kobierski 2024-09-04 07:42:24 UTC 
Via a maliciously crafted pandore or bmp file with modified dx and dy header field values it is possible to trick the application into allocating huge buffer sizes like 64 Gigabyte upon reading the file from disk or from a virtual buffer.

I have created a PR fixing this:

Based on the referenced pull request upstream this is fixed in 3.4.2.
Comment 2 Hans de Graaff gentoo-dev Security 2024-09-08 08:26:21 UTC 
Adjusting whiteboard status given that there are no stable versions of this package.
