Short explanation
A flaw exists in the GIMP PSD thumbnail loader due to missing validation during the BGR-to-RGB channel swap, leading to heap out-of-bounds read and write [S0].
When a victim browses or opens a crafted file, it can lead to application crashes and potentially arbitrary code execution within the plug-in process [S0].
What should be done?
- Follow vendor advisories and updates [S0].
Chain of evidence and sources
PSD küçük resim yükleyicisi, BGR'den RGB'ye kanal değişimi sırasında JPEG küçük resminin RGB olup olmadığını doğrulamamaktadır [S0].
Hazırlanmış gri tonlamalı PSD küçük resmi, yığın sınırları dışı okuma ve yazmaya neden olur [S0].
Show the technical text from the sources
A flaw was found in GIMP. The PSD thumbnail resource loader performs a BGR-to-RGB channel swap with a fixed 3-byte stride and does not verify that the JPEG thumbnail is RGB. A crafted grayscale PSD thumbnail can cause a heap out-of-bounds read and write in the plug-in process, leading to a crash and potentially arbitrary code execution when the victim browses or opens the file.
