Subject: [PATCH] app: fix #8120 GIMP 2.10.30 crashed when allocate large
|
|
memory
|
|
|
|
GIMP could crash if the information regarding old path properties read
|
|
from XCF was incorrect. It did not check if xcf_old_path succeeded and
|
|
kept trying to load more paths even if the last one failed to load.
|
|
|
|
Instead we now stop loading paths as soon as that function fails.
|
|
In case we have a failure here we also try to skip to the next property
|
|
based on the size of the path property, in hopes that the only problem
|
|
was this property.
