CVE-2021-28308
CVSS v3.1
9.1
Critical
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
fltk crate versions prior to 0.15.3
Description:
The issue is related to multiple memory safety problems. There is an out-of-bounds read due to the lack of input validation in the pixmap constructor. Additionally, NULL pointer dereferences can occur when attempting to use a non-raster image for a window icon or when setting a multi-label type with a nonexistent image.
Recommendations:
For versions prior to 0.15.3, update to version 0.15.3 or later to resolve the issue. As a temporary workaround, consider avoiding the use of non-raster images for window icons and ensuring that images exist before setting multi-label types. Restrict the use of the pixmap constructor until a patch is available.
Fix
Out of bounds Read
NULL Pointer Dereference
