Vulnerability Title
Gimp: gimp: application crash (dos) via crafted psd file due to heap-buffer-overflow
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in GIMP. Heap-buffer-overflow vulnerability exists in the fread_pascal_string function when processing a specially crafted PSD (Photoshop Document) file. This occurs because the buffer allocated for a Pascal string is not properly null-terminated, leading to an out-of-bounds read when strlen() is subsequently called. Successfully exploiting this vulnerability can cause the application to crash, resulting in an application level Denial of Service.
