Description
A flaw was found in LibreOffice. When importing a specially crafted PICT image embedded in a document, an out-of-bounds read vulnerability exists. This occurs because the palette index in the image data is not validated against the actual size of the color palette. A remote attacker could exploit this to read memory outside the intended buffer, potentially leading to information disclosure or a denial of service.
