Background
libwmf is a library that allows applications to read and write Windows Metafile Format (WMF) files. It provides functionality for parsing and rendering WMF files. The library is commonly used in applications that handle graphics and images. However, a flaw has been discovered in libwmf's WMF parser, which can lead to excessive memory allocation and potential crashes.
Vulnerability Detail
