Attackers can supply a crafted BMP or ICO file with large dimensions so row decoding writes file-derived data past the heap buffer, corrupting the application heap.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-190"],"vendors":[],"products":[],"references":[{"url":"https://github.com/fltk/fltk","tags":[]},{"url":"https://github.com/fltk/fltk/blob/release-1.4.5/src/Fl_BMP_Image.cxx#L281-L286","tags":[]},{"url":"https://github.com/fltk/fltk/commit/3a049d8262dc759cf9737339420e8457e24c0cb1","tags":[]},{"url":"https://github.com/fltk/fltk/issues/1632","tags":[]},{"url":"https://hackmd.io/@haindpwn/fltk-bmp-image-stack-heap-overflow","tags":[]},{"url":"https://www.vulncheck.com/advisories/fltk-through-1.4.5-heap-buffer-overflow-via-fl-bmp-image-integer-overflow","tags":[]}],"exploitRefs":[{"url":"https://github.com/fltk/fltk","tags":[]},{"url":"https://github.com/fltk/fltk/blob/release-1.4.5/src/Fl_BMP_Image.cxx#L281-L286","tags":[]},{"url":"https://github.com/fltk/fltk/commit/3a049d8262dc759cf9737339420e8457e24c0cb1","tags":[]},{"url":"https://github.com/fltk/fltk/issues/1632","tags":[]}],"hasPoc":true,"ai":null}
