CVE-2020-26208

Estado: ModificadaMedia (6.1)—

JHEAD is a simple command line tool for displaying and some manipulation of EXIF header data embedded in Jpeg images from digital cameras. In affected versions there is a heap-buffer-overflow on jhead-3.04/jpgfile.c:285 ReadJpegSections. Crafted jpeg images can be provided to the user resulting in a program crash or potentially incorrect exif information retrieval. Users are advised to upgrade. There is no known workaround for this issue.
