What is CVE-2018-18718?

A double-free vulnerability has been identified in the gThumb image viewer, where the add_themes_from_dir method in dlg-contact-sheet.c improperly manages memory. This flaw arises from two consecutive calls to g_free, resulting in the deallocation of the same buffer. Such vulnerabilities can potentially lead to application crashes or execute arbitrary code, posing a significant security risk. It is essential for users and administrators to apply updates or patches to safeguard their systems.
