Package : gthumb Version : 3:3.3.1-2.1+deb8u1 CVE ID : CVE-2018-18718 Debian Bug : #912290
CVE-2018-18718 - CWE-415: Double Free The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
There is a suspected double-free bug with static void add_themes_from_dir() dlg-contact-sheet.c. This method involves two successive calls of g_free(buffer) (line 354 and 373), and is likely to cause double-free of the buffer. One possible fix could be directly assigning the buffer to NULL after the first call of g_free(buffer). Thanks Tianjun Wu https://gitlab.gnome.org/GNOME/gthumb/issues/18
For Debian 8 "Jessie", this problem has been fixed in version 3:3.3.1-2.1+deb8u1
