  script_tag(name:"insight", value:"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 [link moved to references]

For Debian 8 Jessie, this problem has been fixed in version 3:3.3.1-2.1+deb8u1

We recommend that you upgrade your gthumb packages.
