CVE-2019-20326

HIGH
New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

A heap-based buffer overflow in _cairo_image_surface_create_from_jpeg() in extensions/cairo_io/cairo-image-surface-jpeg.c in GNOME gThumb before 3.8.3 and Linux Mint Pix before 2.4.5 allows attackers to cause a crash and potentially execute arbitrary code via a crafted JPEG file.
