CVE-2018-19870

Name of the Vulnerable Software and Affected Versions Qt versions prior to 5.11.3

Description The issue is related to a NULL pointer dereference in the QGifHandler function when processing a malformed GIF image, resulting in a segmentation fault. This can be exploited by a remote attacker to cause a denial of service using a specially crafted GIF image.

Recommendations For Qt versions prior to 5.11.3, update to version 5.11.3 or later to resolve the issue. As a temporary workaround, consider restricting the handling of GIF images by the QGifHandler function until a patch is available.
