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

Description The issue is related to a flaw in the input validation mechanism of the qsvghandler.cpp component in the Qt cross-platform framework. This flaw can be exploited by a remote attacker using a malformed SVG image, potentially leading to a denial of service due to a segmentation fault in qsvghandler.cpp.

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 use of SVG images from untrusted sources to minimize the risk of exploitation.
