CVE-2021-45930
Description
A flaw was found in qtsvg's qsvghandler.cpp module. An attacker who is able to submit a crafted image file to an application that uses qsvghandler could cause an out-of-bounds write and potential denial of service to occur, depending on the application.
Statement
This flaw is out of support scope for versions of qt shipped with Red Hat Enterprise Linux 6 and 7 as it does not affect qt3, which does not have the qsvghandler.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
