arbitrary code. (CVE-2018-15518)

It was discovered that Qt incorrectly handled certain GIF images. A remote
attacker could use this issue with a specially crafted GIF image to cause
Qt to crash, resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2018-19870)

It was discovered that Qt incorrectly handled certain BMP images. A remote
attacker could use this issue with a specially crafted BMP image to cause
Qt to crash, resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2018-19873)
