Descriptions
A flaw was found in the RandR extension, where the RRChangeProviderProperty function does not properly validate input. This issue leads to an integer overflow when computing the total size to allocate.
USN-7573-1 fixed several vulnerabilities in X.Org. This update provides the corresponding update for Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. Nils Emmerich discovered that the X.Org X Server incorrectly handled certain memory operations. An attacker could use these issues to cause the X Server to crash, leading to a denial of service, obtain sensitive information, or possibly execute arbitrary code.
