X.Org DoS, Code Execution Vulns Fixed
Several significant out-of-bounds access vulnerabilities have been found in the X.Org X Server (CVE-2021-4008, CVE-2021-4009, and CVE-2021-4011). These flaws threaten data confidentiality and integrity, as well as system availability, and have received a National Vulnerability Database severity rating of “High”.
An attacker could exploit these bugs to cause the server to crash, resulting in a denial of service (DoS), or possibly execute arbitrary code and escalate privileges.
An update is available for X.Org that fixes these issues. We urge all impacted users to apply the updates issued by their distro(s) as soon as possible to protect their sensitive data and ensure their crucial systems remain accessible.
