Описание
A flaw was found in the X.Org X server's XKB key types request validation. A local attacker could send a specially crafted request to the X server, leading to an out-of-bounds memory access vulnerability. This could result in the disclosure of sensitive information or cause the server to crash, leading to a Denial of Service (DoS). In certain configurations, higher impact outcomes may be possible.
Отчет
An Important out-of-bounds memory access vulnerability exists in the X.Org X server's XKB key types request validation. This flaw could lead to information exposure or a server crash and requires a specially crafted request to trigger. Systems running a graphical environment are potentially affected, with higher impact outcomes possible in certain configurations.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
