7.8
High
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
X.Org (affected versions not specified)
Description
A security flaw was found in X.Org due to the XkbCopyNames function leaving a dangling pointer to freed memory. This results in out-of-bounds memory access on subsequent XkbGetKbdByName requests, potentially leading to local privilege elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions. The issue can also allow an attacker to access confidential data, compromise its integrity, and cause a denial of service.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
