Name of the Vulnerable Software and Affected Versions
X.Org and Xwayland (affected versions not specified)
Description
A buffer overflow flaw was found. The issue arises when the function
XkbChangeTypesOfKey() is called with a 0 group, which resizes the key symbols table to 0 but leaves the key actions unchanged. If the same function is later called with a non-zero value of groups, it causes a buffer overflow because the key actions are of the wrong size.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
