Vulnerability Title
Xorg: xwayland: buffer overflow in xkbchangetypesofkey()
来源: CVE Program / CVE List V5
Vulnerability Description
A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey() is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because the key actions are of the wrong size.

Vulnerability Title
X.Org和Xwayland 安全漏洞
来源: 中国国家信息安全漏洞库 CNNVD
Vulnerability Description
X.Org是X.Org基金会的一个开放源代码的自由软件。Xwayland是Xwayland开源的一个通信协议，规定了显示服务器与其客户机之间的通信方式。 X.Org和Xwayland存在安全漏洞，该漏洞源于XkbChangeTypesOfKey函数在组为0时调整键符号表大小为0但未更改键操作，后续调用时可能导致缓冲区溢出。
