Vulnerability Description
The swap_char2b function in X.Org X Font Server (xfs) before 1.0.5 allows context-dependent attackers to execute arbitrary code via (1) QueryXBitmaps and (2) QueryXExtents protocol requests with crafted size values that specify an arbitrary number of bytes to be swapped on the heap, which triggers heap corruption.

X.Org X字体服务器 swap_char2b()函数内存破坏漏洞
Vulnerability Description
X字体服务器(XFS)用于为X窗口系统渲染字体。 此外，QueryXBitmaps和QueryXExtents协议请求处理器中还存在堆破坏漏洞。这两个请求都会导致调用swap_char2b()函数，该函数从请求中获得一个32位的整数，并将其用作在请求缓冲区中所要交换的字节数，这允许攻击者交换堆上的任意数目的字节。
