[原文]X Fontserver for Truetype fonts (xfstt) 1.4 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a (1) FS_QueryXExtents8 or (2) FS_QueryXBitmaps8 packet, and possibly other types of packets, with a large num_ranges value, which causes an out-of-bounds array access.


[CNNVD]xfstt远程拒绝服务攻击漏洞(CNNVD-200308-070)

        
        X Fontserver Truetype fonts用于对TrueType字体进行解析。
        xfstt由于不正确处理用户提交的恶意包,远程攻击者可以利用这个漏洞触发缓冲区溢出,进行拒绝服务攻击。
        问题存在于xfstt.cc文件中的working()函数调用中,对来自外部接收到的数据缺少充分边界缓冲区检查,攻击者发送包含超大'req->num_ranges'值的包给xfstt服务器,可导致触发缓冲区溢出,也可能以xfstt进程权限在系统上执行任意指令。

- 漏洞讨论

It has been reported that attackers may be able to crash an xfstt server by sending it a specially malformed packet. Reportedly, the working() function may not properly perform bounds checking on incoming packets prior to parsing headers and storing information in internal buffers. This may allow arbitrary data to be written to adjacent memory locations, possibly resulting in a denial of service condition against the server.

- 漏洞利用

It has been reported that a functional exploit for this vulnerability exists, but is not publicly available. It is also likely that this issue could be exploited with any number of available packet shaping tools.

- 解决方案

Debian has released a security advisory (DSA 360-1) that contains fixes to address this issue. Information relating to obtaining and applying fixes can be found in the referenced advisory.
