Stack-based buffer overflow in Gadu-Gadu 7.20 allows remote attackers to cause a denial of service (crash) via an image filename between exactly 192 to 200 characters, which does not account for the "imgcache\" string that is added to the end of the buffer.

Vulnerability Title
Gadu-Gadu长图形文件名栈缓冲区溢出漏洞
Vulnerability Description
Gadu-Gadu是一款即时消息通讯程序。 GG的图形文件名长度中存在栈溢出。如果图形名称长度处于192到200(含)之间，就可以溢出缓冲区。由于缓冲区的硬写入长度为200字节，因此对文件名做了该限制检查，但之后又连接了"imgcache\"字符串并拷贝到了栈缓冲区，因此可以覆盖9个字节。由于栈受到保护，因此攻击者很难利用这个漏洞执行任意代码，但可以导致拒绝服务。
