Vulnerability Description
Heap-based buffer overflow in cygwin1.dll in Cygwin 1.5.7 and earlier allows context-dependent attackers to execute arbitrary code via a filename with a certain length, as demonstrated by a remote authenticated user who uses the SCP protocol to send a file to the Cygwin machine, and thereby causes scp.exe on this machine to execute, and then overwrite heap memory with characters from the filename. NOTE: it is also reported that a related issue might exist in 1.5.7 through 1.5.19.

Cygwin超长文件名堆溢出漏洞
Vulnerability Description
Cygwin是许多自由软件的集合，用于在各种版本的Microsoft Windows上运行UNIX类系统。 Cygwin处理超长文件名时存在漏洞，恶意用户可能利用此漏洞在系统上执行任意指令。 一般来讲Linux文件系统允许255字节的文件名，但cygwin允许239字节，并执行检查防范大于等于240字节的文件名。尽管执行了这个检查，存储文件名的动态内存缓冲区仅分配了232字节，因此233到239字节的文件名可以绕过检查覆盖堆上最多7个字节，导致执行任意指令。
