Detailsinfo

A vulnerability, which was classified as critical, has been found in cygwin 1.5.7-1. This issue affects some unknown functionality in the library cygwin1.dll of the file scp.exe. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was released 11/29/2007 by Jesus Olmos Gonzalez (Website). The advisory is shared at cygwin.com. The identification of this vulnerability is CVE-2007-6181 since 11/29/2007. The attack may be initiated remotely. A simple authentication is required for exploitation. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 28330 (Cygwin < 1.5.24 cygwin1.dll Crafted Filename Handling Overflow), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (38670), Tenable (28330), SecurityFocus (BID 26557†) and Vulnerability Center (SBV-16983†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
