This can be exploited to cause a stack-based buffer overflow and allows arbitrary code execution when a specially crafted archive is extracted. The vulnerability has been confirmed in the following products. * ZipStar 5.0 Build 4285 * Squeez 5.0 Build 4285 * SpeedCommander 11.0 Build 4430 * SpeedCommander 10.51 Build 4430 2) A boundary error exists in CxUux60.dll and CxUux60u.dll due to the unsafe use of the "lstrcpy()" function when constructing the full pathname of the file that is decoded from a UUE file. This can be exploited to cause a stack-based buffer overflow and allows arbitrary code execution when a specially crafted UUE file is decoded. The vulnerability has been confirmed in the following products. * Squeez 5.0 Build 4285 * SpeedCommander 11.0 Build 4430 * SpeedCommander 10.51 Build 4430 ====================================================================== 4) Solution Update to the fixed versions.
