CVE-2007-4578

https://notcve.org/view.php?id=CVE-2007-4578

Sophos Anti-Virus for Windows and for Unix/Linux before 2.48.0 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted UPX packed file, resulting from an "integer cast around". NOTE: as of 20070828, the vendor says this is a DoS and the researcher says this allows code execution, but the researcher is reliable. Sophos Anti-Virus para Windows y para Unix/Linux anterior a 2.48.0 permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código de su elección mediante un archivo empaquetado con UPX manipulado, resultado de una "conversión de vuelta de entero" (integer cast around). NOTA: a fecha de 28/08/2007, el fabricante dice que esto es una denegación de servicio y el investigador dice que permite ejecución de código, pero el investigador es fiable. • http://secunia.com/advisories/26580 http://securityreason.com/securityalert/3072 http://securitytracker.com/id?1018608 http://www.nruns.com/security_advisory_sophos_upx_infinite_loop_dos.php http://www.securityfocus.com/archive/1/477720/100/0/threaded http://www.securityfocus.com/archive/1/477864/100/0/threaded http://www.securityfocus.com/archive/1/477882/100/0/threaded http://www.securityfocus.com/bid/25428 http://www.sophos.com/support/knowledgebase/article/28407.html http:/& • CWE-189: Numeric Errors •
