CVE-2010-0705 – Avast! 4.7 - 'aavmker4.sys' Local Privilege Escalation

https://notcve.org/view.php?id=CVE-2010-0705

Aavmker4.sys in avast! 4.8 through 4.8.1368.0 and 5.0 before 5.0.418.0 running on Windows 2000 and XP does not properly validate input to IOCTL 0xb2d60030, which allows local users to cause a denial of service (system crash) or execute arbitrary code to gain privileges via IOCTL requests using crafted kernel addresses that trigger memory corruption. Aavmker4.sys en avast! desde v4.8 hasta v4.8.1368.0 y v5.0 anteriores a v5.0.418.0 corriendo sobre Windows 2000 o XP, no valida adecuadamente una entrada a IOCTL 0xb2d60030, lo que permite a usuarios locales producir una denegación de servicio (caída del sistema) o ejecutar código arbitrario para ganar privilegios a través de peticiones IOCTL utilizando direcciones de kernel manipuladas que inician una corrupción de memoria. • https://www.exploit-db.com/exploits/12406 http://forum.avast.com/index.php?topic=55484.0 http://osvdb.org/62510 http://secunia.com/advisories/38677 http://secunia.com/advisories/38689 http://www.securityfocus.com/archive/1/509710/100/0/threaded http://www.securityfocus.com/bid/38363 http://www.securitytracker.com/id?1023644 http://www.trapkit.de/advisories/TKADV2010-003.txt http://www.vupen.com/english/advisories/2010/0449 • CWE-20: Improper Input Validation •
