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 •
CVE-2009-4049 – Avast! AntiVirus 4.8.1356 - 'aswRdr.sys' Driver Privilege Escalation
https://notcve.org/view.php?id=CVE-2009-4049
Heap-based buffer overflow in aswRdr.sys (aka the TDI RDR driver) in avast! Home and Professional 4.8.1356.0 allows local users to cause a denial of service (memory corruption) or possibly gain privileges via crafted arguments to IOCTL 0x80002024. Desbordamiento de búfer basado en memoria dinámica (heap) en aswRdr.sys (también conocido como el controlador TDI RDR) en avast! Home y Professional v4.8.1356.0, permite a usuarios locales provocar una denegación de servicio (corrupción de memoria) o posiblemente elevar sus privilegios a través de argumentos manipulados a IOCTL 0x80002024. • https://www.exploit-db.com/exploits/33360 https://github.com/fengjixuchui/CVE-2009-4049 http://secunia.com/advisories/37368 http://www.efblog.net/2009/11/avast-aswrdrsys-kernel-pool-corruption.html http://www.securityfocus.com/archive/1/507891/100/0/threaded http://www.securityfocus.com/bid/37031 http://www.vupen.com/english/advisories/2009/3266 https://www.evilfingers.com/advisory/Advisory/Avast_aswRdr_sys_Kernel_Pool_Corruption_and_Local_Privilege_Escalation.php • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
