An issue was discovered in Avast antivirus before 19.8 and AVG antivirus before 19.8. A DLL Preloading vulnerability allows an attacker to implant %WINDIR%\system32\wbemcomn.dll, which is loaded into a protected-light process (PPL) and might bypass some of the self-defense mechanisms. This affects all components that use WMI, e.g., AVGSvc.exe 19.6.4546.0 and TuneupSmartScan.dll 19.1.884.0. Se detectó un problema en Avast antivirus versiones anteriores a 19.8 y AVG antivirus versiones anteriores a 19.8. Una vulnerabilidad de Precarga de DLL permite a un atacante implantar una biblioteca %WINDIR%\system32\wbemcomn.dll, que se carga en un proceso protected-light (PPL) y puede omitir algunos de los mecanismos de autodefensa. • https://safebreach.com/Post/Avast-Antivirus-AVG-Antivirus-DLL-Preloading-into-PPL-and-Potential-Abuses https://safebreach.com/blog • CWE-427: Uncontrolled Search Path Element •

In Avast Antivirus before 19.4, a local administrator can trick the product into renaming arbitrary files by replacing the Logs\Update.log file with a symlink. The next time the product attempts to write to the log file, the target of the symlink is renamed. This defect can be exploited to rename a critical product file (e.g., AvastSvc.exe), causing the product to fail to start on the next system restart. En Avast Antivirus antes de 19.4, un administrador local puede engañar al producto para que cambie el nombre de los archivos arbitrarios al reemplazar el archivo Logs \ Update.log con un enlace simbólico. La próxima vez que el producto intente escribir en el archivo de registro, se cambiará el nombre del destino del enlace simbólico. • http://www.mcerlane.co.uk/CVE-2019-11230 http://www.securityfocus.com/bid/109344 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

Comodo Antivirus versions 11.0.0.6582 and below are vulnerable to Denial of Service affecting CmdGuard.sys via its filter port "cmdServicePort". A low privileged process can crash CmdVirth.exe to decrease the port's connection count followed by process hollowing a CmdVirth.exe instance with malicious code to obtain a handle to "cmdServicePort". Once this occurs, a specially crafted message can be sent to "cmdServicePort" using "FilterSendMessage" API. This can trigger an out-of-bounds write if lpOutBuffer parameter in FilterSendMessage API is near the end of specified buffer bounds. The crash occurs when the driver performs a memset operation which uses a size beyond the size of buffer specified, causing kernel crash. • https://www.tenable.com/security/research/tra-2019-34 • CWE-787: Out-of-bounds Write •

Comodo Antivirus versions 12.0.0.6810 and below are vulnerable to Denial of Service affecting CmdAgent.exe via an unprotected section object "<GUID>_CisSharedMemBuff". This section object is exposed by CmdAgent and contains a SharedMemoryDictionary object, which allows a low privileged process to modify the object data causing CmdAgent.exe to crash. Comodo Antivirus versiones 12.0.0.6810 y anteriores, son vulnerables a una Denegación de Servicio que afecta al archivo CmdAgent.exe por medio de un objeto de sección desprotegida de "(GUID)_CisSharedMemBuff". Este objeto de sección está expuesto mediante CmdAgent y contiene un objeto SharedMemoryDictionary, que permite que un proceso poco privilegiado modifique los datos del objeto que causan que el archivo CmdAgent.exe se bloquee. • https://www.tenable.com/security/research/tra-2019-34 • CWE-125: Out-of-bounds Read •
