Descriptions
LibVNC commit before d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a contains a memory leak (CWE-655) in VNC server code, which allow an attacker to read stack memory and can be abused for information disclosure. Combined with another vulnerability, it can be used to leak stack memory and bypass ASLR. This attack appear to be exploitable via network connectivity. These vulnerabilities have been fixed in commit d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a.
LibVNC en el commit anterior a d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a, contiene una pérdida de memoria (CWE-655) en el código del servidor VNC, lo que permite a un atacante leer la memoria de la pila y puede ser abusada para la divulgación de información. Combinada con otra vulnerabilidad, puede ser usada para filtrar la memoria de la pila y omitir el ASLR. Este ataque parece ser explotable por medio de la conectividad de la red. Estas vulnerabilidades han sido corregidas en el commit d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a.
