Descriptions

The virSecurityManagerGetPrivateData function in security/security_manager.c in libvirt 0.8.8 through 0.9.1 uses the wrong argument for a sizeof call, which causes incorrect processing of "security manager private data" that "reopens disk probing" and might allow guest OS users to read arbitrary files on the host OS. NOTE: this vulnerability exists because of a CVE-2010-2238 regression.

La función virSecurityManagerGetPrivateData de security/security_manager.c en libvirt 0.8.8 hasta la 0.9.1 utiliza un argumento erróneo para una llamada "sizeof", lo que provoca un procesado incorrecto de "datos privados de gestión de la seguridad" que reabre un análisis de disco y pueden permitir a usuarios invitados del SO leer archivos arbitarrios en del OS anfitrión. NOTA: esta vulnerabilidad existe debido a una regresión de la CVE-2010-2238.
