CVE-2010-3877

La función get_Name en net/tipc/socket.c en el kernel de Linux anterior a v2.6.37-rc2 no inicia una determinada estructura, que permite a usuarios locales obtener información sensible de la pila del núcleo de memoria mediante la lectura de una copia de esta estructura.

Multiple vulnerabilities have been discovered and fixed in the Linux 2.6 kernel. The X.25 implementation does not properly parse facilities, which allows remote attackers to cause a denial of service (heap memory corruption and panic) or possibly have unspecified other impact via malformed data, a different vulnerability than CVE-2010-4164. The bcm_connect function Broadcast Manager in the Controller Area Network implementation in the Linux creates a publicly accessible file with a filename containing a kernel memory address, which allows local users to obtain potentially sensitive information about kernel memory use by listing this filename. The install_special_mapping function in mm/mmap.c does not make an expected security_file_mmap function call, which allows local users to bypass intended mmap_min_addr restrictions and possibly conduct NULL pointer dereference attacks via a crafted assembly-language application. Various other issues have also been addressed.
