CVE-2013-1827

net/dccp/ccid.h en el kernel de Linux anterior a v3.5.4 permite a usuarios locales obtener privilegios o causar una denegación de servicio (referencia a puntero NULL y caída del sistema) mediante el aprovechamiento de la capacidad CAP_NET_ADMIN para cierto (1) remitente o (2) llamada getsockopt.

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6. An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way the Intel i915 driver in the Linux kernel handled the allocation of the buffer used for relocation copies. A local user with console access could use this flaw to cause a denial of service or escalate their privileges. A buffer overflow flaw was found in the way UTF-8 characters were converted to UTF-16 in the utf8s_to_utf16s() function of the Linux kernel's FAT file system implementation. A local user able to mount a FAT file system with the "utf8=1" option could use this flaw to crash the system or, potentially, to escalate their privileges.
