CVSS: 6.9EPSS: 0%CPEs: 11EXPL: 3CVE-2014-4699 – Linux Kernel < 3.2.0-23 (Ubuntu 12.04 x64) - 'ptrace/sysret' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2014-4699
The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls. El kernel de Linux anterior a 3.15.4 en los procesadores Intel no restringe debidamente el uso de un valor no canónico para la dirección RIP guardada en el caso de una llamada del sistema que no utilice IRET, lo que permite a usuarios locales aprovechar una condición de carrera y ganar privilegios, o causar una denegación de servicio (fallo doble), a través de una aplicación manipulada que realice llamadas de sistemas ptrace y fork. It was found that the Linux kernel's ptrace subsystem allowed a traced process' instruction pointer to be set to a non-canonical memory address without forcing the non-sysret code path when returning to user space. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. Note: The CVE-2014-4699 issue only affected systems using an Intel CPU. • https://www.exploit-db.com/exploits/34134 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=b9cd18de4db3c9ffa7e17b0dc0ca99ed5aa4d43a http://linux.oracle.com/errata/ELSA-2014-0924.html http://linux.oracle.com/errata/ELSA-2014-3047.html http://linux.oracle.com/errata/ELSA-2014-3048.html http://openwall.com/lists/oss-security/2014/07/05/4 http://openwall.com/lists/oss-security/2014/07/08/16 http://openwall.com/lists/oss-security/2014/07/08 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-642: External Control of Critical State Data •

https://notcve.org/view.php?id=CVE-2014-4655
The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not properly maintain the user_ctl_count value, which allows local users to cause a denial of service (integer overflow and limit bypass) by leveraging /dev/snd/controlCX access for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls. La función snd_ctl_elem_add en sound/core/control.c en la implementación del control ALSA en el kernel de Linux anterior a 3.15.2 no gestiona debidamente el valor user_ctl_count, lo que permite a usuarios locales causar una denegación de servicio (desbordamiento de enteros y evadir el limite) mediante el aprovechamiento de acceso /dev/snd/controlCX para un numero largo de llamadas SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl. A use-after-free flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled user controls.
