CVSS: 7.2EPSS: 0%CPEs: 13EXPL: 3CVE-2014-4943 – Linux Kernel 3.15.6 - PPP-over-L2TP Socket Level Handling Crash (PoC)
https://notcve.org/view.php?id=CVE-2014-4943
The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel through 3.15.6 allows local users to gain privileges by leveraging data-structure differences between an l2tp socket and an inet socket. La funcionalidad PPPoL2TP en net/l2tp/l2tp_ppp.c en el kernel de Linux hasta 3.15.6 permite a usuarios locales ganar privilegios mediante el aprovechamiento de diferencias de la estructura de datos entre un socket l2tp y un socket inet. A flaw was found in the way the pppol2tp_setsockopt() and pppol2tp_getsockopt() functions in the Linux kernel's PPP over L2TP implementation handled requests with a non-SOL_PPPOL2TP socket option level. A local, unprivileged user could use this flaw to escalate their privileges on the system. • https://www.exploit-db.com/exploits/36267 https://github.com/redes-2015/l2tp-socket-bug http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=3cf521f7dc87c031617fd47e4b7aa2593c2f3daf 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://lists.opensuse.org/opensuse-security-announce/2014-10/msg00006.html http://lists.opensuse.org/opensuse-security-announce • CWE-269: Improper Privilege Management •
CVSS: 6.9EPSS: 0%CPEs: 11EXPL: 4CVE-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 https://github.com/vnik5287/cve-2014-4699-ptrace 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 htt • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-642: External Control of Critical State Data •

Race condition in the tlv handler functionality in the snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allows local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access.

The sctp_association_free function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not properly manage a certain backlog value, which allows remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet. La función sctp_association_free en net/sctp/associola.cen en el kernel de Linux anterior a 3.15.2 no gestiona debidamente cierto valor de backlogs, lo que permite a atacantes remotos causar una denegación de servicio (interrupción del socket) mediante un paquete SCTP manipulado. An integer underflow flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation processed certain COOKIE_ECHO packets. By sending a specially crafted SCTP packet, a remote attacker could use this flaw to prevent legitimate connections to a particular SCTP server socket to be made. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=d3217b15a19a4779c39b212358a5c71d725822ee http://linux.oracle.com/errata/ELSA-2014-3068.html http://linux.oracle.com/errata/ELSA-2014-3069.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://secunia.com/advisories/59777 http://secunia&# • CWE-190: Integer Overflow or Wraparound •
