CVSS: 6.2EPSS: 0%CPEs: 4EXPL: 1CVE-2014-5045 – kernel: vfs: refcount issues during unmount on symlink
https://notcve.org/view.php?id=CVE-2014-5045
The mountpoint_last function in fs/namei.c in the Linux kernel before 3.15.8 does not properly maintain a certain reference count during attempts to use the umount system call in conjunction with a symlink, which allows local users to cause a denial of service (memory consumption or use-after-free) or possibly have unspecified other impact via the umount program. La función mountpoint_last en fs/namei.c en el kernel de Linux anterior a 3.15.8 no mantiene debidamente cierta cuenta de referencias durante intentos de utilizar la llamada al sistema umount en conjunto con un enlace simbólico, lo que permite a usuarios locales causar una denegación de servicio (consumo de memoria o uso después de liberación) o posiblemente tener otro impacto no especificado a través del programa umount. A flaw was found in the way the Linux kernel's VFS subsystem handled reference counting when performing unmount operations on symbolic links. A local, unprivileged user could use this flaw to exhaust all available memory on the system or, potentially, trigger a use-after-free error, resulting in a system crash or privilege escalation. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=295dc39d941dc2ae53d5c170365af4c9d5c16212 http://rhn.redhat.com/errata/RHSA-2015-0062.html http://secunia.com/advisories/60353 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.15.8 http://www.openwall.com/lists/oss-security/2014/07/24/2 http://www.securityfocus.com/bid/68862 https://bugzilla.redhat.com/show_bug.cgi?id=1122472 https://github.com/torvalds/linux/commit/295dc39d941dc2ae53d5c170365af4 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

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 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/2014-10/msg00007.html http://lists.opensuse.org&# • CWE-269: Improper Privilege Management •
