https://notcve.org/view.php?id=CVE-2015-8923
The process_extra function in libarchive before 3.2.0 uses the size field and a signed number in an offset, which allows remote attackers to cause a denial of service (crash) via a crafted zip file. La función process_extra en libarchive en versiones anteriores a 3.2.0 utiliza el campo de tamaño y un número con signo en un desplazamiento, lo que permite a atacantes remotos provocar una denegación de servicio (caída) a través de un archivo zip manipulado. A vulnerability was found in libarchive. A specially crafted ZIP file could cause a few bytes of application memory in a 256-byte region to be disclosed. • http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00025.html http://rhn.redhat.com/errata/RHSA-2016-1844.html http://www.debian.org/security/2016/dsa-3657 http://www.openwall.com/lists/oss-security/2016/06/17/2 http://www.openwall.com/lists/oss-security/2016/06/17/5 http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.securityfocus.com/bid/91309 http://www.ubuntu.com/usn/USN-3033-1 https://blog.fuzzing-project. • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •

The archive_read_format_tar_read_header function in archive_read_support_format_tar.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted tar file. La función archive_read_format_tar_read_header en archive_read_support_format_tar.c en libarchive en versiones anteriores a 3.2.0 permite a atacantes remotos provocar una denegación de servicio (lectura fuera de límites) a través de un archivo tar manipulado. A vulnerability was found in libarchive. A specially crafted TAR file could trigger an out-of-bounds read, potentially causing the application to disclose a small amount of application memory. • http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00025.html http://rhn.redhat.com/errata/RHSA-2016-1844.html http://www.debian.org/security/2016/dsa-3657 http://www.openwall.com/lists/oss-security/2016/06/17/2 http://www.openwall.com/lists/oss-security/2016/06/17/5 http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.securityfocus.com/bid/91308 http://www.ubuntu.com/usn/USN-3033-1 https://blog.fuzzing-project. • CWE-125: Out-of-bounds Read •
CVSS: 7.8EPSS: 0%CPEs: 26EXPL: 5CVE-2016-4997 – Linux Kernel 4.6.3 Netfilter Privilege Escalation
https://notcve.org/view.php?id=CVE-2016-4997
The compat IPT_SO_SET_REPLACE and IP6T_SO_SET_REPLACE setsockopt implementations in the netfilter subsystem in the Linux kernel before 4.6.3 allow local users to gain privileges or cause a denial of service (memory corruption) by leveraging in-container root access to provide a crafted offset value that triggers an unintended decrement. Las implementaciones de compat IPT_SO_SET_REPLACE y IP6T_SO_SET_REPLACE setsockopt en el subsistema netfilter en el kernel de Linux antes de 4.6.3 permiten a los usuarios locales obtener privilegios o provocar una denegación de servicio (corrupción de memoria) aprovechando el acceso del root en el contenedor para proporcionar un valor de compensación manipulado que desencadena una disminución no intencionada. A flaw was discovered in processing setsockopt for 32 bit processes on 64 bit systems. This flaw will allow attackers to alter arbitrary kernel memory when unloading a kernel module. This action is usually restricted to root-privileged users but can also be leveraged if the kernel is compiled with CONFIG_USER_NS and CONFIG_NET_NS and the user is granted elevated privileges. • https://www.exploit-db.com/exploits/40489 https://www.exploit-db.com/exploits/40435 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ce683e5f9d045e5d67d1312a42b359cb2ab2a13c http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00061.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http:/ • CWE-20: Improper Input Validation CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 7.8EPSS: 0%CPEs: 17EXPL: 0CVE-2016-4470 – kernel: Uninitialized variable in request_key handling causes kernel crash in error handling path
https://notcve.org/view.php?id=CVE-2016-4470
The key_reject_and_link function in security/keys/key.c in the Linux kernel through 4.6.3 does not ensure that a certain data structure is initialized, which allows local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command. La función key_reject_and_link en security/keys/key.c en el kernel de Linux hasta la versión 4.6.3 no asegura que cierta estructura de datos esté inicializada, lo que permite a usuarios locales provocar una denegación de servicio (caída del sistema) a través de vectores involucrando un comando keyctl request2 manipulado. A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=38327424b40bcebe2de92d07312c89360ac9229a http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00009.html http://lists.opensuse.org • CWE-253: Incorrect Check of Function Return Value •
CVSS: 8.1EPSS: 0%CPEs: 22EXPL: 1CVE-2016-1583 – Linux Kernel - 'ecryptfs' '/proc/$pid/environ' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2016-1583
The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling. La función ecryptfs_privileged_open en fs/ecryptfs/kthread.c en el kernel de Linux en versiones anteriores a 4.6.3 permite a usuarios locales obtener privilegios o provocar una denegación de servicio (consumo de memoria de pila) a través de vectores involucrados con llamadas mmap manipuladas para nombres de ruta /proc, que conduce a una página de error recursiva manipulada. It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system. There is a stack overflow in Linux via ecryptfs and /proc/$pid/environ. • https://www.exploit-db.com/exploits/39992 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2f36db71009304b3f0b95afacd8eba1f9f046b87 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f5364c150aa645b3d7daa21b5c0b9feaa1c9cd6d http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opens • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •
