https://notcve.org/view.php?id=CVE-2016-2857
The net_checksum_calculate function in net/checksum.c in QEMU allows local guest OS users to cause a denial of service (out-of-bounds heap read and crash) via the payload length in a crafted packet. La función net_checksum_calculate en net/checksum.c en QEMU permite a usuarios del SO invitado provocar una denegación de servicio (lectura de memoria dinámica fuera de rango y caída) a través de una longitud de la carga útil en un paquete manipulado. An out-of-bounds read-access flaw was found in the QEMU emulator built with IP checksum routines. The flaw could occur when computing a TCP/UDP packet's checksum, because a QEMU function used the packet's payload length without checking against the data buffer's size. A user inside a guest could use this flaw to crash the QEMU process (denial of service). • http://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=362786f14a753d8a5256ef97d7c10ed576d6572b http://rhn.redhat.com/errata/RHSA-2016-2670.html http://rhn.redhat.com/errata/RHSA-2016-2671.html http://rhn.redhat.com/errata/RHSA-2016-2704.html http://rhn.redhat.com/errata/RHSA-2016-2705.html http://rhn.redhat.com/errata/RHSA-2016-2706.html http://rhn.redhat.com/errata/RHSA-2017-0083.html http://rhn.redhat.com/errata/RHSA-2017-0309.html http://rhn.redhat.com/errata/RHSA- • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
CVSS: 9.8EPSS: 0%CPEs: 25EXPL: 0CVE-2016-1908 – openssh: possible fallback from untrusted to trusted X11 forwarding
https://notcve.org/view.php?id=CVE-2016-1908
The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues on this X11 server, as demonstrated by lack of the SECURITY extension on this X11 server. El cliente en OpenSSH en versiones anteriores a 7.2 no maneja correctamente falló en la generación de cookies para el reenvío X11 no confiable y confía en el servidor X11 local para las decisiones de control de acceso, lo que permite a los clientes remotos X11 activar un fallback y obtener privilegios de reenvío X11 confiables aprovechando los problemas de configuración de este servidor X11, como lo demuestra la falta de la extensión SECURITY en este servidor X11. An access flaw was discovered in OpenSSH; the OpenSSH client did not correctly handle failures to generate authentication cookies for untrusted X11 forwarding. A malicious or compromised remote X application could possibly use this flaw to establish a trusted connection to the local X server, even if only untrusted X11 forwarding was requested. • http://openwall.com/lists/oss-security/2016/01/15/13 http://rhn.redhat.com/errata/RHSA-2016-0465.html http://rhn.redhat.com/errata/RHSA-2016-0741.html http://www.openssh.com/txt/release-7.2 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securityfocus.com/bid/84427 http://www.securitytracker.com/id/1034705 https://anongit.mindrot.org/openssh.git/commit/?id=ed4ce82dbfa8a3a3c8ea6fa0db113c71e234416c https://bugzilla.redhat.com/show_bug.cgi • CWE-284: Improper Access Control CWE-287: Improper Authentication •
CVSS: 5.3EPSS: 0%CPEs: 32EXPL: 0CVE-2015-8629 – krb5: xdr_nullstring() doesn't check for terminating null character
https://notcve.org/view.php?id=CVE-2015-8629
The xdr_nullstring function in lib/kadm5/kadm_rpc_xdr.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 does not verify whether '\0' characters exist as expected, which allows remote authenticated users to obtain sensitive information or cause a denial of service (out-of-bounds read) via a crafted string. La función xdr_nullstring en lib/kadm5/kadm_rpc_xdr.c en kadmind in MIT Kerberos 5 (también conocido como krb5) en versiones anteriores a 1.13.4 y 1.14.x en versiones anteriores a 1.14.1 no verifica si existen caracteres '\0' según lo esperado, lo que permite a usuarios remotos autenticados obtener información sensible o causar una denegación de servicio (lectura fuera de rango) a través de una cadena manipulada. An out-of-bounds read flaw was found in the kadmind service of MIT Kerberos. An authenticated attacker could send a maliciously crafted message to force kadmind to read beyond the end of allocated memory, and write the memory contents to the KDC database if the attacker has write permission, leading to information disclosure. • http://krbdev.mit.edu/rt/Ticket/Display.html?id=8341 http://lists.opensuse.org/opensuse-updates/2016-02/msg00059.html http://lists.opensuse.org/opensuse-updates/2016-02/msg00110.html http://rhn.redhat.com/errata/RHSA-2016-0493.html http://rhn.redhat.com/errata/RHSA-2016-0532.html http://www.debian.org/security/2016/dsa-3466 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html htt • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2015-8631
Multiple memory leaks in kadmin/server/server_stubs.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 allow remote authenticated users to cause a denial of service (memory consumption) via a request specifying a NULL principal name. Múltiples pérdidas de memoria en kadmin/server/server_stubs.c en kadmind en MIT Kerberos 5 (también conocido como krb5) en versiones anteriores a 1.13.4 y 1.14.x en versiones anteriores a 1.14.1 permiten a usuarios remotos autenticados causar una denegación de servicio (consumo de memoria) a través de una solicitud especificando un nombre principal NULL. A memory leak flaw was found in the krb5_unparse_name() function of the MIT Kerberos kadmind service. An authenticated attacker could repeatedly send specially crafted requests to the server, which could cause the server to consume large amounts of memory resources, ultimately leading to a denial of service due to memory exhaustion. • http://krbdev.mit.edu/rt/Ticket/Display.html?id=8343 http://lists.opensuse.org/opensuse-updates/2016-02/msg00059.html http://lists.opensuse.org/opensuse-updates/2016-02/msg00110.html http://rhn.redhat.com/errata/RHSA-2016-0493.html http://rhn.redhat.com/errata/RHSA-2016-0532.html http://www.debian.org/security/2016/dsa-3466 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securitytracker.com/id/1034916 https://github.com/krb5/krb5&# • CWE-401: Missing Release of Memory after Effective Lifetime CWE-772: Missing Release of Resource after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2015-7529
sosreport in SoS 3.x allows local users to obtain sensitive information from sosreport files or gain privileges via a symlink attack on an archive file in a temporary directory, as demonstrated by sosreport-$hostname-$date.tar in /tmp/sosreport-$hostname-$date. sosreport en las versiones 3.x de SoS permite que usuarios locales ibtengan información sensible de archivos sosreport u obtener privilegios mediante un ataque de vínculo simbólico o un archivo de archivado en un directorio temporal. Esto lo demuestra sosreport-$hostname-$date.tar en /tmp/sosreport-$hostname-$date. An insecure temporary file use flaw was found in the way sos created certain sosreport files. A local attacker could possibly use this flaw to perform a symbolic link attack to reveal the contents of sosreport files, or in some cases modify arbitrary files and escalate their privileges on the system. • http://rhn.redhat.com/errata/RHSA-2016-0152.html http://rhn.redhat.com/errata/RHSA-2016-0188.html http://www.securityfocus.com/bid/83162 http://www.ubuntu.com/usn/USN-2845-1 https://access.redhat.com/errata/RHSA-2016:0152 https://access.redhat.com/errata/RHSA-2016:0188 https://bugzilla.redhat.com/show_bug.cgi?id=1282542 https://github.com/sosreport/sos/issues/696 https://access.redhat.com/security/cve/CVE-2015-7529 • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-377: Insecure Temporary File •
