CVSS: 2.1EPSS: 0%CPEs: 12EXPL: 0CVE-2014-8136 – libvirt: local denial of service in qemu/qemu_driver.c
https://notcve.org/view.php?id=CVE-2014-8136
The (1) qemuDomainMigratePerform and (2) qemuDomainMigrateFinish2 functions in qemu/qemu_driver.c in libvirt do not unlock the domain when an ACL check fails, which allow local users to cause a denial of service via unspecified vectors. Las funciones (1) qemuDomainMigratePerform y (2) qemuDomainMigrateFinish2 en qemu/qemu_driver.c en libvirt no desbloquea el dominio cuando una comprobación de ACL falla, lo que permite a usuarios locales provocar una denegación de servicio a través de vectores sin especificar. It was found that QEMU's qemuDomainMigratePerform() and qemuDomainMigrateFinish2() functions did not correctly perform a domain unlock on a failed ACL check. A remote attacker able to establish a connection to libvirtd could use this flaw to lock a domain of a more privileged user, causing a denial of service. • http://advisories.mageia.org/MGASA-2015-0002.html http://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=2bdcd29c713dfedd813c89f56ae98f6f3898313d http://lists.opensuse.org/opensuse-updates/2015-01/msg00003.html http://lists.opensuse.org/opensuse-updates/2015-01/msg00005.html http://rhn.redhat.com/errata/RHSA-2015-0323.html http://secunia.com/advisories/61111 http://www.mandriva.com/security/advisories?name=MDVSA-2015:023 http://www.mandriva.com/security/advisories?name=MDVSA-2015:070 http:// • CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 3.5EPSS: 0%CPEs: 30EXPL: 0CVE-2014-5353 – krb5: NULL pointer dereference when using a ticket policy name as a password policy name
https://notcve.org/view.php?id=CVE-2014-5353
The krb5_ldap_get_password_policy_from_dn function in plugins/kdb/ldap/libkdb_ldap/ldap_pwd_policy.c in MIT Kerberos 5 (aka krb5) before 1.13.1, when the KDC uses LDAP, allows remote authenticated users to cause a denial of service (daemon crash) via a successful LDAP query with no results, as demonstrated by using an incorrect object type for a password policy. La función krb5_ldap_get_password_policy_from_dn en plugins/kdb/ldap/libkdb_ldap/ldap_pwd_policy.c en MIT Kerberos 5 (también conocido como krb5) anterior a 1.13.1, cuando el KDC utiliza LDAP, permite a usuarios remotos autenticados causar una denegación de servicio (caída del demonio) a través de una consulta LDAP con éxito pero sin resultados, tal y como fue demostrado mediante el uso de un tipo de objeto incorrecto para una política de contraseñas. If kadmind were used with an LDAP back end for the KDC database, a remote, authenticated attacker who has the permissions to set the password policy could crash kadmind by attempting to use a named ticket policy object as a password policy for a principal. • http://advisories.mageia.org/MGASA-2014-0536.html http://lists.fedoraproject.org/pipermail/package-announce/2015-April/155828.html http://lists.opensuse.org/opensuse-updates/2015-03/msg00061.html http://rhn.redhat.com/errata/RHSA-2015-0439.html http://rhn.redhat.com/errata/RHSA-2015-0794.html http://www.mandriva.com/security/advisories?name=MDVSA-2015:009 http://www.oracle.com/technetwork/topics/security/bulletinapr2015-2511959.html http://www.securityfocus.com/bid/71679 http://www.sec • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2014-8964
Heap-based buffer overflow in PCRE 8.36 and earlier allows remote attackers to cause a denial of service (crash) or have other unspecified impact via a crafted regular expression, related to an assertion that allows zero repeats. Desbordamiento de buffer basado en memoria dinámica en PCRE 8.36 y anteriores permite a atacantes remotos causar una denegación de servicio (caída) o tener otro impacto no especificado a través de una expresión regular manipulada, relacionado con una aserción que permite cero repeticiones. A flaw was found in the way PCRE handled certain malformed regular expressions. This issue could cause an application (for example, Konqueror) linked against PCRE to crash while parsing malicious regular expressions. • http://advisories.mageia.org/MGASA-2014-0534.html http://bugs.exim.org/show_bug.cgi?id=1546 http://lists.fedoraproject.org/pipermail/package-announce/2014-December/145843.html http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147474.html http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147511.html http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147516.html http://lists.opensuse.org/opensuse-updates/2015-05/msg00014.html http://rhn.redhat • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 3.3EPSS: 0%CPEs: 8EXPL: 1CVE-2014-8134 – kernel: x86: espfix not working for 32-bit KVM paravirt guests
https://notcve.org/view.php?id=CVE-2014-8134
The paravirt_ops_setup function in arch/x86/kernel/kvm.c in the Linux kernel through 3.18 uses an improper paravirt_enabled setting for KVM guest kernels, which makes it easier for guest OS users to bypass the ASLR protection mechanism via a crafted application that reads a 16-bit value. La función paravirt_ops_setup en arch/x86/kernel/kvm.c en el kernel de Linux hasta 3.18 utiliza una configuración paravirt_enabled indebida para los kernels KVM invitados, lo que facilita a usuarios invitados del sistema operativo evadir el mecanismo de protección ASLR a través de una aplicación manipulada que lee un valor de 16 bits. It was found that the espfix functionality does not work for 32-bit KVM paravirtualized guests. A local, unprivileged guest user could potentially use this flaw to leak kernel stack addresses. • http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://people.canonical.com/~ubuntu-security/cve/2014/CVE-2014-8134.html http://rhn.redhat.com/errata/RHSA-2016-0855.html http://secunia.com/advisories/62336 http://www.oracle.com/technetwork/t •
