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 •
CVSS: 7.5EPSS: 7%CPEs: 14EXPL: 0CVE-2015-8630 – krb5: krb5 doesn't check for null policy when KADM5_POLICY is set in the mask
https://notcve.org/view.php?id=CVE-2015-8630
The (1) kadm5_create_principal_3 and (2) kadm5_modify_principal functions in lib/kadm5/srv/svr_principal.c in kadmind in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.4 and 1.14.x before 1.14.1 allow remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) by specifying KADM5_POLICY with a NULL policy name. Las funciones (1) kadm5_create_principal_3 y (2) kadm5_modify_principal en lib/kadm5/srv/svr_principal.c en kadmind en MIT Kerberos 5 (también conocido como krb5) 1.12.x y 1.13.x 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 (referencia a puntero NULL y caída de demonio) mediante la especificación KADM5_POLICY con un nombre de política NULL. A NULL pointer dereference flaw was found in the procedure used by the MIT Kerberos kadmind service to store policies: the kadm5_create_principal_3() and kadm5_modify_principal() function did not ensure that a policy was given when KADM5_POLICY was set. An authenticated attacker with permissions to modify the database could use this flaw to add or modify a principal with a policy set to NULL, causing the kadmind service to crash. • http://krbdev.mit.edu/rt/Ticket/Display.html?id=8342 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-2016-0532.html http://www.debian.org/security/2016/dsa-3466 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securitytracker.com/id/1034915 https://github.com/krb5/krb5/commit/b863de7fbf080b15e347a736fdda0a82d42f4f6b https://access.red • CWE-476: NULL Pointer Dereference •

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 •

The iakerb_gss_export_sec_context function in lib/gssapi/krb5/iakerb.c in MIT Kerberos 5 (aka krb5) 1.14 pre-release 2015-09-14 improperly accesses a certain pointer, which allows remote authenticated users to cause a denial of service (memory corruption) or possibly have unspecified other impact by interacting with an application that calls the gss_export_sec_context function. NOTE: this vulnerability exists because of an incorrect fix for CVE-2015-2696. La función iakerb_gss_export_sec_context en lib/gssapi/krb5/iakerb.c en MIT Kerberos 5 (también conocida como krb5) 1.14 pre-release 2015-09-14 no accede adecuadamente a cierto puntero, lo que permite a usuarios remotos autenticados causar una denegación de servicio (corrupción de memoria) o posiblemente tener otro impacto no especificado al interactuar con una aplicación que llama a la función gss_export_sec_context. NOTA: esta vulnerabilidad existe debido a una solución incorrecta para CVE-2015-2696. • http://krbdev.mit.edu/rt/Ticket/Display.html?id=8273 http://lists.opensuse.org/opensuse-updates/2015-11/msg00116.html http://lists.opensuse.org/opensuse-updates/2015-12/msg00124.html http://www.ubuntu.com/usn/USN-2810-1 https://github.com/krb5/krb5/commit/3db8dfec1ef50ddd78d6ba9503185995876a39fd • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The build_principal_va function in lib/krb5/krb/bld_princ.c in MIT Kerberos 5 (aka krb5) before 1.14 allows remote authenticated users to cause a denial of service (out-of-bounds read and KDC crash) via an initial '\0' character in a long realm field within a TGS request. La función build_principal_va en lib/krb5/krb/bld_princ.c en MIT Kerberos 5 (también conocido como krb5) en versiones anteriores a 1.14 permite a usuarios remotos autenticados provocar una denegación de servicio (lectura fuera de rango y caída de KDC) a través de un carácter inicial '\0' en un campo realm largo dentro de una solicitud TGS. • http://krbdev.mit.edu/rt/Ticket/Display.html?id=8252 http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00022.html http://www.debian.org/security/2015/dsa-3395 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/77581 http://www.securitytracker.com/id/1034084 http://w • CWE-125: Out-of-bounds Read •
