CVE-2012-0217 – FreeBSD - Intel SYSRET Privilege Escalation
https://notcve.org/view.php?id=CVE-2012-0217
The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier, as used in Citrix XenServer 6.0.2 and earlier and other products; Oracle Solaris 11 and earlier; illumos before r13724; Joyent SmartOS before 20120614T184600Z; FreeBSD before 9.0-RELEASE-p3; NetBSD 6.0 Beta and earlier; Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and SP1; and possibly other operating systems, when running on an Intel processor, incorrectly uses the sysret path in cases where a certain address is not a canonical address, which allows local users to gain privileges via a crafted application. NOTE: because this issue is due to incorrect use of the Intel specification, it should have been split into separate identifiers; however, there was some value in preserving the original mapping of the multi-codebase coordinated-disclosure effort to a single identifier. El modo de usuario Scheduler en el núcleo en Microsoft Windows Server v2008 R2 y R2 SP1 y Windows v7 Gold y SP1 sobre la plataforma x64 no maneja adecuadamente solicitudes del sistema, lo que permite a usuarios locales obtener privilegios a través de una aplicación modificada, también conocida como "vulnerabilidad de corrupción de memoria de modo de usuario Scheduler". It was found that the Xen hypervisor implementation as shipped with Red Hat Enterprise Linux 5 did not properly restrict the syscall return addresses in the sysret return path to canonical addresses. An unprivileged user in a 64-bit para-virtualized guest, that is running on a 64-bit host that has an Intel CPU, could use this flaw to crash the host or, potentially, escalate their privileges, allowing them to execute arbitrary code at the hypervisor level. • https://www.exploit-db.com/exploits/46508 https://www.exploit-db.com/exploits/28718 https://www.exploit-db.com/exploits/20861 http://blog.illumos.org/2012/06/14/illumos-vulnerability-patched http://blog.xen.org/index.php/2012/06/13/the-intel-sysret-privilege-escalation http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2012-003.txt.asc http://lists.xen.org/archives/html/xen-announce/2012-06/msg00001.html http://lists.xen.org/archives/html/xen-devel/2012-06 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2008-0960 – SNMPv3 - HMAC Validation error Remote Authentication Bypass
https://notcve.org/view.php?id=CVE-2008-0960
SNMPv3 HMAC verification in (1) Net-SNMP 5.2.x before 5.2.4.1, 5.3.x before 5.3.2.1, and 5.4.x before 5.4.1.1; (2) UCD-SNMP; (3) eCos; (4) Juniper Session and Resource Control (SRC) C-series 1.0.0 through 2.0.0; (5) NetApp (aka Network Appliance) Data ONTAP 7.3RC1 and 7.3RC2; (6) SNMP Research before 16.2; (7) multiple Cisco IOS, CatOS, ACE, and Nexus products; (8) Ingate Firewall 3.1.0 and later and SIParator 3.1.0 and later; (9) HP OpenView SNMP Emanate Master Agent 15.x; and possibly other products relies on the client to specify the HMAC length, which makes it easier for remote attackers to bypass SNMP authentication via a length value of 1, which only checks the first byte. Una comprobación SNMPv3 HMAC en (1) Net-SNMP versión 5.2.x anterior a 5.2.4.1, versión 5.3.x anterior a 5.3.2.1 y versión 5.4.x anterior a 5.4.1.1; (2) UCD-SNMP; (3) eCos; (4) C-series versión 1.0.0 hasta 2.0.0 de Juniper Session and Resource Control (SRC); (5) Data de NetApp (también se conoce como Network Appliance) ONTAP versiones 7.3RC1 y 7.3RC2; (6) SNMP Research versión anterior a 16.2; (7) múltiples productos Cisco IOS, CatOS, ACE y Nexus; (8) Ingate Firewall versión 3.1.0 y posterior y SIParator versión 3.1.0 y posterior; (9) HP OpenView SNMP Emanate Master Agent versión 15.x; y posiblemente otros productos dependen del cliente para especificar la longitud del HMAC, lo que facilita que los atacantes remotos omitan la autenticación SNMP por medio de un valor de longitud de 1, que solo comprueba el primer byte. • https://www.exploit-db.com/exploits/5790 http://lists.apple.com/archives/security-announce/2008//Jun/msg00002.html http://lists.ingate.com/pipermail/productinfo/2008/000021.html http://lists.opensuse.org/opensuse-security-announce/2008-08/msg00000.html http://marc.info/?l=bugtraq&m=127730470825399&w=2 http://rhn.redhat.com/errata/RHSA-2008-0528.html http://secunia.com/advisories/30574 http://secunia.com/advisories/30596 http://secunia.com/advisories/30612 http://secunia.c • CWE-287: Improper Authentication •
