CVSS: 6.2EPSS: 0%CPEs: 11EXPL: 1CVE-2015-0239 – kernel: kvm: insufficient sysenter emulation when invoked from 16-bit code
https://notcve.org/view.php?id=CVE-2015-0239
The em_sysenter function in arch/x86/kvm/emulate.c in the Linux kernel before 3.18.5, when the guest OS lacks SYSENTER MSR initialization, allows guest OS users to gain guest OS privileges or cause a denial of service (guest OS crash) by triggering use of a 16-bit code segment for emulation of a SYSENTER instruction. La función em_sysenter en arch/x86/kvm/emulate.c en el kernel de Linux anterior a 3.18.5, cuando al sistema operativo invitado le falta la inicialización SYSENTER MSR, permite a usuarios del sistema operativo invitado ganar privilegios del sistema operativo invitado o causar una denegación de servicio (caída del sistema operativo invitado) mediante la provocación del uso de un segmento de código de 16 bits para la emulación de una instrucción SYSENTER. It was found that the Linux kernel KVM subsystem's sysenter instruction emulation was not sufficient. An unprivileged guest user could use this flaw to escalate their privileges by tricking the hypervisor to emulate a SYSENTER instruction in 16-bit mode, if the guest OS did not initialize the SYSENTER model-specific registers (MSRs). Note: Certified guest operating systems for Red Hat Enterprise Linux with KVM do initialize the SYSENTER MSRs and are thus not vulnerable to this issue when running on a KVM hypervisor. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=f3747379accba8e95d70cec0eae0582c8c182050 http://permalink.gmane.org/gmane.linux.kernel.commits.head/502245 http://rhn.redhat.com/errata/RHSA-2015-1272.html http://www.debian.org/security/2015/dsa-3170 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.18.5 http://www.mandriva.com/security/advisories?name=MDVSA-2015:058 http://www.openwall.com/lists/oss-security/2015/01/27/6 http://www • CWE-269: Improper Privilege Management CWE-391: Unchecked Error Condition •

The Crypto API in the Linux kernel before 3.18.5 allows local users to load arbitrary kernel modules via a bind system call for an AF_ALG socket with a module name in the salg_name field, a different vulnerability than CVE-2014-9644. La API Crypto en el kernel de Linux anterior a 3.18.5 permite a usuarios locales cargar módulos del kernel arbitrarios a través de una llamada al sistema de enlaces para un socket AF_ALG con un nombre de módulo en el campo salg_name, una vulnerabilidad diferente a CVE-2014-9644. A flaw was found in the way the Linux kernel's Crypto subsystem handled automatic loading of kernel modules. A local user could use this flaw to load any installed kernel module, and thus increase the attack surface of the running kernel. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=5d26a105b5a73e5635eae0629b42fa0a90e07b7b http://rhn.redhat.com/errata/RHSA-2016-0068.html http://www.debian.org/security/2015/dsa-3170 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.18.5 http://www.mandriva.com/security/advisories?name=MDVSA-2015:057 http://www.mandriva.com/security/advisories?name=MDVSA-2015:058 http://www.openwall.com/lists/oss-security/2015/01/24/4 http://www. • CWE-269: Improper Privilege Management CWE-749: Exposed Dangerous Method or Function •

Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST." Desbordamiento de buffer basado en memoria dinámica en la función __nss_hostname_digits_dots en glibc 2.2, y otras versiones 2.x anteriores a 2.18, permite a atacantes dependientes de contexto ejecutar código arbitrario a través de vectores relacionados con la funciín (1) gethostbyname o (2) gethostbyname2, también conocido como 'GHOST.' A heap-based buffer overflow was found in glibc's __nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() glibc function calls. A remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application.
