CVSS: 7.5EPSS: 71%CPEs: 67EXPL: 1CVE-2015-3329 – php: buffer overflow in phar_set_inode()
https://notcve.org/view.php?id=CVE-2015-3329
Multiple stack-based buffer overflows in the phar_set_inode function in phar_internal.h in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 allow remote attackers to execute arbitrary code via a crafted length value in a (1) tar, (2) phar, or (3) ZIP archive. Múltiples desbordamientos de buffer basado en pila en la función phar_set_inode en phar_internal.h en PHP anterior a 5.4.40, 5.5.x anterior a 5.5.24, y 5.6.x anterior a 5.6.8 permiten a atacantes remotos ejecutar código arbitrario a través de un valor de longitud manipulado en un archivo (1) tar, (2) phar, o (3) ZIP. A buffer overflow flaw was found in the way PHP's Phar extension parsed Phar archives. A specially crafted archive could cause PHP to crash or, possibly, execute arbitrary code when opened. • http://git.php.net/?p=php-src.git%3Ba=commit%3Bh=f59b67ae50064560d7bfcdb0d6a8ab284179053c http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00005.html http://php.net/ChangeLog-5.php http://rhn.redhat.com/errata/RHSA-2015-1066.html http://rhn.redhat.com/errata& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2013-7421
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 •

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 •
