CVSS: 10.0EPSS: 3%CPEs: 19EXPL: 0CVE-2016-0749 – spice: heap-based memory corruption within smartcard handling
https://notcve.org/view.php?id=CVE-2016-0749
The smartcard interaction in SPICE allows remote attackers to cause a denial of service (QEMU-KVM process crash) or possibly execute arbitrary code via vectors related to connecting to a guest VM, which triggers a heap-based buffer overflow. La interacción smartcard en SPICE permite a atacantes remotos provocar un denegación de servicio (caída del proceso QEMU-KVM) o ejecutar, posiblemente, un código arbitrario a través de véctores relacionados con conectarse con un invitado VM, lo que ejecuta un desbordamiento de bufer basado en memoria dinámica. A memory allocation flaw, leading to a heap-based buffer overflow, was found in spice's smartcard interaction, which runs under the QEMU-KVM context on the host. A user connecting to a guest VM using spice could potentially use this flaw to crash the QEMU-KVM process or execute arbitrary code with the privileges of the host's QEMU-KVM process. • http://lists.opensuse.org/opensuse-updates/2016-07/msg00003.html http://lists.opensuse.org/opensuse-updates/2016-07/msg00004.html http://www.debian.org/security/2016/dsa-3596 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.ubuntu.com/usn/USN-3014-1 https://access.redhat.com/errata/RHSA-2016:1204 https://access.redhat.com/errata/RHSA-2016:1205 https://security.gentoo.org/glsa/201606-05 https://access.redhat.com/security/cve/CVE-2016 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

The read_boot function in boot.c in dosfstools before 4.0 allows attackers to cause a denial of service (crash) via a crafted filesystem, which triggers a heap-based buffer overflow in the (1) read_fat function or an out-of-bounds heap read in (2) get_fat function. La función read_boot en boot.c en dosfstools en versiones anteriores a 4.0 permite a atacantes provocar una denegación de servicio (caída) a través de un archivo de sistema manipulado, lo que desencadena un desbordamiento de buffer basado en memoria dinámica en la función (1) read_fat o una lectura de memoria fuera de los límites en la función (2) get_fat. • http://lists.opensuse.org/opensuse-updates/2016-06/msg00001.html http://lists.opensuse.org/opensuse-updates/2016-09/msg00014.html http://www.securityfocus.com/bid/90311 http://www.ubuntu.com/usn/USN-2986-1 https://blog.fuzzing-project.org/44-dosfstools-fsck.vfat-Several-invalid-memory-accesses.html https://github.com/dosfstools/dosfstools/commit/e8eff147e9da1185f9afd5b25948153a3b97cf52 https://github.com/dosfstools/dosfstools/issues/25 https://github.com/dosfstools/dosfstools/issues/26 https://lists • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The set_fat function in fat.c in dosfstools before 4.0 might allow attackers to corrupt a FAT12 filesystem or cause a denial of service (invalid memory read and crash) by writing an odd number of clusters to the third to last entry on a FAT12 filesystem, which triggers an "off-by-two error." La función set_fat en fat.c en dosfstools en versiones anteriores a 4.0 podría permitir a atacantes corromper un sistema de archivos FAT12 o provocar una denegación de servicio (lectura de memoria no válida y caída) escribiendo un número impar de clusters desde la tercera a la última entrada en un sistema de archivos FAT12, lo que desencadena un "off-by-two error". • http://lists.opensuse.org/opensuse-updates/2016-06/msg00001.html http://lists.opensuse.org/opensuse-updates/2016-09/msg00014.html http://www.securityfocus.com/bid/90311 http://www.ubuntu.com/usn/USN-2986-1 https://blog.fuzzing-project.org/44-dosfstools-fsck.vfat-Several-invalid-memory-accesses.html https://github.com/dosfstools/dosfstools/commit/07908124838afcc99c577d1d3e84cef2dbd39cb7 https://github.com/dosfstools/dosfstools/issues/12 https://github.com/dosfstools/dosfstools/releases/tag/v4.0 https:&#x • CWE-189: Numeric Errors •
CVSS: 9.8EPSS: 0%CPEs: 26EXPL: 0CVE-2016-0718 – expat: Out-of-bounds heap read on crafted input causing crash
https://notcve.org/view.php?id=CVE-2016-0718
Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow. Expat permite a atacantes dependientes del contexto provocar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de un documento de entrada mal formado, lo que desencadena un desbordamiento de buffer. An out-of-bounds read flaw was found in the way Expat processed certain input. A remote attacker could send specially crafted XML that, when parsed by an application using the Expat library, would cause that application to crash or, possibly, execute arbitrary code with the permission of the user running the application. • http://lists.apple.com/archives/security-announce/2016/Jul/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2016-08 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

Off-by-one error in the tokenadd function in jv_parse.c in jq allows remote attackers to cause a denial of service (crash) via a long JSON-encoded number, which triggers a heap-based buffer overflow. Error por un paso en la función tokenadd en jv_parse.c en jq permite a atacantes remotos provocar una denegación de servicio (caída) a través de un número largo codificado en JSON, lo que desencadena un desbordamiento de buffer basado en memoria dinámica. A heap-based buffer overflow flaw was found in jq's tokenadd() function.
