Xen 4.2.x and 4.3.x, when nested virtualization is disabled, does not properly check the emulation paths for 1 VMLAUNCH and 2 VMRESUME, which allows local HVM guest users to cause a denial of service host crash via unspecified vectors related to "guest VMX instruction execution."...

CVE-2013-4551

Xen 4.2.x and 4.3.x, when nested virtualization is disabled, does not properly check the emulation paths for 1 VMLAUNCH and 2 VMRESUME, which allows local HVM guest users to cause a denial of service host crash via unspecified vectors related to "guest VMX instruction execution."...

Android 4.2.x Superuser Unsanitized Environment Vulnerability

Vulnerable releases of several common Android Superuser packages may allow malicious Android applications to execute arbitrary commands as root without notifying the device owner. This advisoriy documents PATH and BOOTCLASSPATH vulnerabilities. Vulnerable releases of several common Android...

Android 4.2.x Superuser Shell Character Escape

Vulnerable releases of two common Android Superuser packages may allow malicious Android applications to execute arbitrary commands as root, either without prompting the user or after the user has denied the request: - CyanogenMod/ClockWorkMod/Koush Superuser current releases, including v1.0.2.1 ...

Host crash due to guest VMX instruction execution

ISSUE DESCRIPTION Permission checks on the emulation paths intended for guests using nested virtualization for VMLAUNCH and VMRESUME were deferred too much. The hypervisor would try to use internal state which is not set up unless nested virtualization is actually enabled for a guest. IMPACT A...

CVE-2013-4416

The Ocaml xenstored implementation oxenstored in Xen 4.1.x, 4.2.x, and 4.3.x allows local guest domains to cause a denial of service domain shutdown via a large message reply...

CVE-2013-1734

Cross-site request forgery CSRF vulnerability in attachment.cgi in Bugzilla 2.x, 3.x, and 4.0.x before 4.0.11; 4.1.x and 4.2.x before 4.2.7; and 4.3.x and 4.4.x before 4.4.1 allows remote attackers to hijack the authentication of arbitrary users for requests that commit an attachment change via a...

CVE-2013-4370

The ocaml binding for the xcvcpugetaffinity function in Xen 4.2.x and 4.3.x frees certain memory that may still be intended for use, which allows local users to cause a denial of service heap corruption and crash and possibly execute arbitrary code via unspecified vectors that trigger a 1...

Design/Logic Flaw

Use-after-free vulnerability in the libxllistcpupool function in the libxl toolstack library in Xen 4.2.x and 4.3.x, when running "under memory pressure," returns the original pointer when the realloc function fails, which allows local users to cause a denial of service heap corruption and crash...

CVE-2013-4370

The ocaml binding for the xcvcpugetaffinity function in Xen 4.2.x and 4.3.x frees certain memory that may still be intended for use, which allows local users to cause a denial of service heap corruption and crash and possibly execute arbitrary code via unspecified vectors that trigger a 1...

Double free

The ocaml binding for the xcvcpugetaffinity function in Xen 4.2.x and 4.3.x frees certain memory that may still be intended for use, which allows local users to cause a denial of service heap corruption and crash and possibly execute arbitrary code via unspecified vectors that trigger a 1...

Null pointer dereference

The xluvifparserate function in the libxlu library in Xen 4.2.x and 4.3.x allows local users to cause a denial of service NULL pointer dereference by using the "@" character as the VIF rate configuration...

CVE-2013-4371

CVE-2013-4371 affects Xen 4.2.x and 4.3.x where libxl_list_cpupool exhibits a use-after-free when memory is tight; a failed realloc returns the original pointer, enabling heap corruption and potential local denial of service or arbitrary code execution. SUSE advisory SUSE-SU-2013:1774-1 notes Xen...

use-after-free in libxl_list_cpupool under memory pressure

ISSUE DESCRIPTION If realloc3 fails then libxllistcpupool will incorrectly return the now-free original pointer. IMPACT An attacker may be able to cause a multithreaded toolstack using this function to race against itself leading to heap corruption and a potential DoS. Depending on the malloc...

misplaced free in ocaml xc_vcpu_getaffinity stub

ISSUE DESCRIPTION The ocaml binding for the xcvcpugetaffinity function incorrectly frees a pointer before using it and subsequently freeing it again afterwards. The code therefore contains a use-after-free and double-free flaws. IMPACT An attacker may be able to cause a multithreaded toolstack...

possible null dereference when parsing vif ratelimiting info

ISSUE DESCRIPTION The libxlu library function xluvifparserate does not properly handle inputs which consist solely of the '@' character, leading to a NULL pointer dereference. IMPACT A toolstack which allows untrusted users to specify an arbitrary configuration for the VIF rate can be subjected t...

CVE-2013-2072

Buffer overflow in the Python bindings for the xcvcpusetaffinity call in Xen 4.0.x, 4.1.x, and 4.2.x allows local administrators with permissions to configure VCPU affinity to cause a denial of service memory corruption and xend toolstack crash and possibly gain privileges via a crafted cpumap...

CVE-2013-2077

Xen 4.0.x, 4.1.x, and 4.2.x does not properly restrict the contents of a XRSTOR, which allows local PV guest users to cause a denial of service unhandled exception and hypervisor crash via unspecified vectors...

CVE-2013-2211

The libxenlight libxl toolstack library in Xen 4.0.x, 4.1.x, and 4.2.x uses weak permissions for xenstore keys for paravirtualised and emulated serial console devices, which allows local guest administrators to modify the xenstore value via unspecified vectors...
