Oracle Linux 5 : ELSA-2014-0926-1: / kernel (ELSA-2014-09261)

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-09261 advisory. - The rdsiwladdrcheck function in net/rds/iw.c in the Linux kernel through 3.14 allows local users to cause a denial of service NULL pointer dereferen...

DEBIAN-CVE-2019-18425

An issue was discovered in Xen through 4.12.x allowing 32-bit PV guest OS users to gain guest OS privileges by installing and using descriptors. There is missing descriptor table limit checking in x86 PV emulation. When emulating certain PV guest operations, descriptor table accesses are performe...

Design/Logic Flaw

The memoryexchange function in common/memory.c in Xen 3.2.x through 4.6.x does not properly hand back pages to a domain, which might allow guest OS administrators to cause a denial of service host crash via unspecified vectors related to domain teardown...

Information leak through version information hypercall

ISSUE DESCRIPTION The code handling certain sub-operations of the HYPERVISORxenversion hypercall fails to fully initialize all fields of structures subsequently copied back to guest memory. Due to this hypervisor stack contents are copied into the destination of the operation, thus becoming visib...

Design/Logic Flaw

The acceleration support for the "REP MOVS" instruction in Xen 4.4.x, 3.2.x, and earlier lacks properly bounds checking for memory mapped I/O MMIO emulated in the hypervisor, which allows local HVM guests to cause a denial of service host crash via unspecified vectors...

CVE-2014-1894

Multiple integer overflows in unspecified suboperations in the flask hypercall in Xen 3.2.x and earlier, when XSM is enabled, allow local users to cause a denial of service processor fault via unspecified vectors, a different vulnerability than CVE-2014-1891, CVE-2014-1892, and CVE-2014-1893...

Integer overflow

Multiple integer overflows in unspecified suboperations in the flask hypercall in Xen 3.2.x and earlier, when XSM is enabled, allow local users to cause a denial of service processor fault via unspecified vectors, a different vulnerability than CVE-2014-1891, CVE-2014-1892, and CVE-2014-1893...

Integer overflow

Multiple integer overflows in tools/libxc/xcdombzimageloader.c in Xen 3.2, 3.3, 4.0, and 4.1 allow local users to cause a denial of service and possibly execute arbitrary code via a crafted paravirtualised guest kernel image that triggers 1 a buffer overflow during a decompression loop or 2 an...

CVE-2008-1943

Buffer overflow in the backend of XenSource Xen Para Virtualized Frame Buffer PVFB 3.0 through 3.1.2 allows local users to cause a denial of service crash and possibly execute arbitrary code via a crafted description of a shared framebuffer...
