1 CVE-2011-3262 399 DoS 2011-08-19 2013-10-10
2.1
None Local Low Not required None None Partial
tools/libxc/xc_dom_bzimageloader.c in Xen 3.2, 3.3, 4.0, and 4.1 allows local users to cause a denial of service (management software infinite loop and management domain resource consumption) via unspecified vectors related to "Lack of error checking in the decompression loop."
2 CVE-2011-2883 20 Exec Code 2011-07-21 2011-07-22
9.3
None Remote Medium Not required Complete Complete Complete
The NSEPA.NsepaCtrl.1 ActiveX control in nsepa.ocx in Citrix Access Gateway Enterprise Edition 8.1 before 8.1-67.7, 9.0 before 9.0-70.5, and 9.1 before 9.1-96.4 attempts to validate signed DLLs by checking the certificate subject, not the signature, which allows man-in-the-middle attackers to execute arbitrary code via HTTP header data referencing a DLL that was signed with a crafted certificate.
3 CVE-2011-2882 119 Exec Code Overflow 2011-07-21 2011-09-21
9.3
None Remote Medium Not required Complete Complete Complete
Stack-based buffer overflow in the NSEPA.NsepaCtrl.1 ActiveX control in nsepa.ocx in Citrix Access Gateway Enterprise Edition 8.1 before 8.1-67.7, 9.0 before 9.0-70.5, and 9.1 before 9.1-96.4 allows remote attackers to execute arbitrary code via crafted HTTP header data.
4 CVE-2011-1898 264 +Priv 2011-08-12 2011-10-25
7.4
None Local Network Medium Single system Complete Complete Complete
Xen 4.1 before 4.1.1 and 4.0 before 4.0.2, when using PCI passthrough on Intel VT-d chipsets that do not have interrupt remapping, allows guest OS users to gain host OS privileges by "using DMA to generate MSI interrupts by writing to the interrupt injection registers."
5 CVE-2011-1583 189 DoS Exec Code Overflow 2011-08-12 2011-08-23
6.9
None Local Medium Not required Complete Complete Complete
Multiple integer overflows in tools/libxc/xc_dom_bzimageloader.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 out-of-bounds read in the loader involving unspecified length fields.
6 CVE-2011-1101 DoS 2011-02-25 2011-03-10
6.8
None Remote Medium Not required Partial Partial Partial
Multiple unspecified vulnerabilities in a third-party component of the Citrix Licensing Administration Console 11.6, formerly License Management Console, allow remote attackers to (1) access unauthorized "license administration functionality" or (2) cause a denial of service via unknown vectors.
7 CVE-2010-4566 1 Exec Code 2011-01-14 2011-09-21
9.3
None Remote Medium Not required Complete Complete Complete
The web authentication form in the NT4 authentication component in Citrix Access Gateway Enterprise Edition 9.2-49.8 and earlier, and the NTLM authentication component in Access Gateway Standard and Advanced Editions before Access Gateway 5.0, allows attackers to execute arbitrary commands via shell metacharacters in the password field.
8 CVE-2010-4255 DoS 2011-01-24 2011-10-25
6.1
None Local Network Low Not required None None Complete
The fixup_page_fault function in arch/x86/traps.c in Xen 4.0.1 and earlier on 64-bit platforms, when paravirtualization is enabled, does not verify that kernel mode is used to call the handle_gdt_ldt_mapping_fault function, which allows guest OS users to cause a denial of service (host OS BUG_ON) via a crafted memory access.
9 CVE-2010-4247 20 DoS 2011-01-10 2012-03-19
5.5
None Local Network Low Single system None None Complete
The do_block_io_op function in (1) drivers/xen/blkback/blkback.c and (2) drivers/xen/blktap/blktap.c in Xen before 3.4.0 for the Linux kernel 2.6.18, and possibly other versions, allows guest OS users to cause a denial of service (infinite loop and CPU consumption) via a large production request index to the blkback or blktap back-end drivers. NOTE: some of these details are obtained from third party information.
10 CVE-2010-4238 264 DoS 2011-01-22 2012-03-19
5.5
None Local Network Low Single system None None Complete
The vbd_create function in Xen 3.1.2, when the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 is used, allows guest OS users to cause a denial of service (host OS panic) via an attempted access to a virtual CD-ROM device through the blkback driver. NOTE: some of these details are obtained from third party information.
