Redhat » Enterprise Virtualization Manager : Security Vulnerabilities, CVEs, CVSS score >= 2

A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL < 3, the debug exception is delivered after the transfer to CPL < 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs.

Red Hat Enterprise Virtualization Manager (RHEV-M) before 3.1, when moving disks between storage domains, does not properly wipe-after-delete, which prevents disks from being securely deleted and might allow local users to obtain sensitive information via unspecified vectors.

Multiple untrusted search path vulnerabilities in Red Hat Enterprise Virtualization Manager (RHEV-M) before 3.1, when adding a host, allow local users to gain privileges via a Trojan horse (1) deployUtil.py or (2) vds_bootstrap.py Python module in /tmp/.

Race condition in the SPICE (aka spice-activex) plug-in for Internet Explorer in Red Hat Enterprise Virtualization (RHEV) Manager before 2.2.4 allows local users to create a certain named pipe, and consequently gain privileges, via vectors involving knowledge of the name of this named pipe, in conjunction with use of the ImpersonateNamedPipeClient function.

The snapshot merging functionality in Red Hat Enterprise Virtualization Manager (aka RHEV-M) before 2.2 does not properly pass the postzero parameter during operations on deleted volumes, which allows guest OS users to obtain sensitive information by examining the disk blocks associated with a deleted virtual machine.

In RHEV-M VDC 2.2.0, it was found that the SSL certificate was not verified when using the client-side Red Hat Enterprise Virtualization Manager interface (a Windows Presentation Foundation (WPF) XAML browser application) to connect to the Red Hat Enterprise Virtualization Manager. An attacker on the local network could use this flaw to conduct a man-in-the-middle attack, tricking the user into thinking they are viewing the Red Hat Enterprise Virtualization Manager when the content is actually attacker-controlled, or modifying actions a user requested Red Hat Enterprise Virtualization Manager to perform.
