Integer overflow in Git before 2.7.4 allows remote attackers to execute arbitrary code via a (1) long filename or (2) many nested trees, which triggers a heap-based buffer overflow.

revision.c in git before 2.7.4 uses an incorrect integer data type, which allows remote attackers to execute arbitrary code via a (1) long filename or (2) many nested trees, leading to a heap-based buffer overflow.

All existing releases of GraphicsMagick and ImageMagick support a file open syntax where if the first character of the file specification is a '|', then the remainder of the filename is passed to the shell for execution using the POSIX popen(3C) function. File opening is handled by an OpenBlob() function in the source file blob.c. Unlike the vulnerability described by CVE-2016-3714, this functionality is supported by the core file opening function rather than a delegates subsystem usually used to execute external programs.

The build package before 20171128 did not check directory names during extraction of build results that allowed untrusted builds to write outside of the target system,allowing escape out of buildroots.

It was discovered that the RMI (Java Remote Method Invocation) server implementation in the JMX (Java Management Extensions) component of OpenJDK did not restrict which classes can be deserialized when deserializing authentication credentials. A remote unauthenticated attacker able to connect to a JMX port could possibly use this flaw trigger deserialization flaws.

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.

The following flaw was reported for IBM JDK:

A flaw in the IBM J9 JVM allows code to invoke non-public interface methods under certain circumstances. Untrusted code could potentially exploit this. This could lead to sensitive data being exposed to an attacker, or the attacker being able to inject bad data.

This flaw could allow an untrusted Java application or applet to bypass certain Java sandbox restrictions.

Issue was fixed in IBM JDK 6 SR16-FP20, 7 SR9-FP30, 7R1 SR3-FP30, and 8 SR2-FP10.

named in ISC BIND 9.x before 9.9.8-P4 and 9.10.x before 9.10.3-P4 does not properly handle DNAME records when parsing fetch reply messages, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed packet to the rndc (aka control channel) interface, related to alist.c and sexpr.c.

Integer overflow in the VNC display driver in QEMU before 2.1.0 allows attachers to cause a denial of service (process crash) via a CLIENTCUTTEXT message, which triggers an infinite loop.

ISSUE DESCRIPTION =================

Xen PCI backend driver does not perform proper sanity checks on the device's state.

Which in turn allows the generic MSI code (called by Xen PCI backend) to be called incorrectly leading to hitting BUG conditions or causing NULL pointer exceptions in the MSI code.

To exploit this the guest can craft specific sequence of XENPCIOP operations which will trigger this.

Furthermore the frontend can also craft an continous stream of XENPCIOPenablemsi which will trigger an continous stream of WARN() messages triggered by the MSI code leading to the logging in the initial domain to exhaust disk space.

Lastly there is also missing check to verify whether the device has memory decoding enabled set at the start of the day leading the initial domain "accesses to the respective MMIO or I/O port ranges would - - on PCI Express devices - [which can] lead to Unsupported Request responses. The treatment of such errors is platform specific." (from XSA-120). Note that if XSA-120 'addendum' patch has been applied this particular sub-issue is not exploitable.

IMPACT ======

Malicious guest administrators can cause denial of service. If driver domains are not in use, the impact is a host crash.

Only x86 systems are vulnerable. ARM systems are not vulnerable.

VULNERABLE SYSTEMS ==================

This bug affects systems using Linux as the driver domain, including non-disaggregated systems using Linux as dom0.

Linux versions v3.1 and onwards are vulnerable due to supporting PCI pass-through backend driver.

PV and HVM guests which have been granted access to physical PCI devices (PCI passthrough') can take advantage of this vulnerability.

Furthermore, the vulnerability is only applicable when the passed-through PCI devices are MSI-capable or MSI-X. (Most modern devices are).

MITIGATION ==========

Not using PCI passthrough for PV and HVM guests. Note that for HVM guests QEMU is used for PCI passthrough - however the toolstack sets up also the 'PV' PCI which the guest can utilize if it chooses to do so.
