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.
yast2-users before 3.1.47, as used in SUSE Linux Enterprise 12 SP1, does not properly set empty password fields in /etc/shadow during an AutoYaST installation when the profile does not contain inst-sys users, which might allow attackers to have unspecified impact via unknown vectors.
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.
/ext/phar/pharobject.c in PHP 7.0.7 and 5.6.x allows remote attackers to execute arbitrary code. NOTE: Introduced as part of an incomplete fix to CVE-2015-6833.
A stack overflow vulnerability in the catopen function was found, causing applications which pass long strings to the catopen function to crash or, potentially execute arbitrary code.

distribute-cache.c in ImageMagick re-uses objects after they have been destroyed, which allows remote attackers to have unspecified impact via unspecified vectors.
ext/libxml/libxml.c in PHP before 5.5.22 and 5.6.x before 5.6.6, when PHP-FPM is used, does not isolate each thread from libxmldisableentityloader changes in other threads, which allows remote attackers to conduct XML External Entity (XXE) and XML Entity Expansion (XEE) attacks via a crafted XML document, a related issue to CVE-2015-5161.
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.
It was found that out-of-range time values passed to the strftime function may cause it to crash, leading to a denial of service, or potentially disclosure information.

Mercurial before 3.7.3 allows remote attackers to execute arbitrary code via a crafted name when converting a Git repository.
Mercurial before 3.7.3 allows remote attackers to execute arbitrary code via a crafted git ext:: URL when cloning a subrepository.
The binary delta decoder in Mercurial before 3.7.3 allows remote attackers to execute arbitrary code via a (1) clone, (2) push, or (3) pull command, related to (a) a list sizing rounding error and (b) short records.
named in ISC BIND 9.x before 9.9.8-P4 and 9.10.x before 9.10.3-P4 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted signature record for a DNAME record, related to db.c and resolver.c.
A stack-based buffer overflow was found in libresolv when invoked from nssdns, allowing specially crafted DNS responses to seize control of EIP in the DNS client.
The buffer overflow occurs in the functions senddg (send datagram) and sendvc (send TCP) for the NSS module libnssdns.so.2 when calling getaddrinfo with AFUNSPEC family, or in some cases AFINET6 family. The use of AFUNSPEC (or AFINET6 in some cases) triggers the low-level resolver code to send out two parallel queries for A and AAAA. A mismanagement of the buffers used for those queries could result in the response of a query writing beyond the alloca allocated buffer created by resnquery.
Multiple integer overflows in the (1) gettimetmax and (2) gettimetmin functions in archivereadsupportformatmtree.c in libarchive before 3.2.0 allow remote attackers to have unspecified impact via a crafted mtree file, which triggers undefined behavior.

FreeRADIUS 2.2.x before 2.2.8 and 3.0.x before 3.0.9 does not properly check revocation of intermediate CA certificates.
It was found that ntpd did not correctly implement the -g option:
-g Normally, ntpd exits with a message to the system log if the offset exceeds the panic threshold, which is 1000 s by default. This option allows the time to be set to any value without restriction; however, this can happen only once. If the thresh‐ old is exceeded after that, ntpd will exit with a message to the system log. This option can be used with the -q and -x options. See the tinker command for other options.
ntpd could actually step the clock multiple times by more than the panic threshold if its clock discipline doesn't have enough time to reach the sync state and stay there for at least one update. If a man-in-the-middle attacker can control the NTP traffic since ntpd was started (or maybe up to 15-30 minutes after that), they can prevent the client from reaching the sync state and force it to step its clock by any amount any number of times, which can be used by attackers to expire certificates, etc.
This is contrary to what the documentation says. Normally, the assumption is that an MITM attacker can step the clock more than the panic threshold only once when ntpd starts and to make a larger adjustment the attacker has to divide it into multiple smaller steps, each taking 15 minutes, which is slow.
bsdtar in libarchive before 3.2.0 allows remote attackers to cause a denial of service (infinite loop) via an ISO with a directory that is a member of itself.

The mysql-systemd-helper script in the mysql-community-server package before 5.6.28-2.17.1 in openSUSE 13.2 and before 5.6.28-13.1 in openSUSE Leap 42.1 and the mariadb package before 10.0.22-2.21.2 in openSUSE 13.2 and before 10.0.22-3.1 in SUSE Linux Enterprise (SLE) 12.1 and openSUSE Leap 42.1 allows local users to discover database credentials by listing a process and its arguments.
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.
