An issue was discovered in Ivanti Workspace Control before 10.3.10.0 and RES One Workspace. A local authenticated user can bypass Application Whitelisting restrictions to execute arbitrary code by leveraging multiple unspecified attack vectors.

On Telus Actiontec WEB6000Q v1.1.02.22 devices, an attacker can login with root level access with the user "root" and password "admin" by using the enabled onboard UART headers.

xen: oxenstored does not apply quota-maxentity (XSA-272)

An issue was discovered in Xen through 4.11.x. The logic in oxenstored for handling writes depended on the order of evaluation of expressions making up a tuple. As indicated in section 7.7.3 "Operations on data structures" of the OCaml manual, the order of evaluation of subexpressions is not specified. In practice, different implementations behave differently. Thus, oxenstored may not enforce the configured quota-maxentity. This allows a malicious or buggy guest to write as many xenstore entries as it wishes, causing unbounded memory usage in oxenstored. This can lead to a system-wide DoS.

xen: Use of v2 grant tables may cause crash on ARM (XSA-268)

An issue was discovered in Xen through 4.11.x. ARM never properly implemented grant table v2, either in the hypervisor or in Linux. Unfortunately, an ARM guest can still request v2 grant tables; they will simply not be properly set up, resulting in subsequent grant-related hypercalls hitting BUG() checks. An unprivileged guest can cause a BUG() check in the hypervisor, resulting in a denial-of-service (crash).

xen: x86 Incorrect MSR_DEBUGCTL handling lets guests enable BTS (XSA-269)

An issue was discovered in Xen through 4.11.x. The DEBUGCTL MSR contains several debugging features, some of which virtualise cleanly, but some do not. In particular, Branch Trace Store is not virtualised by the processor, and software has to be careful to configure it suitably not to lock up the core. As a result, it must only be available to fully trusted guests. Unfortunately, in the case that vPMU is disabled, all value checking was skipped, allowing the guest to choose any MSR_DEBUGCTL setting it likes. A malicious or buggy guest administrator (on Intel x86 HVM or PVH) can lock up the entire host, causing a Denial of Service.

php: Mishandled http_header_value in an atoi() call in http_fopen_wrapper.c

An issue was discovered in PHP 7.0.x before 7.0.27, 7.1.x before 7.1.13, and 7.2.x before 7.2.1. Inappropriately parsing an HTTP response leads to a segmentation fault because http_header_value in ext/standard/http_fopen_wrapper.c can be a NULL value that is mishandled in an atoi call.

xen: Uninitialized state in x86 PV failsafe callback path (XSA-274)

An issue was discovered in the Linux kernel through 4.17.11, as used in Xen through 4.11.x. The xen_failsafe_callback entry point in arch/x86/entry/entry_64.S does not properly maintain RBX, which allows local users to cause a denial of service (uninitialized memory usage and system crash). Within Xen, 64-bit x86 PV Linux guest OS users can trigger a guest OS crash or possibly gain privileges.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 9.0.1.1049. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of FlateDecode streams. The issue results from the lack of proper initialization of a pointer prior to accessing it. An attacker can leverage this vulnerability to execute code under the context of the current process. Was ZDI-CAN-5763.

Improper memory initialization in Platform Sample/Silicon Reference firmware Intel(R) Server Board, Intel(R) Server System and Intel(R) Compute Module may allow privileged user to potentially enable an escalation of privilege via local access.

Failure to initialize the extra buffer can lead to an out of buffer access in WLAN function in Snapdragon Auto, Snapdragon Compute, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile in MDM9150, MDM9206, MDM9607, MDM9640, MDM9650, MSM8996AU, QCS605, SD 425, SD 427, SD 430, SD 435, SD 450, SD 625, SD 636, SD 712 / SD 710 / SD 670, SD 820A, SD 835, SD 845 / SD 850, SD 855, SDA660, SDM630, SDM660, SDX20, SDX24

In all android releases(Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, while processing fastboot flash command, memory leak or unexpected behavior may occur due to processing of unintialized data buffers.

kernel: coresight: kernel panic caused by invalid CPU

The etm_setup_aux function in drivers/hwtracing/coresight/coresight-etm-perf.c in the Linux kernel before 4.10.2 allows attackers to cause a denial of service (panic) because a parameter is incorrectly used as a local variable.

postgresql: Certain host connection parameters defeat client-side security defenses

A vulnerability was found in libpq, the default PostgreSQL client library where libpq failed to properly reset its internal state between connections. If an affected version of libpq was used with "host" or "hostaddr" connection parameters from untrusted input, attackers could bypass client-side connection security features, obtain access to higher privileged connections or potentially cause other impact through SQL injection, by causing the PQescape() functions to malfunction. Postgresql versions before 10.5, 9.6.10, 9.5.14, 9.4.19, and 9.3.24 are affected.

kernel: kvm: vmx: host GDT limit corruption

A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cpu variables. An attacker can use this to escalate their privileges.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 9.0.0.29935. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of U3D Node objects. The issue results from the lack of proper initialization of a pointer prior to accessing it. An attacker can leverage this vulnerability to execute code under the context of the current process. Was ZDI-CAN-5411.

An issue was discovered in KTextEditor 5.34.0 through 5.45.0. Insecure handling of temporary files in the KTextEditor's kauth_ktexteditor_helper service (as utilized in the Kate text editor) can allow other unprivileged users on the local system to gain root privileges. The attack occurs when one user (who has an unprivileged account but is also able to authenticate as root) writes a text file using Kate into a directory owned by a another unprivileged user. The latter unprivileged user conducts a symlink attack to achieve privilege escalation.

p7zip: unitialized memory due to incorrect logic of RAR decoder might lead to arbitrary code execution

Incorrect initialization logic of RAR decoder objects in 7-Zip 18.03 and before can lead to usage of uninitialized memory, allowing remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive.

memcached: Integer Overflow in items.c:item_free()

memcached version prior to 1.4.37 contains an Integer Overflow vulnerability in items.c:item_free() that can result in data corruption and deadlocks due to items existing in hash table being reused from free list. This attack appear to be exploitable via network connectivity to the memcached service. This vulnerability appears to have been fixed in 1.4.37 and later.
