xen: x86: infinite loop due to missing PoD error checking (XSA-246)

An issue was discovered in Xen through 4.9.x allowing HVM guest OS users to cause a denial of service (infinite loop and host OS hang) by leveraging the mishandling of Populate on Demand (PoD) errors.

kernel: ACPI operand cache leak in acpi_ns_terminate()

The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel before 4.12 does not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.

A remote code execution vulnerability in the Android media framework (libstagefright). Product: Android. Versions: 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2. Android ID: A-37237396.

A remote code execution vulnerability in the Android media framework (libstagefright). Product: Android. Versions: 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2. Android ID: A-36715268.

An elevation of privilege vulnerability in the Goodix touchscreen driver could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as High because it first requires compromising a privileged process. Product: Android. Versions: Kernel-3.10. Android ID: A-32749036. References: QC-CR#1098602.

Kernel: KVM: DoS via write flood to I/O port 0x80

The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic.

A vulnerability in the web management interface of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a missing internal handler for the specific request. An attacker could exploit this vulnerability by accessing a specific hidden URL on the GUI web management interface. A successful exploit could allow the attacker to cause a reload of the device, resulting in a DoS condition. This vulnerability affects only the Cisco Wireless LAN Controller 8.3.102.0 release. Cisco Bug IDs: CSCvb48198.

ImageMagick: Improper validation of short files in coders/png.c

In ImageMagick before 6.9.9-0 and 7.x before 7.0.6-1, a crafted PNG file could trigger a crash because there was an insufficient check for short files.

The ReadJPEGImage function in coders/jpeg.c in GraphicsMagick 1.3.26 creates a pixel cache before a successful read of a scanline, which allows remote attackers to cause a denial of service (resource consumption) via crafted JPEG files.

php: Incorrect return value check of OpenSSL sealing function leads to crash

In PHP before 5.6.31, 7.x before 7.0.21, and 7.1.x before 7.1.7, the openssl extension PEM sealing code did not check the return value of the OpenSSL sealing function, which could lead to a crash of the PHP interpreter, related to an interpretation conflict for a negative number in ext/openssl/openssl.c, and an OpenSSL documentation omission.

The private_address_check ruby gem before 0.4.0 is vulnerable to a bypass due to use of Ruby's Resolv.getaddresses method, which is OS-dependent and should not be relied upon for security measures, such as when used to blacklist private network addresses to prevent server-side request forgery.

A vulnerability in SMART-SSL Accelerator functionality for Cisco Wide Area Application Services (WAAS) 6.2.1, 6.2.1a, and 6.2.3a could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition where the WAN optimization could stop functioning while the process restarts. The vulnerability is due to a Secure Sockets Layer/Transport Layer Security (SSL/TLS) alert being incorrectly handled when in a specific SSL/TLS connection state. An attacker could exploit this vulnerability by establishing a SMART-SSL connection through the targeted device. The attacker would then send a crafted stream of SSL/TLS traffic. An exploit could allow the attacker to cause a DoS condition where WAN optimization could stop processing traffic for a short period of time. Cisco Bug IDs: CSCvb71133.

A vulnerability in the ingress UDP packet processing functionality of Cisco Virtualized Packet Core-Distributed Instance (VPC-DI) Software 19.2 through 21.0 could allow an unauthenticated, remote attacker to cause both control function (CF) instances on an affected system to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient handling of user-supplied data by the affected software. An attacker could exploit this vulnerability by sending crafted UDP packets to the distributed instance (DI) network addresses of both CF instances on an affected system. A successful exploit could allow the attacker to cause an unhandled error condition on the affected system, which would cause the CF instances to reload and consequently cause the entire VPC to reload, resulting in the disconnection of all subscribers and a DoS condition on the affected system. This vulnerability can be exploited via IPv4 traffic only. Cisco Bug IDs: CSCvc01665 CSCvc35565.

StreamRelay.NET.exe ver2.14.0.7 and earlier allows remote attackers to cause a denial of service via unspecified vectors.

Windows Hyper-V in Microsoft Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT 8.1, Windows 10 Gold, 1511, 1607, 1703, and Windows Server 2016 allows an attacker to gain elevated privileges on a target guest operating system when Windows Hyper-V instruction emulation fails to properly enforce privilege levels, aka "Hypervisor Code Integrity Elevation of Privilege Vulnerability".

Improper checks for unusual or exceptional conditions in Brocade NetIron 05.8.00 and later releases up to and including 06.1.00, when the Management Module is continuously scanned on port 22, may allow attackers to cause a denial of service (crash and reload) of the management module.

Revive Adserver before 3.2.5 and 4.0.0 suffers from Special Element Injection. Usernames weren't properly sanitised when creating users on a Revive Adserver instance. Especially, control characters were not filtered, allowing apparently identical usernames to co-exist in the system, due to the fact that such characters are normally ignored when an HTML page is displayed in a browser. The issue could have therefore been exploited for user spoofing, although elevated privileges are required to create users within Revive Adserver.

fedora-arm-installer up to and including 1.99.16 is vulnerable to local privilege escalation due to lack of checking the error condition of mount operation failure on unsafely created temporary directories.

sDNSProxy.exe ver1.1.0.0 and earlier allows remote attackers to cause a denial of service via unspecified vectors.
