net-snmp: NULL pointer exception in _set_key in agent/helpers/table_container.c resulting in a denial of service

_set_key in agent/helpers/table_container.c in Net-SNMP before 5.8 has a NULL Pointer Exception bug that can be used by an authenticated attacker to remotely cause the instance to crash via a crafted UDP packet, resulting in Denial of Service.

ImageMagick: heap-based buffer over-read in the EncodeImage function of coders/pict.c

In ImageMagick 7.0.8-13 Q16, there is a heap-based buffer over-read in the EncodeImage function of coders/pict.c, which allows attackers to cause a denial of service via a crafted SVG image file.

kernel: Privilege escalation on arm64 via KVM hypervisor

arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVM_SET_ON_REG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control (with full register control). An attacker can also cause a denial of service (hypervisor panic) via an illegal exception return. This occurs because of insufficient restrictions on userspace access to the core register file, and because PSTATE.M validation does not prevent unintended execution modes.

kernel: Unprivileged users able to inspect kernel stacks of arbitrary tasks

An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents.

QEMU: net: ignore packets with large size

qemu_deliver_packet_iov in net/net.c in Qemu accepts packet sizes greater than INT_MAX, which allows attackers to cause a denial of service or possibly have unspecified other impact.

QEMU: pcnet: integer overflow leads to buffer overflow

Qemu has a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used.

ghostscript: Saved execution stacks can leak operator arrays (incomplete fix for CVE-2018-17183)

Artifex Ghostscript 9.25 and earlier allows attackers to bypass a sandbox protection mechanism via vectors involving errorhandler setup. NOTE: this issue exists because of an incomplete fix for CVE-2018-17183.

gpsd versions 2.90 to 3.17 and microjson versions 1.0 to 1.3, an open source project, allow a stack-based buffer overflow, which may allow remote attackers to execute arbitrary code on embedded platforms via traffic on Port 2947/TCP or crafted JSON inputs.

exiv2: Stack overflow in CiffDirectory::readDirectory() at crwimage_int.cpp leading to denial of service

CiffDirectory::readDirectory() at crwimage_int.cpp in Exiv2 0.26 has excessive stack consumption due to a recursive function, leading to Denial of service.

strongswan: heap buffer overflow using crafted certificates

The gmp plugin in strongSwan before 5.7.1 has a Buffer Overflow via a crafted certificate.

chromium-browser: Use after frees in PDFium

Incorrect object lifecycle handling in PDFium in Google Chrome prior to 71.0.3578.98 allowed a remote attacker to potentially exploit heap corruption via a crafted PDF file.

chromium-browser: UI spoof in Extensions

Incorrect dialog placement in Extensions in Google Chrome prior to 70.0.3538.67 allowed a remote attacker to spoof the contents of extension popups via a crafted HTML page.

chromium-browser: Security UI occlusion in full screen mode

Incorrect dialog placement in Cast UI in Google Chrome prior to 70.0.3538.67 allowed a remote attacker to obscure the full screen warning via a crafted HTML page.

chromium-browser: URL spoof in Omnibox

Incorrect handling of history on iOS in Navigation in Google Chrome prior to 70.0.3538.67 allowed a remote attacker to spoof the contents of the Omnibox (URL bar) via a crafted HTML page.

chromium-browser: Use after free in Blink

Use after free in HTMLImportsController in Blink in Google Chrome prior to 70.0.3538.67 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

chromium-browser: URL spoof in Omnibox

Incorrect handling of confusable characters in Omnibox in Google Chrome prior to 70.0.3538.67 allowed a remote attacker to spoof the contents of the Omnibox (URL bar) via a crafted domain name.

chromium-browser: iframe sandbox escape on iOS

Incorrect handling of googlechrome:// URL scheme on iOS in Intents in Google Chrome prior to 70.0.3538.67 allowed a remote attacker to escape the <iframe> sandbox via a crafted HTML page.

chromium-browser: Security UI occlusion in full screen mode

Incorrect dialog placement in WebContents in Google Chrome prior to 70.0.3538.67 allowed a remote attacker to obscure the full screen warning via a crafted HTML page.

chromium-browser: Memory corruption in GPU Internals

A heap buffer overflow in GPU in Google Chrome prior to 70.0.3538.67 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page.

chromium-browser: Heap buffer overflow in PDFium

Incorrect handling of PDF filter chains in PDFium in Google Chrome prior to 70.0.3538.67 allowed a remote attacker to perform an out of bounds memory read via a crafted PDF file.
