gd: Heap-based buffer overflow in gdImageColorMatch() in gd_color_match.c

gdImageColorMatch in gd_color_match.c in the GD Graphics Library (aka LibGD) 2.2.5, as used in the imagecolormatch function in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1, has a heap-based buffer overflow. This can be exploited by an attacker who is able to trigger imagecolormatch calls with crafted image data.

Kernel: KVM: potential use-after-free via kvm_ioctl_create_device()

In the Linux kernel before 4.20.8, kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandles reference counting because of a race condition, leading to a use-after-free.

QEMU: slirp: heap buffer overflow in tcp_emu()

In QEMU 3.0.0, tcp_emu in slirp/tcp_subr.c has a heap-based buffer overflow.

lua: use-after-free in lua_upvaluejoin in lapi.c resulting in denial of service

Lua 5.3.5 has a use-after-free in lua_upvaluejoin in lapi.c. For example, a crash outcome might be achieved by an attacker who is able to trigger a debug.upvaluejoin call in which the arguments have certain relationships.

On version 1.9.0, If DEBUG logging is enable, F5 Container Ingress Service (CIS) for Kubernetes and Red Hat OpenShift (k8s-bigip-ctlr) log files may contain BIG-IP secrets such as SSL Private Keys and Private key Passphrases as provided as inputs by an AS3 Declaration.

QEMU: scsi-generic: possible OOB access while handling inquiry request

In QEMU 3.1, scsi_handle_inquiry_reply in hw/scsi/scsi-generic.c allows out-of-bounds write and read operations.

TCP-pipelined queries can bypass tcp-clients limit

With pipelining enabled each incoming query on a TCP connection requires a similar resource allocation to a query received via UDP or via TCP without pipelining enabled. A client using a TCP-pipelined connection to a server could consume more resources than the server has been provisioned to handle. When a TCP connection with a large number of pipelined queries is closed, the load on the server releasing these multiple resources can cause it to become unresponsive, even for queries that can be answered authoritatively or from cache. (This is most likely to be perceived as an intermittent server problem).

A race condition when discarding malformed packets can cause BIND to exit with an assertion failure

A race condition which may occur when discarding malformed packets can result in BIND exiting due to a REQUIRE assertion failure in dispatch.c. Versions affected: BIND 9.11.0 -> 9.11.7, 9.12.0 -> 9.12.4-P1, 9.14.0 -> 9.14.2. Also all releases of the BIND 9.13 development branch and version 9.15.0 of the BIND 9.15 development branch and BIND Supported Preview Edition versions 9.11.3-S1 -> 9.11.7-S1.

Zone transfer controls for writable DLZ zones were not effective

Controls for zone transfers may not be properly applied to Dynamically Loadable Zones (DLZs) if the zones are writable Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P2, 9.12.0 -> 9.12.3-P2, and versions 9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 -> 9.13.6 of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for vulnerability to CVE-2019-6465.

systemd: Insufficient input validation in bus_process_object() resulting in PID 1 crash

An issue was discovered in sd-bus in systemd 239. bus_process_object() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic).

webkitgtk: processing maliciously crafted web content lead to URI spoofing

WebKitGTK and WPE WebKit prior to version 2.24.1 are vulnerable to address bar spoofing upon certain JavaScript redirections. An attacker could cause malicious web content to be displayed as if for a trusted URI. This is similar to the CVE-2018-8383 issue in Microsoft Edge.

webkitgtk: Multiple memory corruption issues leading to arbitrary code execution

Multiple memory corruption issues were addressed with improved memory handling. This issue is fixed in iOS 12.3, macOS Mojave 10.14.5, tvOS 12.3, Safari 12.1.1, iTunes for Windows 12.9.5, iCloud for Windows 7.12. Processing maliciously crafted web content may lead to arbitrary code execution.

polkit: Temporary auth hijacking via PID reuse and non-atomic fork

In PolicyKit (aka polkit) 0.115, the "start time" protection mechanism can be bypassed because fork() is not atomic, and therefore authorization decisions are improperly cached. This is related to lack of uid checking in polkitbackend/polkitbackendinteractiveauthority.c.

ghostscript: subroutines within pseudo-operators must themselves be pseudo-operators (700317)

In Artifex Ghostscript through 9.26, ephemeral or transient procedures can allow access to system operators, leading to remote code execution.

wget: do_conversion() heap-based buffer overflow vulnerability

Buffer overflow in GNU Wget 1.20.1 and earlier allows remote attackers to cause a denial-of-service (DoS) or may execute an arbitrary code via unspecified vectors.

chromium-browser: Arbitrary read in SwiftShader

Out of bounds read in SwiftShader in Google Chrome prior to 77.0.3865.75 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page.

chromium-browser: SameSite cookie bypass

Insufficient policy enforcement in Blink in Google Chrome prior to 77.0.3865.75 allowed a remote attacker to leak cross-origin data via a crafted HTML page.

chromium-browser: Extensions can read some local files

Insufficient policy enforcement in extensions in Google Chrome prior to 77.0.3865.75 allowed an attacker who convinced a user to install a malicious extension to read local files via a crafted Chrome Extension.

chromium-browser: Use-after-free in V8

Use after free in V8 in Google Chrome prior to 77.0.3865.75 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

chromium-browser: Out-of-bounds access in V8

Out of bounds memory access in JavaScript in Google Chrome prior to 77.0.3865.75 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
