In FreeBSD 12.1-STABLE before r356035, 12.1-RELEASE before 12.1-RELEASE-p4, 11.3-STABLE before r356036, and 11.3-RELEASE before 11.3-RELEASE-p8, incomplete packet data validation may result in memory access after it has been freed leading to a kernel panic or other unpredictable results.

ruby: NUL injection vulnerability of File.fnmatch and File.fnmatch?

Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 mishandles path checking within File.fnmatch functions.

Irssi: use-after-free if the IRC server sends double CAP

Irssi 1.2.x before 1.2.2 has a use-after-free if the IRC server sends a double CAP.

An issue was discovered in the libflate crate before 0.1.25 for Rust. MultiDecoder::read has a use-after-free, leading to arbitrary code execution.

An issue was discovered in the smallvec crate before 0.6.10 for Rust. There is a double free for certain grow attempts with the current capacity.

kernel: double free in drivers/net/wireless/rsi/rsi_91x_usb.c via crafted USB device

drivers/net/wireless/rsi/rsi_91x_usb.c in the Linux kernel through 5.2.9 has a Double Free via crafted USB device traffic (which may be remote via usbip or usbredir).

kernel: Use-after-free in atalk_proc_exit function in net/appletalk

An issue was discovered in the Linux kernel before 5.0.9. There is a use-after-free in atalk_proc_exit, related to net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and net/appletalk/sysctl_net_atalk.c.

kernel: local attacker can trigger multiple use-after-free conditions results in privilege escalation

In the Linux kernel, a certain net/ipv4/tcp_output.c change, which was properly incorporated into 4.16.12, was incorrectly backported to the earlier longterm kernels, introducing a new vulnerability that was potentially more severe than the issue that was intended to be fixed by backporting. Specifically, by adding to a write queue between disconnection and re-connection, a local attacker can trigger multiple use-after-free conditions. This can result in a kernel crash, or potentially in privilege escalation. NOTE: this affects (for example) Linux distributions that use 4.9.x longterm kernels before 4.9.190 or 4.14.x longterm kernels before 4.14.139.

Live555 before 2019.08.16 has a Use-After-Free because GenericMediaServer::createNewClientSessionWithId can generate the same client session ID in succession, which is mishandled by the MPEG1or2 and Matroska file demultiplexors.

kernel: Use-after-free in drivers/net/wireless/intersil/p54/p54usb.c

An issue was discovered in the Linux kernel before 5.2.1. There is a use-after-free caused by a malicious USB device in the drivers/net/wireless/intersil/p54/p54usb.c driver.

kernel: use after free in drivers/media/usb/cpia2/cpia2_usb.c driver

An issue was discovered in the Linux kernel before 5.2.6. There is a use-after-free caused by a malicious USB device in the drivers/media/usb/cpia2/cpia2_usb.c driver.

kernel: use-after-free in sound/core/init.c and sound/core/info.c

An issue was discovered in the Linux kernel before 5.0.10. There is a use-after-free in the sound subsystem because card disconnection causes certain data structures to be deleted too early. This is related to sound/core/init.c and sound/core/info.c.

kernel: double-free caused by malicious USB device in drivers/usb/misc/rio500.c

An issue was discovered in the Linux kernel before 5.1.8. There is a double-free caused by a malicious USB device in the drivers/usb/misc/rio500.c driver.

kernel: use-after-free in drivers/media/v4l2-core/v4l2-dev.c

An issue was discovered in the Linux kernel before 5.2.6. There is a use-after-free caused by a malicious USB device in the drivers/media/v4l2-core/v4l2-dev.c driver because drivers/media/radio/radio-raremono.c does not properly allocate memory.

AdPlug 2.3.1 has a double free in the Cu6mPlayer class in u6m.h.

ImageMagick: Use after free in ReadMATImage in coders/mat.c

coders/mat.c in ImageMagick 7.0.8-43 Q16 allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly have unspecified other impact by crafting a Matlab image file that is mishandled in ReadImage in MagickCore/constitute.c.

ImageMagick: use-after-free in magick/blob.c resulting in a denial of service

In ImageMagick 7.x before 7.0.8-42 and 6.x before 6.9.10-42, there is a use after free vulnerability in the UnmapBlob function that allows an attacker to cause a denial of service by sending a crafted file.

A use-after-free flaw in the sandbox container implemented in cmdguard.sys in Comodo Antivirus 12.0.0.6870 can be triggered due to a race condition when handling IRP_MJ_CLEANUP requests in the minifilter for directory change notifications. This allows an attacker to cause a denial of service (BSOD) when an executable is run inside the container.

edk2: double-unmap issue in SdMmcCreateTrb function in MdeModulePkg/Bus/Pci/SdMmcPciHcDxe/SdMmcPciHci.c

Logic issue EDK II may allow an unauthenticated user to potentially enable denial of service via adjacent access.

edk2: potential use-after-free due to the original configuration runtime memory is freed but it is still exposed to the OS runtime

Use after free vulnerability in EDK II may allow an authenticated user to potentially enable escalation of privilege, information disclosure and/or denial of service via adjacent access.
