An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP segments. If the Maximum Segment Size (MSS) of a TCP connection was set to low values, such as 48 bytes, it can leave as little as 8 bytes for the user data, which significantly increases the Linux kernel's resource (CPU, Memory, and Bandwidth) utilization. A remote attacker could use this flaw to cause a denial of service (DoS) by repeatedly sending network traffic on a TCP connection with low TCP MSS.
It was found that the cgroup limitation of system resources used by Kubernetes can be bypassed. A guest pod can be used to consume a large amount of system memory.

docorenote in readelf.c in libmagic.a in file 5.35 has an out-of-bounds read because memcpy is misused.
A flaw was found in microprocessor execution engine sharing on SMT (e.g. Hyper-Threading) architectures. An attacker running a malicious process on the same core of the processor as the victim process, can extract certain secret information.
The reporter is able to steal an OpenSSL (<= 1.1.0h) P-384 private key from a TLS server using this new side-channel vector. It is a local attack in the sense that the malicious process must be running on the same physical core as the victim (an openSSL-powered TLS server in this case). But in general any application which branches on a secret value may be affected.

In FFmpeg 3.2 and 4.1, a denial of service in the subtitle decoder allows attackers to hog the CPU via a crafted video file in Matroska format, because ffhtmlmarkuptoass in libavcodec/htmlsubtitles.c has a complex format argument to sscanf.

A flaw was found in the Linux kernel vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS).

kernel/bpf/verifier.c in the Linux kernel before 4.20.6 performs undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize, leading to side-channel attacks.
An issue was discovered in LibVNCServer before 0.9.13. libvncserver/rre.c allows out-of-bounds access via encodings.
An issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an uninitialized read in exifprocessIFDinMAKERNOTE because of mishandling the makernote->offset relationship to valuelen.

Exiv2 through 0.27.1 allows an attacker to cause a denial of service (crash due to assertion failure) via an invalid data location in a CRW image file.
An HTTP detection flaw was discovered in Django. If deployed behind a reverse-proxy connecting to Django via HTTPS, django.http.HttpRequest.scheme() incorrectly detected client requests made using HTTP as using HTTPS. This resulted in incorrect results for issecure() and buildabsoluteuri(), and HTTP requests were not correctly redirected to HTTPS in accordance with SECURESSLREDIRECT.
An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles file ownership because setfsuid is not used.
FreeRDP prior to version 2.0.0-rc4 contains several Out-Of-Bounds Reads in the NTLM Authentication module that results in a Denial of Service (segfault).
A use-after-free vulnerability was discovered in the pngimagefree function in the libpng library. This could lead to denial of service or a potentially exploitable crash when a malformed image is processed.
An issue was discovered in LibVNCServer before 0.9.13. libvncserver/hextile.c allows out-of-bounds access via encodings.
Django 1.11.x before 1.11.19, 2.0.x before 2.0.11, and 2.1.x before 2.1.6 allows Uncontrolled Memory Consumption via a malicious attacker-supplied value to the django.utils.numberformat.format() function.
A flaw was found in the BigDecimal implementation in the Libraries component of OpenJDK. An untrusted numeric value parsed by a Java application could the application to use an excessive amount of CPU time.
A flaw was found in the RMI registry implementation in the RMI component of OpenJDK. Incorrect handling of the server-side dispatch could lead to selection of an incorrect skeleton class.
An issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an Invalid Read in exifprocessSOFn.
Fixed bug (Heap-buffer-overflow in estrndup via exifprocessIFDTAG) (CVE-2019-11036).
An issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an uninitialized read in exifprocessIFDinTIFF.
In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the GSS-API dissector could crash. This was addressed in epan/dissectors/packet-gssapi.c by ensuring that a valid dissector is called.
ImageMagick could allow a remote attacker to obtain sensitive information, caused by memory leaks in DecodeImage in coders/pcd.c. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to obtain sensitive information.
Irssi 1.1.x before 1.1.2 has a use after free when hidden lines are expired from the scroll buffer.
An issue was discovered in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. Due to the way rename() across filesystems is implemented, it is possible that file being renamed is briefly available with wrong permissions while the rename is ongoing, thus enabling unauthorized users to access the data.
An issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an uninitialized read in exifprocessIFDinMAKERNOTE because of mishandling the datalen variable.
