A vulnerability was found in Python 2.7.x through 2.7.16 and 3.x through 3.7.2. An improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization could lead to an Information Disclosure (credentials, cookies, etc. that are cached against a given hostname) in the urllib.parse.urlsplit, urllib.parse.urlparse components. A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly.

FreeRDP prior to version 2.0.0-rc4 contains an Integer Truncation that leads to a Heap-Based Buffer Overflow in function updatereadbitmapupdate() and results in a memory corruption and probably even a remote code execution.
An issue was discovered in libX11 through 1.6.5. Functions GetFPath.c:XGetFontPath, ListExt.c:XListExtensions and FontNames.c:XListFonts are vulnerable to an off-by-one error when parsing list of strings returned by malicious server responses, leading to DoS.

A malicious server could send a specially crafted packet which could result in an unchecked integer overflow. The value would then be used to allocate memory causing a possible memory write out of bounds error.
Fixed bug (Heap-buffer-overflow in estrndup via exifprocessIFDTAG) (CVE-2019-11036).
An out of bounds read flaw was discovered in libssh2 before 1.8.1 in the libssh2packetrequire and libssh2packetrequirev functions. A remote attacker who compromises a SSH server may be able to cause a Denial of Service or read data in the client memory.
A flaw was found in pacemaker. Insufficient verification of client-side authentication combined with other IPC weaknesses leads to local privilege escalation.

In Pallets Jinja before 2.10.1, str.formatmap allows a sandbox escape.
The sandbox is used to restrict what code can be evaluated when rendering untrusted, user-provided templates. Due to the way string formatting works in Python, the str.formatmap method could be used to escape the sandbox.
This issue was previously addressed for the str.format method in Jinja 2.8.1, which discusses the issue in detail. However, the less-common str.formatmap method was overlooked. This release applies the same sandboxing to both methods.
If you cannot upgrade Jinja, you can override the issafeattribute method on the sandbox and explicitly disallow the formatmap method on string objects.
embed/ephy-web-view.c in GNOME Web (aka Epiphany) through 3.31.4 allows address bar spoofing because a page load triggered by JavaScript leads to updating an address as if it were triggered by a safer visit type (e.g., VISITLINK, VISITTYPED, VISITBOOKMARK, or VISITHOMEPAGE).

Apache HTTP Server, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute code with the privileges of the parent process (usually root) by manipulating the scoreboard.
A use after free issue was found in the way Linux kernel's KVM hypervisor emulates a preemption timer for L2 guest when nested(=1) virtualization is enabled. This high resolution timer(hrtimer) runs when L2 guest is active. After VM exit, in syncvmcs12() timer object is stopped. The use-after-free occurs if the timer object is free'd before calling syncvmcs12() routine.
A guest user/process could use this flaw to crash the host kernel resulting in DoS OR potentially gain privileged access to a system.
It affects only Intel processors and only when nested virtualization is enabled.

In Poppler 0.73.0, a heap-based buffer over-read (due to an integer signedness error in the XRef::getEntry function in XRef.cc) allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document, as demonstrated by pdftocairo.
In Artifex Ghostscript through 9.26, ephemeral or transient procedures can allow access to system operators, leading to remote code execution.
aria2c in aria2 1.33.1, when --log is used, can store an HTTP Basic Authentication username and password in a file, which might allow local users to obtain sensitive information by reading this file.
An infinite loop issue was found in the vhostnet kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handlerx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhostnet kernel thread, resulting in a DoS scenario.
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 race condition was found in modauthdigest when the web server was running in a threaded MPM configuration. It could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions.

Catastrophic backtracking vulnerability was found in Python. Exploitation of a regular expression in difflib.ISLINEJUNK method in servers that use difflib can lead to denial of service.

Catastrophic backtracking vulnerability was found in Python. Exploitation of a regular expression in pop3lib's apop() method although limited by 2048 chars, can lead to denial of service.

It was discovered in gnutls before version 3.6.7 upstream that there is an uninitialized pointer access in gnutls versions 3.6.3 or later which can be triggered by certain post-handshake messages.
An issue was discovered in ListExt.c:XListExtensions and GetFPath.c:XGetFontPath in libX11 through version 1.6.5. A malicious server can send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed later on, leading to DoS (segmentation fault).
