1 CVE-2020-35480 200 +Info 2020-12-18 2021-07-21
5.0
None Remote Low Not required Partial None None
An issue was discovered in MediaWiki before 1.35.1. Missing users (accounts that don't exist) and hidden users (accounts that have been explicitly hidden due to being abusive, or similar) that the viewer cannot see are handled differently, exposing sensitive information about the hidden status to unprivileged viewers. This exists on various code paths.
2 CVE-2020-29569 252 +Info 2020-12-15 2021-07-21
7.2
None Local Low Not required Complete Complete Complete
An issue was discovered in the Linux kernel through 5.10.1, as used with Xen through 4.14.x. The Linux kernel PV block backend expects the kernel thread handler to reset ring->xenblkd to NULL when stopped. However, the handler may not have time to run if the frontend quickly toggles between the states connect and disconnect. As a consequence, the block backend may re-use a pointer after it was freed. A misbehaving guest can trigger a dom0 crash by continuously connecting / disconnecting a block frontend. Privilege escalation and information leaks cannot be ruled out. This only affects systems with a Linux blkback.
3 CVE-2020-27825 362 DoS +Info 2020-12-11 2021-05-21
5.4
None Local Medium Not required Partial None Complete
A use-after-free flaw was found in kernel/trace/ring_buffer.c in Linux kernel (before 5.10-rc1). There was a race problem in trace_open and resize of cpu buffer running parallely on different cpus, may cause a denial of service problem (DOS). This flaw could even allow a local attacker with special user privilege to a kernel information leak threat.
4 CVE-2020-25653 362 DoS +Info 2020-11-26 2021-10-19
5.4
None Local Medium Not required Partial None Complete
A race condition vulnerability was found in the way the spice-vdagentd daemon handled new client connections. This flaw may allow an unprivileged local guest user to become the active agent for spice-vdagentd, possibly resulting in a denial of service or information leakage from the host. The highest threat from this vulnerability is to data confidentiality as well as system availability. This flaw affects spice-vdagent versions 0.20 and prior.
5 CVE-2020-25651 200 DoS +Info 2020-11-26 2021-10-19
3.3
None Local Medium Not required Partial None Partial
A flaw was found in the SPICE file transfer protocol. File data from the host system can end up in full or in parts in the client connection of an illegitimate local user in the VM system. Active file transfers from other users could also be interrupted, resulting in a denial of service. The highest threat from this vulnerability is to data confidentiality as well as system availability. This flaw affects spice-vdagent versions 0.20 and prior.
6 CVE-2020-17527 200 +Info 2020-12-03 2021-09-14
5.0
None Remote Low Not required Partial None None
While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests.
7 CVE-2020-16166 200 +Info 2020-07-30 2021-07-21
4.3
None Remote Medium Not required Partial None None
The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c.
8 CVE-2020-15005 200 +Info 2020-06-24 2021-07-21
2.6
None Remote High Not required Partial None None
In MediaWiki before 1.31.8, 1.32.x and 1.33.x before 1.33.4, and 1.34.x before 1.34.2, private wikis behind a caching server using the img_auth.php image authorization security feature may have had their files cached publicly, so any unauthorized user could view them. This occurs because Cache-Control and Vary headers were mishandled.
9 CVE-2020-10756 125 +Info 2020-07-09 2021-08-04
2.1
None Local Low Not required Partial None None
An out-of-bounds read vulnerability was found in the SLiRP networking implementation of the QEMU emulator. This flaw occurs in the icmp6_send_echoreply() routine while replying to an ICMP echo request, also known as ping. This flaw allows a malicious guest to leak the contents of the host memory, resulting in possible information disclosure. This flaw affects versions of libslirp before 4.3.1.
10 CVE-2020-9497 200 +Info 2020-07-02 2021-07-21
1.2
None Local High Not required Partial None None
Apache Guacamole 1.1.0 and older do not properly validate datareceived from RDP servers via static virtual channels. If a userconnects to a malicious or compromised RDP server, specially-craftedPDUs could result in disclosure of information within the memory ofthe guacd process handling the connection.
11 CVE-2020-8164 502 +Info 2020-06-19 2020-09-30
5.0
None Remote Low Not required Partial None None
A deserialization of untrusted data vulnerability exists in rails < 5.2.4.3, rails < 6.0.3.1 which can allow an attacker to supply information can be inadvertently leaked fromStrong Parameters.
12 CVE-2020-6489 200 +Info 2020-05-21 2021-01-27
4.3
None Remote Medium Not required Partial None None
Inappropriate implementation in developer tools in Google Chrome prior to 83.0.4103.61 allowed a remote attacker who had convinced the user to take certain actions in developer tools to obtain potentially sensitive information from disk via a crafted HTML page.
13 CVE-2020-6473 200 +Info 2020-05-21 2021-07-21
4.3
None Remote Medium Not required Partial None None
Insufficient policy enforcement in Blink in Google Chrome prior to 83.0.4103.61 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page.
14 CVE-2020-6472 200 +Info 2020-05-21 2021-07-21
4.3
None Remote Medium Not required Partial None None
Insufficient policy enforcement in developer tools in Google Chrome prior to 83.0.4103.61 allowed an attacker who convinced a user to install a malicious extension to obtain potentially sensitive information from process memory or disk via a crafted Chrome Extension.
15 CVE-2020-6061 787 +Info 2020-02-19 2022-01-28
7.5
None Remote Low Not required Partial Partial Partial
An exploitable heap out-of-bounds read vulnerability exists in the way CoTURN 4.5.1.1 web server parses POST requests. A specially crafted HTTP POST request can lead to information leaks and other misbehavior. An attacker needs to send an HTTPS request to trigger this vulnerability.
16 CVE-2020-5202 +Info 2020-01-21 2022-01-01
2.1
None Local Low Not required Partial None None
apt-cacher-ng through 3.3 allows local users to obtain sensitive information by hijacking the hardcoded TCP port. The /usr/lib/apt-cacher-ng/acngtool program attempts to connect to apt-cacher-ng via TCP on localhost port 3142, even if the explicit SocketPath=/var/run/apt-cacher-ng/socket command-line option is passed. The cron job /etc/cron.daily/apt-cacher-ng (which is active by default) attempts this periodically. Because 3142 is an unprivileged port, any local user can try to bind to this port and will receive requests from acngtool. There can be sensitive data in these requests, e.g., if AdminAuth is enabled in /etc/apt-cacher-ng/security.conf. This sensitive data can leak to unprivileged local users that manage to bind to this port before the apt-cacher-ng daemon can.
17 CVE-2020-4067 665 +Info 2020-06-29 2020-07-09
5.0
None Remote Low Not required Partial None None
In coturn before version 4.5.1.3, there is an issue whereby STUN/TURN response buffer is not initialized properly. There is a leak of information between different client connections. One client (an attacker) could use their connection to intelligently query coturn to get interesting bytes in the padding bytes from the connection of another client. This has been fixed in 4.5.1.3.
18 CVE-2020-3812 200 +Info 2020-05-26 2021-07-21
2.1
None Local Low Not required Partial None None
qmail-verify as used in netqmail 1.06 is prone to an information disclosure vulnerability. A local attacker can test for the existence of files and directories anywhere in the filesystem because qmail-verify runs as root and tests for the existence of files in the attacker's home directory, without dropping its privileges first.
19 CVE-2012-0844 200 +Info 2020-02-21 2020-02-24
2.1
None Local Low Not required Partial None None
Information-disclosure vulnerability in Netsurf through 2.8 due to a world-readable cookie jar.
20 CVE-2011-4915 200 +Info 2020-02-20 2020-02-25
2.1
None Local Low Not required Partial None None
fs/proc/base.c in the Linux kernel through 3.1 allows local users to obtain sensitive keystroke information via access to /proc/interrupts.
