CVE-2021-28702 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2022-08-15 4.6 MEDIUM 7.6 HIGH
PCI devices with RMRRs not deassigned correctly Certain PCI devices in a system might be assigned Reserved Memory Regions (specified via Reserved Memory Region Reporting, "RMRR"). These are typically used for platform tasks such as legacy USB emulation. If such a device is passed through to a guest, then on guest shutdown the device is not properly deassigned. The IOMMU configuration for these devices which are not properly deassigned ends up pointing to a freed data structure, including the IO Pagetables. Subsequent DMA or interrupts from the device will have unpredictable behaviour, ranging from IOMMU faults to memory corruption.
CVE-2019-9511 12 Apache, Apple, Canonical and 9 more 22 Traffic Server, Mac Os X, Swiftnio and 19 more 2022-08-12 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2019-9513 12 Apache, Apple, Canonical and 9 more 22 Traffic Server, Mac Os X, Swiftnio and 19 more 2022-08-12 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU.
CVE-2019-9514 13 Apache, Apple, Canonical and 10 more 30 Traffic Server, Mac Os X, Swiftnio and 27 more 2022-08-12 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.
CVE-2019-9515 12 Apache, Apple, Canonical and 9 more 24 Traffic Server, Mac Os X, Swiftnio and 21 more 2022-08-12 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2019-9518 11 Apache, Apple, Canonical and 8 more 20 Traffic Server, Mac Os X, Swiftnio and 17 more 2022-08-12 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU.
CVE-2020-10531 9 Canonical, Debian, Fedoraproject and 6 more 11 Ubuntu Linux, Debian Linux, Fedora and 8 more 2022-08-12 6.8 MEDIUM 8.8 HIGH
An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1. An integer overflow, leading to a heap-based buffer overflow, exists in the UnicodeString::doAppend() function in common/unistr.cpp.
CVE-2021-44832 5 Apache, Cisco, Debian and 2 more 22 Log4j, Cloudcenter, Debian Linux and 19 more 2022-08-08 8.5 HIGH 6.6 MEDIUM
Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack when a configuration uses a JDBC Appender with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2.
CVE-2021-43859 4 Debian, Fedoraproject, Oracle and 1 more 10 Debian Linux, Fedora, Commerce Guided Search and 7 more 2022-08-08 5.0 MEDIUM 7.5 HIGH
XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible.
CVE-2021-4115 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2022-08-08 2.1 LOW 5.5 MEDIUM
There is a flaw in polkit which can allow an unprivileged user to cause polkit to crash, due to process file descriptor exhaustion. The highest threat from this vulnerability is to availability. NOTE: Polkit process outage duration is tied to the failing process being reaped and a new one being spawned
CVE-2020-35176 3 Awstats, Debian, Fedoraproject 3 Awstats, Debian Linux, Fedora 2022-08-05 5.0 MEDIUM 5.3 MEDIUM
In AWStats through 7.8, cgi-bin/awstats.pl?config= accepts a partial absolute pathname (omitting the initial /etc), even though it was intended to only read a file in the /etc/awstats/awstats.conf format. NOTE: this issue exists because of an incomplete fix for CVE-2017-1000501 and CVE-2020-29600.
CVE-2020-27828 2 Fedoraproject, Jasper Project 2 Fedora, Jasper 2022-08-05 6.8 MEDIUM 7.8 HIGH
There's a flaw in jasper's jpc encoder in versions prior to 2.0.23. Crafted input provided to jasper by an attacker could cause an arbitrary out-of-bounds write. This could potentially affect data confidentiality, integrity, or application availability.
CVE-2020-13584 2 Fedoraproject, Webkitgtk 2 Fedora, Webkitgtk 2022-08-05 6.8 MEDIUM 8.8 HIGH
An exploitable use-after-free vulnerability exists in WebKitGTK browser version 2.30.1 x64. A specially crafted HTML web page can cause a use-after-free condition, resulting in a remote code execution. The victim needs to visit a malicious web site to trigger this vulnerability.
CVE-2020-27783 6 Debian, Fedoraproject, Lxml and 3 more 8 Debian Linux, Fedora, Lxml and 5 more 2022-08-05 4.3 MEDIUM 6.1 MEDIUM
A XSS vulnerability was discovered in python-lxml's clean module. The module's parser didn't properly imitate browsers, which caused different behaviors between the sanitizer and the user's page. A remote attacker could exploit this flaw to run arbitrary HTML/JS code.
CVE-2022-0419 2 Fedoraproject, Radare 2 Fedora, Radare2 2022-08-05 4.3 MEDIUM 5.5 MEDIUM
NULL Pointer Dereference in GitHub repository radareorg/radare2 prior to 5.6.0.
CVE-2022-1379 2 Fedoraproject, Plantuml 2 Fedora, Plantuml 2022-08-05 6.4 MEDIUM 9.1 CRITICAL
URL Restriction Bypass in GitHub repository plantuml/plantuml prior to V1.2022.5. An attacker can abuse this to bypass URL restrictions that are imposed by the different security profiles and achieve server side request forgery (SSRF). This allows accessing restricted internal resources/servers or sending requests to third party servers.
CVE-2021-20281 2 Fedoraproject, Moodle 2 Fedora, Moodle 2022-08-05 5.0 MEDIUM 5.3 MEDIUM
It was possible for some users without permission to view other users' full names to do so via the online users block in moodle before 3.10.2, 3.9.5, 3.8.8, 3.5.17.
CVE-2021-20283 2 Fedoraproject, Moodle 2 Fedora, Moodle 2022-08-05 4.0 MEDIUM 4.3 MEDIUM
The web service responsible for fetching other users' enrolled courses did not validate that the requesting user had permission to view that information in each course in moodle before 3.10.2, 3.9.5, 3.8.8, 3.5.17.
CVE-2019-2737 5 Canonical, Fedoraproject, Mariadb and 2 more 5 Ubuntu Linux, Fedora, Mariadb and 2 more 2022-08-05 4.0 MEDIUM 4.9 MEDIUM
