CVE-2020-27825 4 Debian, Linux, Netapp and 1 more 9 Debian Linux, Linux Kernel, Cloud Backup and 6 more 2023-11-07 5.4 MEDIUM 5.7 MEDIUM
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.
CVE-2020-29486 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2023-11-07 4.9 MEDIUM 6.0 MEDIUM
An issue was discovered in Xen through 4.14.x. Nodes in xenstore have an ownership. In oxenstored, a owner could give a node away. However, node ownership has quota implications. Any guest can run another guest out of quota, or create an unbounded number of nodes owned by dom0, thus running xenstored out of memory A malicious guest administrator can cause a denial of service against a specific guest or against the whole host. All systems using oxenstored are vulnerable. Building and using oxenstored is the default in the upstream Xen distribution, if the Ocaml compiler is available. Systems using C xenstored are not vulnerable.
CVE-2020-2757 7 Canonical, Debian, Fedoraproject and 4 more 21 Ubuntu Linux, Debian Linux, Fedora and 18 more 2023-11-07 4.3 MEDIUM 3.7 LOW

CVE-2020-29130 3 Debian, Fedoraproject, Libslirp Project 3 Debian Linux, Fedora, Libslirp 2023-11-07 4.0 MEDIUM 4.3 MEDIUM
slirp.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.
CVE-2020-35480 3 Debian, Fedoraproject, Mediawiki 3 Debian Linux, Fedora, Mediawiki 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
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.
CVE-2020-28033 3 Debian, Fedoraproject, Wordpress 3 Debian Linux, Fedora, Wordpress 2023-11-07 5.0 MEDIUM 7.5 HIGH
WordPress before 5.5.2 mishandles embeds from disabled sites on a multisite network, as demonstrated by allowing a spam embed.
CVE-2020-35477 3 Debian, Fedoraproject, Mediawiki 3 Debian Linux, Fedora, Mediawiki 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
MediaWiki before 1.35.1 blocks legitimate attempts to hide log entries in some situations. If one sets MediaWiki:Mainpage to Special:MyLanguage/Main Page, visits a log entry on Special:Log, and toggles the "Change visibility of selected log entries" checkbox (or a tags checkbox) next to it, there is a redirection to the main page's action=historysubmit (instead of the desired behavior in which a revision-deletion form appears).
CVE-2020-28636 3 Cgal, Debian, Fedoraproject 3 Computational Geometry Algorithms Library, Debian Linux, Fedora 2023-11-07 7.5 HIGH 9.8 CRITICAL
A code execution vulnerability exists in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1. An oob read vulnerability exists in Nef_S2/SNC_io_parser.h SNC_io_parser::read_sloop() slh->twin() An attacker can provide malicious input to trigger this vulnerability.
CVE-2020-27844 3 Debian, Oracle, Uclouvain 3 Debian Linux, Outside In Technology, Openjpeg 2023-11-07 8.3 HIGH 7.8 HIGH
A flaw was found in openjpeg's src/lib/openjp2/t2.c in versions prior to 2.4.0. This flaw allows an attacker to provide crafted input to openjpeg during conversion and encoding, causing an out-of-bounds write. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2020-29483 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2023-11-07 4.9 MEDIUM 6.5 MEDIUM
An issue was discovered in Xen through 4.14.x. Xenstored and guests communicate via a shared memory page using a specific protocol. When a guest violates this protocol, xenstored will drop the connection to that guest. Unfortunately, this is done by just removing the guest from xenstored's internal management, resulting in the same actions as if the guest had been destroyed, including sending an @releaseDomain event. @releaseDomain events do not say that the guest has been removed. All watchers of this event must look at the states of all guests to find the guest that has been removed. When an @releaseDomain is generated due to a domain xenstored protocol violation, because the guest is still running, the watchers will not react. Later, when the guest is actually destroyed, xenstored will no longer have it stored in its internal data base, so no further @releaseDomain event will be sent. This can lead to a zombie domain; memory mappings of that guest's memory will not be removed, due to the missing event. This zombie domain will be cleaned up only after another domain is destroyed, as that will trigger another @releaseDomain event. If the device model of the guest that violated the Xenstore protocol is running in a stub-domain, a use-after-free case could happen in xenstored, after having removed the guest from its internal data base, possibly resulting in a crash of xenstored. A malicious guest can block resources of the host for a period after its own death. Guests with a stub domain device model can eventually crash xenstored, resulting in a more serious denial of service (the prevention of any further domain management operations). Only the C variant of Xenstore is affected; the Ocaml variant is not affected. Only HVM guests with a stubdom device model can cause a serious DoS.
CVE-2020-28601 3 Cgal, Debian, Fedoraproject 3 Computational Geometry Algorithms Library, Debian Linux, Fedora 2023-11-07 7.5 HIGH 9.8 CRITICAL
A code execution vulnerability exists in the Nef polygon-parsing functionality of CGAL libcgal CGAL-5.1.1. An oob read vulnerability exists in Nef_2/PM_io_parser.h PM_io_parser::read_vertex() Face_of[] OOB read. An attacker can provide malicious input to trigger this vulnerability.
CVE-2020-28035 3 Debian, Fedoraproject, Wordpress 3 Debian Linux, Fedora, Wordpress 2023-11-07 7.5 HIGH 9.8 CRITICAL
WordPress before 5.5.2 allows attackers to gain privileges via XML-RPC.
CVE-2020-27813 2 Debian, Gorillatoolkit 2 Debian Linux, Websocket 2023-11-07 5.0 MEDIUM 7.5 HIGH
An integer overflow vulnerability exists with the length of websocket frames received via a websocket connection. An attacker would use this flaw to cause a denial of service attack on an HTTP Server allowing websocket connections.
CVE-2020-35523 4 Debian, Libtiff, Netapp and 1 more 4 Debian Linux, Libtiff, Ontap Select Deploy Administration Utility and 1 more 2023-11-07 6.8 MEDIUM 7.8 HIGH
An integer overflow flaw was found in libtiff that exists in the tif_getimage.c file. This flaw allows an attacker to inject and execute arbitrary code when a user opens a crafted TIFF file. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2020-27773 3 Debian, Imagemagick, Redhat 3 Debian Linux, Imagemagick, Enterprise Linux 2023-11-07 4.3 MEDIUM 3.3 LOW
A flaw was found in ImageMagick in MagickCore/gem-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type `unsigned char` or division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.
