| CVE-2020-27170 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2023-11-07 | 1.9 LOW | 4.7 MEDIUM |
| An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This affects pointer types that do not define a ptr_limit. | |||||
| CVE-2020-26262 | 2 Coturn Project, Fedoraproject | 2 Coturn, Fedora | 2023-11-07 | 6.4 MEDIUM | 7.2 HIGH |
| Coturn is free open source implementation of TURN and STUN Server. Coturn before version 4.5.2 by default does not allow peers to connect and relay packets to loopback addresses in the range of `127.x.x.x`. However, it was observed that when sending a `CONNECT` request with the `XOR-PEER-ADDRESS` value of `0.0.0.0`, a successful response was received and subsequently, `CONNECTIONBIND` also received a successful response. Coturn then is able to relay packets to the loopback interface. Additionally, when coturn is listening on IPv6, which is default, the loopback interface can also be reached by making use of either `[::1]` or `[::]` as the peer address. By using the address `0.0.0.0` as the peer address, a malicious user will be able to relay packets to the loopback interface, unless `--denied-peer-ip=0.0.0.0` (or similar) has been specified. Since the default configuration implies that loopback peers are not allowed, coturn administrators may choose to not set the `denied-peer-ip` setting. The issue patched in version 4.5.2. As a workaround the addresses in the address block `0.0.0.0/8`, `[::1]` and `[::]` should be denied by default unless `--allow-loopback-peers` has been specified. | |||||

| Crash in USB HID protocol dissector and possibly other dissectors in Wireshark 3.4.0 and 3.2.0 to 3.2.8 allows denial of service via packet injection or crafted capture file. | |||||
| CVE-2020-26519 | 3 Artifex, Debian, Fedoraproject | 3 Mupdf, Debian Linux, Fedora | 2023-11-07 | 4.3 MEDIUM | 5.5 MEDIUM |
| Artifex MuPDF before 1.18.0 has a heap based buffer over-write when parsing JBIG2 files allowing attackers to cause a denial of service. | |||||
| CVE-2020-27749 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2023-11-07 | 7.2 HIGH | 6.7 MEDIUM |
| A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supplied command line into their corresponding variable contents, using a 1kB stack buffer for temporary storage, without sufficient bounds checking. If the function is called with a command line that references a variable with a sufficiently large payload, it is possible to overflow the stack buffer, corrupt the stack frame and control execution which could also circumvent Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-27675 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2023-11-07 | 4.7 MEDIUM | 4.7 MEDIUM |
| An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/events_base.c allows event-channel removal during the event-handling loop (a race condition). This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash via events for an in-reconfiguration paravirtualized device, aka CID-073d0552ead5. | |||||
| CVE-2020-24659 | 4 Canonical, Fedoraproject, Gnu and 1 more | 4 Ubuntu Linux, Fedora, Gnutls and 1 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure. | |||||
| CVE-2020-25647 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2023-11-07 | 7.2 HIGH | 7.6 HIGH |
| A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-26121 | 2 Fedoraproject, Mediawiki | 2 Fedora, Mediawiki | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in the FileImporter extension for MediaWiki before 1.34.4. An attacker can import a file even when the target page is protected against "page creation" and the attacker should not be able to create it. This occurs because of a mishandled distinction between an upload restriction and a create restriction. An attacker cannot leverage this to overwrite anything, but can leverage this to force a wiki to have a page with a disallowed title. | |||||
| CVE-2020-25828 | 2 Fedoraproject, Mediawiki | 2 Fedora, Mediawiki | 2023-11-07 | 4.3 MEDIUM | 6.1 MEDIUM |
| An issue was discovered in MediaWiki before 1.31.10 and 1.32.x through 1.34.x before 1.34.4. The non-jqueryMsg version of mw.message().parse() doesn't escape HTML. This affects both message contents (which are generally safe) and the parameters (which can be based on user input). (When jqueryMsg is loaded, it correctly accepts only whitelisted tags in message contents, and escapes all parameters. Situations with an unloaded jqueryMsg are rare in practice, but can for example occur for Special:SpecialPages on a wiki with no extensions installed.) | |||||
| CVE-2020-25648 | 4 Fedoraproject, Mozilla, Oracle and 1 more | 6 Fedora, Network Security Services, Communications Offline Mediation Controller and 3 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| A flaw was found in the way NSS handled CCS (ChangeCipherSpec) messages in TLS 1.3. This flaw allows a remote attacker to send multiple CCS messages, causing a denial of service for servers compiled with the NSS library. The highest threat from this vulnerability is to system availability. This flaw affects NSS versions before 3.58. | |||||
| CVE-2020-26120 | 2 Fedoraproject, Mediawiki | 2 Fedora, Mediawiki | 2023-11-07 | 4.3 MEDIUM | 6.1 MEDIUM |
| XSS exists in the MobileFrontend extension for MediaWiki before 1.34.4 because section.line is mishandled during regex section line replacement from PageGateway. Using crafted HTML, an attacker can elicit an XSS attack via jQuery's parseHTML method, which can cause image callbacks to fire even without the element being appended to the DOM. | |||||
| CVE-2020-26521 | 2 Fedoraproject, Linuxfoundation | 2 Fedora, Nats-server | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| The JWT library in NATS nats-server before 2.1.9 allows a denial of service (a nil dereference in Go code). | |||||
| CVE-2020-25863 | 5 Debian, Fedoraproject, Opensuse and 2 more | 6 Debian Linux, Fedora, Leap and 3 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| In Wireshark 3.2.0 to 3.2.6, 3.0.0 to 3.0.13, and 2.6.0 to 2.6.20, the MIME Multipart dissector could crash. This was addressed in epan/dissectors/packet-multipart.c by correcting the deallocation of invalid MIME parts. | |||||
| CVE-2020-25597 | 2 Fedoraproject, Xen | 2 Fedora, Xen | 2023-11-07 | 6.1 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Xen through 4.14.x. There is mishandling of the constraint that once-valid event channels may not turn invalid. Logic in the handling of event channel operations in Xen assumes that an event channel, once valid, will not become invalid over the life time of a guest. However, operations like the resetting of all event channels may involve decreasing one of the bounds checked when determining validity. This may lead to bug checks triggering, crashing the host. An unprivileged guest may be able to crash Xen, leading to a Denial of Service (DoS) for the entire system. All Xen versions from 4.4 onwards are vulnerable. Xen versions 4.3 and earlier are not vulnerable. Only systems with untrusted guests permitted to create more than the default number of event channels are vulnerable. This number depends on the architecture and type of guest. For 32-bit x86 PV guests, this is 1023; for 64-bit x86 PV guests, and for all ARM guests, this number is 4095. Systems where untrusted guests are limited to fewer than this number are not vulnerable. Note that xl and libxl limit max_event_channels to 1023 by default, so systems using exclusively xl, libvirt+libxl, or their own toolstack based on libxl, and not explicitly setting max_event_channels, are not vulnerable. | |||||
| CVE-2020-24606 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2023-11-07 | 7.1 HIGH | 7.5 HIGH |
| Squid before 4.13 and 5.x before 5.0.4 allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peer_digest.cc mishandles EOF. | |||||
