CVE-2020-8664 2 Cncf, Redhat 2 Envoy, Service Mesh 2024-11-21 5.3 Medium
CNCF Envoy through 1.13.0 has incorrect Access Control when using SDS with Combined Validation Context. Using the same secret (e.g. trusted CA) across many resources together with the combined validation context could lead to the “static” part of the validation context to be not applied, even though it was visible in the active config dump.
CVE-2020-8663 2 Envoyproxy, Redhat 2 Envoy, Service Mesh 2024-11-21 7.5 High
Envoy version 1.14.2, 1.13.2, 1.12.4 or earlier may exhaust file descriptors and/or memory when accepting too many connections.
CVE-2020-8661 2 Cncf, Redhat 3 Envoy, Openshift Service Mesh, Service Mesh 2024-11-21 7.5 High
CNCF Envoy through 1.13.0 may consume excessive amounts of memory when responding internally to pipelined requests.
CVE-2020-8660 2 Envoyproxy, Redhat 2 Envoy, Service Mesh 2024-11-21 5.3 Medium
CNCF Envoy through 1.13.0 TLS inspector bypass. TLS inspector could have been bypassed (not recognized as a TLS client) by a client using only TLS 1.3. Because TLS extensions (SNI, ALPN) were not inspected, those connections might have been matched to a wrong filter chain, possibly bypassing some security restrictions in the process.
CVE-2020-8659 3 Cncf, Debian, Redhat 4 Envoy, Debian Linux, Openshift Service Mesh and 1 more 2024-11-21 7.5 High
CNCF Envoy through 1.13.0 may consume excessive amounts of memory when proxying HTTP/1.1 requests or responses with many small (i.e. 1 byte) chunks.
CVE-2020-8649 4 Debian, Linux, Opensuse and 1 more 6 Debian Linux, Linux Kernel, Leap and 3 more 2024-11-21 5.9 Medium
There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c.
CVE-2020-8648 7 Broadcom, Canonical, Debian and 4 more 14 Brocade Fabric Operating System Firmware, Ubuntu Linux, Debian Linux and 11 more 2024-11-21 7.1 High

CVE-2020-8647 4 Debian, Linux, Opensuse and 1 more 6 Debian Linux, Linux Kernel, Leap and 3 more 2024-11-21 6.1 Medium
There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c.
CVE-2020-8632 4 Canonical, Debian, Opensuse and 1 more 4 Cloud-init, Debian Linux, Leap and 1 more 2024-11-21 5.5 Medium
In cloud-init through 19.4, rand_user_password in cloudinit/config/cc_set_passwords.py has a small default pwlen value, which makes it easier for attackers to guess passwords.
CVE-2020-8631 4 Canonical, Debian, Opensuse and 1 more 4 Cloud-init, Debian Linux, Leap and 1 more 2024-11-21 5.5 Medium
cloud-init through 19.4 relies on Mersenne Twister for a random password, which makes it easier for attackers to predict passwords, because rand_str in cloudinit/util.py calls the random.choice function.
CVE-2020-8625 6 Debian, Fedoraproject, Isc and 3 more 15 Debian Linux, Fedora, Bind and 12 more 2024-11-21 8.1 High
BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers. The most likely outcome of a successful exploitation of the vulnerability is a crash of the named process. However, remote code execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -> 9.11.27, 9.12.0 -> 9.16.11, and versions BIND 9.11.3-S1 -> 9.11.27-S1 and 9.16.8-S1 -> 9.16.11-S1 of BIND Supported Preview Edition. Also release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch
CVE-2020-8624 7 Canonical, Debian, Fedoraproject and 4 more 8 Ubuntu Linux, Debian Linux, Fedora and 5 more 2024-11-21 4.3 Medium
In BIND 9.9.12 -> 9.9.13, 9.10.7 -> 9.10.8, 9.11.3 -> 9.11.21, 9.12.1 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.12-S1 -> 9.9.13-S1, 9.11.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker who has been granted privileges to change a specific subset of the zone's content could abuse these unintended additional privileges to update other contents of the zone.
CVE-2020-8623 8 Canonical, Debian, Fedoraproject and 5 more 9 Ubuntu Linux, Debian Linux, Fedora and 6 more 2024-11-21 7.5 High
In BIND 9.10.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.10.5-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker that can reach a vulnerable system with a specially crafted query packet can trigger a crash. To be vulnerable, the system must: * be running BIND that was built with "--enable-native-pkcs11" * be signing one or more zones with an RSA key * be able to receive queries from a possible attacker
CVE-2020-8622 9 Canonical, Debian, Fedoraproject and 6 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2024-11-21 6.5 Medium
In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker on the network path for a TSIG-signed request, or operating the server receiving the TSIG-signed request, could send a truncated response to that request, triggering an assertion failure, causing the server to exit. Alternately, an off-path attacker would have to correctly guess when a TSIG-signed request was sent, along with other characteristics of the packet and message, and spoof a truncated response to trigger an assertion failure, causing the server to exit.
CVE-2020-8619 7 Canonical, Debian, Fedoraproject and 4 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2024-11-21 4.9 Medium
In ISC BIND9 versions BIND 9.11.14 -> 9.11.19, BIND 9.14.9 -> 9.14.12, BIND 9.16.0 -> 9.16.3, BIND Supported Preview Edition 9.11.14-S1 -> 9.11.19-S1: Unless a nameserver is providing authoritative service for one or more zones and at least one zone contains an empty non-terminal entry containing an asterisk ("*") character, this defect cannot be encountered. A would-be attacker who is allowed to change zone content could theoretically introduce such a record in order to exploit this condition to cause denial of service, though we consider the use of this vector unlikely because any such attack would require a significant privilege level and be easily traceable.
CVE-2020-8617 6 Canonical, Debian, Fedoraproject and 3 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2024-11-21 7.5 High
Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an inconsistent state if the attacker knows (or successfully guesses) the name of a TSIG key used by the server. Since BIND, by default, configures a local session key even on servers whose configuration does not otherwise make use of it, almost all current BIND servers are vulnerable. In releases of BIND dating from March 2018 and after, an assertion check in tsig.c detects this inconsistent state and deliberately exits. Prior to the introduction of the check the server would continue operating in an inconsistent state, with potentially harmful results.
CVE-2020-8616 3 Debian, Isc, Redhat 7 Debian Linux, Bind, Enterprise Linux and 4 more 2024-11-21 8.6 High
A malicious actor who intentionally exploits this lack of effective limitation on the number of fetches performed when processing referrals can, through the use of specially crafted referrals, cause a recursing server to issue a very large number of fetches in an attempt to process the referral. This has at least two potential effects: The performance of the recursing server can potentially be degraded by the additional work required to perform these fetches, and The attacker can exploit this behavior to use the recursing server as a reflector in a reflection attack with a high amplification factor.
CVE-2020-8608 4 Debian, Libslirp Project, Opensuse and 1 more 11 Debian Linux, Libslirp, Leap and 8 more 2024-11-21 5.6 Medium
In libslirp 4.1.0, as used in QEMU 4.2.0, tcp_subr.c misuses snprintf return values, leading to a buffer overflow in later code.
CVE-2020-8597 5 Canonical, Debian, Point-to-point Protocol Project and 2 more 8 Ubuntu Linux, Debian Linux, Point-to-point Protocol and 5 more 2024-11-21 9.8 Critical
eap.c in pppd in ppp 2.4.2 through 2.4.8 has an rhostname buffer overflow in the eap_request and eap_response functions.
CVE-2020-8595 2 Istio, Redhat 4 Istio, Enterprise Linux, Openshift Service Mesh and 1 more 2024-11-21 7.3 High
Istio versions 1.2.10 (End of Life) and prior, 1.3 through 1.3.7, and 1.4 through 1.4.3 allows authentication bypass. The Authentication Policy exact-path matching logic can allow unauthorized access to HTTP paths even if they are configured to be only accessed after presenting a valid JWT token. For example, an attacker can add a ? or # character to a URI that would otherwise satisfy an exact-path match.
