An infinite loop in SMLLexer in Pygments versions 1.5 to 2.7.3 may lead to denial of service when performing syntax highlighting of a Standard ML (SML) source file, as demonstrated by input that only contains the "exception" keyword.
CVE-2021-20268 1 Linux 1 Linux Kernel 2024-11-21 7.8 High
An out-of-bounds access flaw was found in the Linux kernel's implementation of the eBPF code verifier in the way a user running the eBPF script calls dev_map_init_map or sock_map_alloc. This flaw allows a local user to crash the system or possibly escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-20267 2 Openstack, Redhat 2 Neutron, Openstack Platform 2024-11-21 7.1 High
A flaw was found in openstack-neutron's default Open vSwitch firewall rules. By sending carefully crafted packets, anyone in control of a server instance connected to the virtual switch can impersonate the IPv6 addresses of other systems on the network, resulting in denial of service or in some cases possibly interception of traffic intended for other destinations. Only deployments using the Open vSwitch driver are affected. Source: OpenStack project. Versions before openstack-neutron 15.3.3, openstack-neutron 16.3.1 and openstack-neutron 17.1.1 are affected.
CVE-2021-20264 2 Oracle, Redhat 2 Openjdk, Openjdk 2024-11-21 7.8 High
An insecure modification flaw in the /etc/passwd file was found in the openjdk-1.8 and openjdk-11 containers. This flaw allows an attacker with access to the container to modify the /etc/passwd and escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-20260 1 Theforeman 1 Foreman 2024-11-21 7.8 High
A flaw was found in the Foreman project. The Datacenter plugin exposes the password through the API to an authenticated local attacker with view_hosts permission. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-20259 1 Theforeman 1 Foremanfogproxmox 2024-11-21 7.8 High
A flaw was found in the Foreman project. The Proxmox compute resource exposes the password through the API to an authenticated local attacker with view_hosts permission. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Versions before foreman_fog_proxmox 0.13.1 are affected
CVE-2021-20247 3 Debian, Fedoraproject, Mbsync Project 4 Debian Linux, Extra Packages For Enterprise Linux, Fedora and 1 more 2024-11-21 7.4 High
A flaw was found in mbsync before v1.3.5 and v1.4.1. Validations of the mailbox names returned by IMAP LIST/LSUB do not occur allowing a malicious or compromised server to use specially crafted mailbox names containing '..' path components to access data outside the designated mailbox on the opposite end of the synchronization channel. The highest threat from this vulnerability is to data confidentiality and integrity.
CVE-2021-20237 1 Zeromq 1 Libzmq 2024-11-21 7.5 High
An uncontrolled resource consumption (memory leak) flaw was found in ZeroMQ's src/xpub.cpp in versions before 4.3.3. This flaw allows a remote unauthenticated attacker to send crafted PUB messages that consume excessive memory if the CURVE/ZAP authentication is disabled on the server, causing a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2021-20235 1 Zeromq 1 Libzmq 2024-11-21 8.1 High
There's a flaw in the zeromq server in versions before 4.3.3 in src/decoder_allocators.hpp. The decoder static allocator could have its sized changed, but the buffer would remain the same as it is a static buffer. A remote, unauthenticated attacker who sends a crafted request to the zeromq server could trigger a buffer overflow WRITE of arbitrary data if CURVE/ZAP authentication is not enabled. The greatest impact of this flaw is to application availability, data integrity, and confidentiality.
CVE-2021-20233 4 Fedoraproject, Gnu, Netapp and 1 more 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more 2024-11-21 8.2 High
A flaw was found in grub2 in versions prior to 2.06. Setparam_prefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters, while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-20230 2 Redhat, Stunnel 3 Enterprise Linux, Rhel Eus, Stunnel 2024-11-21 7.5 High
A flaw was found in stunnel before 5.57, where it improperly validates client certificates when it is configured to use both redirect and verifyChain options. This flaw allows an attacker with a certificate signed by a Certificate Authority, which is not the one accepted by the stunnel server, to access the tunneled service instead of being redirected to the address specified in the redirect option. The highest threat from this vulnerability is to confidentiality.
CVE-2021-20228 2 Debian, Redhat 6 Debian Linux, Ansible Automation Platform, Ansible Engine and 3 more 2024-11-21 7.5 High
A flaw was found in the Ansible Engine 2.9.18, where sensitive info is not masked by default and is not protected by the no_log feature when using the sub-option feature of the basic.py module. This flaw allows an attacker to obtain sensitive information. The highest threat from this vulnerability is to confidentiality.
