CVE-2021-21419 3 Eventlet, Fedoraproject, Redhat 4 Eventlet, Fedora, Openshift and 1 more 2024-11-21 5.3 Medium
Eventlet is a concurrent networking library for Python. A websocket peer may exhaust memory on Eventlet side by sending very large websocket frames. Malicious peer may exhaust memory on Eventlet side by sending highly compressed data frame. A patch in version 0.31.0 restricts websocket frame to reasonable limits. As a workaround, restricting memory usage via OS limits would help against overall machine exhaustion, but there is no workaround to protect Eventlet process.
CVE-2021-21240 2 Httplib2 Project, Redhat 2 Httplib2, Openstack 2024-11-21 7.5 High
httplib2 is a comprehensive HTTP client library for Python. In httplib2 before version 0.19.0, a malicious server which responds with long series of "\xa0" characters in the "www-authenticate" header may cause Denial of Service (CPU burn while parsing header) of the httplib2 client accessing said server. This is fixed in version 0.19.0 which contains a new implementation of auth headers parsing using the pyparsing library.
CVE-2021-20270 4 Debian, Fedoraproject, Pygments and 1 more 9 Debian Linux, Fedora, Pygments and 6 more 2024-11-21 7.5 High
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-2021-20267 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-2021-20257 4 Debian, Fedoraproject, Qemu and 1 more 9 Debian Linux, Fedora, Qemu and 6 more 2024-11-21 6.5 Medium
An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits (tx) descriptors in process_tx_desc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-9543 2 Openstack, Redhat 2 Manila, Openstack 2024-11-21 8.3 High
OpenStack Manila <7.4.1, >=8.0.0 <8.1.1, and >=9.0.0 <9.1.1 allows attackers to view, update, delete, or share resources that do not belong to them, because of a context-free lookup of a UUID. Attackers may also create resources, such as shared file systems and groups of shares on such share networks.
CVE-2020-9490 7 Apache, Canonical, Debian and 4 more 28 Http Server, Ubuntu Linux, Debian Linux and 25 more 2024-11-21 7.5 High
Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers.
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-2020-7039 5 Debian, Libslirp Project, Opensuse and 2 more 12 Debian Linux, Libslirp, Leap and 9 more 2024-11-21 5.6 Medium
tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in QEMU 4.2.0, mismanages memory, as demonstrated by IRC DCC commands in EMU_IRC. This can cause a heap-based buffer overflow or other out-of-bounds access which can lead to a DoS or potential execute arbitrary code.
CVE-2020-29565 3 Debian, Openstack, Redhat 3 Debian Linux, Horizon, Openstack 2024-11-21 6.1 Medium
An issue was discovered in OpenStack Horizon before 15.3.2, 16.x before 16.2.1, 17.x and 18.x before 18.3.3, 18.4.x, and 18.5.x. There is a lack of validation of the "next" parameter, which would allow someone to supply a malicious URL in Horizon that can cause an automatic redirect to the provided malicious URL.
CVE-2020-27781 2 Fedoraproject, Redhat 6 Fedora, Ceph, Ceph Storage and 3 more 2024-11-21 7.1 High
User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila, resulting in potential privilege escalation. An Open Stack Manila user can request access to a share to an arbitrary cephx user, including existing users. The access key is retrieved via the interface drivers. Then, all users of the requesting OpenStack project can view the access key. This enables the attacker to target any resource that the user has access to. This can be done to even "admin" users, compromising the ceph administrator. This flaw affects Ceph versions prior to 14.2.16, 15.x prior to 15.2.8, and 16.x prior to 16.2.0.
CVE-2020-25743 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack Platform 2024-11-21 3.2 Low
hw/ide/pci.c in QEMU before 5.1.1 can trigger a NULL pointer dereference because it lacks a pointer check before an ide_cancel_dma_sync call.
CVE-2020-25717 5 Canonical, Debian, Fedoraproject and 2 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2024-11-21 8.1 High
A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.
CVE-2020-25658 3 Fedoraproject, Python-rsa Project, Redhat 5 Fedora, Python-rsa, Ceph Storage and 2 more 2024-11-21 7.5 High
It was found that python-rsa is vulnerable to Bleichenbacher timing attacks. An attacker can use this flaw via the RSA decryption API to decrypt parts of the cipher text encrypted with RSA.
CVE-2020-1983 6 Canonical, Debian, Fedoraproject and 3 more 9 Ubuntu Linux, Debian Linux, Fedora and 6 more 2024-11-21 7.5 High
A use after free vulnerability in ip_reass() in ip_input.c of libslirp 4.2.0 and prior releases allows crafted packets to cause a denial of service.
CVE-2020-1759 3 Fedoraproject, Linuxfoundation, Redhat 5 Fedora, Ceph, Ceph Storage and 2 more 2024-11-21 6.4 Medium
A vulnerability was found in Red Hat Ceph Storage 4 and Red Hat Openshift Container Storage 4.2 where, A nonce reuse vulnerability was discovered in the secure mode of the messenger v2 protocol, which can allow an attacker to forge auth tags and potentially manipulate the data by leveraging the reuse of a nonce in a session. Messages encrypted using a reused nonce value are susceptible to serious confidentiality and integrity attacks.
CVE-2020-1758 1 Redhat 4 Jboss Single Sign On, Keycloak, Openstack and 1 more 2024-11-21 5.3 Medium
A flaw was found in Keycloak in versions before 10.0.0, where it does not perform the TLS hostname verification while sending emails using the SMTP server. This flaw allows an attacker to perform a man-in-the-middle (MITM) attack.
CVE-2020-1740 3 Debian, Fedoraproject, Redhat 7 Debian Linux, Fedora, Ansible and 4 more 2024-11-21 3.9 Low
A flaw was found in Ansible Engine when using Ansible Vault for editing encrypted files. When a user executes "ansible-vault edit", another user on the same computer can read the old and new secret, as it is created in a temporary file with mkstemp and the returned file descriptor is closed and the method write_data is called to write the existing secret in the file. This method will delete the file before recreating it insecurely. All versions in 2.7.x, 2.8.x and 2.9.x branches are believed to be vulnerable.
CVE-2020-1739 3 Debian, Fedoraproject, Redhat 7 Debian Linux, Fedora, Ansible and 4 more 2024-11-21 3.9 Low
A flaw was found in Ansible 2.7.16 and prior, 2.8.8 and prior, and 2.9.5 and prior when a password is set with the argument "password" of svn module, it is used on svn command line, disclosing to other users within the same node. An attacker could take advantage by reading the cmdline file from that particular PID on the procfs.
CVE-2020-1738 1 Redhat 4 Ansible, Ansible Tower, Cloudforms Management Engine and 1 more 2024-11-21 3.9 Low
A flaw was found in Ansible Engine when the module package or service is used and the parameter 'use' is not specified. If a previous task is executed with a malicious user, the module sent can be selected by the attacker using the ansible facts file. All versions in 2.7.x, 2.8.x and 2.9.x branches are believed to be vulnerable.
