CVE-2019-9514 | 13 Apache, Apple, Canonical and 10 more | 44 Traffic Server, Mac Os X, Swiftnio and 41 more | 2025-01-14 | 7.5 High |
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. | ||||
CVE-2019-9517 | 12 Apache, Apple, Canonical and 9 more | 28 Http Server, Traffic Server, Mac Os X and 25 more | 2025-01-14 | 7.5 High |
Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. | ||||
CVE-2019-9515 | 12 Apache, Apple, Canonical and 9 more | 36 Traffic Server, Mac Os X, Swiftnio and 33 more | 2025-01-14 | 7.5 High |
Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. | ||||
CVE-2019-9513 | 12 Apache, Apple, Canonical and 9 more | 25 Traffic Server, Mac Os X, Swiftnio and 22 more | 2025-01-14 | 7.5 High |
Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU. | ||||
CVE-2019-9516 | 12 Apache, Apple, Canonical and 9 more | 24 Traffic Server, Mac Os X, Swiftnio and 21 more | 2025-01-14 | 6.5 Medium |
Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory. | ||||
CVE-2019-9511 | 12 Apache, Apple, Canonical and 9 more | 29 Traffic Server, Mac Os X, Swiftnio and 26 more | 2025-01-14 | 7.5 High |
Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. | ||||
CVE-2023-2455 | 3 Fedoraproject, Postgresql, Redhat | 9 Fedora, Postgresql, Enterprise Linux and 6 more | 2025-01-06 | 5.4 Medium |
Row security policies disregard user ID changes after inlining; PostgreSQL could permit incorrect policies to be applied in certain cases where role-specific policies are used and a given query is planned under one role and then executed under other roles. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications. This affects only databases that have used CREATE POLICY to define a row security policy. | ||||
CVE-2022-4904 | 3 C-ares Project, Fedoraproject, Redhat | 6 C-ares, Fedora, Enterprise Linux and 3 more | 2024-11-21 | 8.6 High |
A flaw was found in the c-ares package. The ares_set_sortlist is missing checks about the validity of the input string, which allows a possible arbitrary length stack overflow. This issue may cause a denial of service or a limited impact on confidentiality and integrity. | ||||
CVE-2022-0711 | 3 Debian, Haproxy, Redhat | 6 Debian Linux, Haproxy, Enterprise Linux and 3 more | 2024-11-21 | 7.5 High |
A flaw was found in the way HAProxy processed HTTP responses containing the "Set-Cookie2" header. This flaw could allow an attacker to send crafted HTTP response packets which lead to an infinite loop, eventually resulting in a denial of service condition. The highest threat from this vulnerability is availability. | ||||
CVE-2021-4189 | 4 Debian, Netapp, Python and 1 more | 6 Debian Linux, Ontap Select Deploy Administration Utility, Python and 3 more | 2024-11-21 | 5.3 Medium |
A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV (passive) mode. The issue is how the FTP client trusts the host from the PASV response by default. This flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which otherwise would not have been possible. | ||||
CVE-2021-4104 | 4 Apache, Fedoraproject, Oracle and 1 more | 59 Log4j, Fedora, Advanced Supply Chain Planning and 56 more | 2024-11-21 | 7.5 High |
JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. | ||||
CVE-2021-41817 | 6 Debian, Fedoraproject, Opensuse and 3 more | 12 Debian Linux, Fedora, Factory and 9 more | 2024-11-21 | 7.5 High |
Date.parse in the date gem through 3.2.0 for Ruby allows ReDoS (regular expression Denial of Service) via a long string. The fixed versions are 3.2.1, 3.1.2, 3.0.2, and 2.0.1. | ||||
CVE-2021-3677 | 3 Fedoraproject, Postgresql, Redhat | 9 Fedora, Postgresql, Enterprise Linux and 6 more | 2024-11-21 | 6.5 Medium |
A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting. | ||||
CVE-2021-3656 | 3 Fedoraproject, Linux, Redhat | 31 Fedora, Linux Kernel, 3scale Api Management and 28 more | 2024-11-21 | 8.8 High |
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. | ||||
CVE-2021-3426 | 6 Debian, Fedoraproject, Netapp and 3 more | 11 Debian Linux, Fedora, Cloud Backup and 8 more | 2024-11-21 | 5.7 Medium |
There's a flaw in Python 3's pydoc. A local or adjacent attacker who discovers or is able to convince another local or adjacent user to start a pydoc server could access the server and use it to disclose sensitive information belonging to the other user that they would not normally be able to access. The highest risk of this flaw is to data confidentiality. This flaw affects Python versions before 3.8.9, Python versions before 3.9.3 and Python versions before 3.10.0a7. | ||||
CVE-2021-3393 | 2 Postgresql, Redhat | 5 Postgresql, Enterprise Linux, Rhel Eus and 2 more | 2024-11-21 | 4.3 Medium |
An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11. A user having UPDATE permission but not SELECT permission to a particular column could craft queries which, under some circumstances, might disclose values from that column in error messages. An attacker could use this flaw to obtain information stored in a column they are allowed to write but not read. | ||||
CVE-2021-32672 | 6 Debian, Fedoraproject, Netapp and 3 more | 9 Debian Linux, Fedora, Management Services For Element Software and 6 more | 2024-11-21 | 5.3 Medium |
Redis is an open source, in-memory database that persists on disk. When using the Redis Lua Debugger, users can send malformed requests that cause the debugger’s protocol parser to read data beyond the actual buffer. This issue affects all versions of Redis with Lua debugging support (3.2 or newer). The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14. | ||||
CVE-2021-32027 | 2 Postgresql, Redhat | 7 Postgresql, Ansible Automation Platform, Enterprise Linux and 4 more | 2024-11-21 | 8.8 High |
A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before 9.6.22. While modifying certain SQL array values, missing bounds checks let authenticated database users write arbitrary bytes to a wide area of server memory. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
CVE-2021-23214 | 3 Fedoraproject, Postgresql, Redhat | 7 Fedora, Postgresql, Enterprise Linux and 4 more | 2024-11-21 | 8.1 High |
When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption. | ||||
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. |
