CVE-2021-3735 2 Debian, Qemu 2 Debian Linux, Qemu 2023-11-07 N/A 4.4 MEDIUM
A deadlock issue was found in the AHCI controller device of QEMU. It occurs on a software reset (ahci_reset_port) while handling a host-to-device Register FIS (Frame Information Structure) packet from the guest. A privileged user inside the guest could use this flaw to hang the QEMU process on the host, resulting in a denial of service condition. The highest threat from this vulnerability is to system availability.
CVE-2021-3622 2 Fedoraproject, Redhat 4 Fedora, Enterprise Linux, Enterprise Linux Workstation and 1 more 2023-11-07 4.3 MEDIUM 4.3 MEDIUM
A flaw was found in the hivex library. This flaw allows an attacker to input a specially crafted Windows Registry (hive) file, which would cause hivex to recursively call the _get_children() function, leading to a stack overflow. The highest threat from this vulnerability is to system availability.
CVE-2021-37137 5 Debian, Netapp, Netty and 2 more 12 Debian Linux, Oncommand Insight, Netty and 9 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which may lead to excessive memory usage as well. This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable chunk.
CVE-2021-37136 5 Debian, Netapp, Netty and 2 more 19 Debian Linux, Oncommand Insight, Netty and 16 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
The Bzip2 decompression decoder function doesn't allow setting size restrictions on the decompressed output data (which affects the allocation size used during decompression). All users of Bzip2Decoder are affected. The malicious input can trigger an OOME and so a DoS attack
CVE-2021-34792 1 Cisco 18 Adaptive Security Appliance Software, Asa 5505, Asa 5505 Firmware and 15 more 2023-11-07 7.8 HIGH 7.5 HIGH
A vulnerability in the memory management of Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper resource management when connection rates are high. An attacker could exploit this vulnerability by opening a significant number of connections on an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.
CVE-2021-33503 3 Fedoraproject, Oracle, Python 5 Fedora, Enterprise Manager Ops Center, Instantis Enterprisetrack and 2 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
An issue was discovered in urllib3 before 1.26.5. When provided with a URL containing many @ characters in the authority component, the authority regular expression exhibits catastrophic backtracking, causing a denial of service if a URL were passed as a parameter or redirected to via an HTTP redirect.
CVE-2021-32918 4 Debian, Fedoraproject, Lua and 1 more 4 Debian Linux, Fedora, Lua and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Prosody before 0.11.9. Default settings are susceptible to remote unauthenticated denial-of-service (DoS) attacks via memory exhaustion when running under Lua 5.2 or Lua 5.3.
CVE-2021-32838 2 Fedoraproject, Flask-restx Project 2 Fedora, Flask-restx 2023-11-07 5.0 MEDIUM 7.5 HIGH
Flask-RESTX (pypi package flask-restx) is a community driven fork of Flask-RESTPlus. Flask-RESTX before version 0.5.1 is vulnerable to ReDoS (Regular Expression Denial of Service) in email_regex. This is fixed in version 0.5.1.
CVE-2021-32740 2 Addressable Project, Fedoraproject 2 Addressable, Fedora 2023-11-07 5.0 MEDIUM 7.5 HIGH
Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard library. An uncontrolled resource consumption vulnerability exists after version 2.3.0 through version 2.7.0. Within the URI template implementation in Addressable, a maliciously crafted template may result in uncontrolled resource consumption, leading to denial of service when matched against a URI. In typical usage, templates would not normally be read from untrusted user input, but nonetheless, no previous security advisory for Addressable has cautioned against doing this. Users of the parsing capabilities in Addressable but not the URI template capabilities are unaffected. The vulnerability is patched in version 2.8.0. As a workaround, only create Template objects from trusted sources that have been validated not to produce catastrophic backtracking.
CVE-2021-32640 2 Netapp, Ws Project 2 E-series Performance Analyzer, Ws 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
ws is an open source WebSocket client and server library for Node.js. A specially crafted value of the `Sec-Websocket-Protocol` header can be used to significantly slow down a ws server. The vulnerability has been fixed in ws@7.4.6 (https://github.com/websockets/ws/commit/00c425ec77993773d823f018f64a5c44e17023ff). In vulnerable versions of ws, the issue can be mitigated by reducing the maximum allowed length of the request headers using the [`--max-http-header-size=size`](https://nodejs.org/api/cli.html#cli_max_http_header_size_size) and/or the [`maxHeaderSize`](https://nodejs.org/api/http.html#http_http_createserver_options_requestlistener) options.
CVE-2021-30468 2 Apache, Oracle 5 Cxf, Tomee, Business Intelligence and 2 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
A vulnerability in the JsonMapObjectReaderWriter of Apache CXF allows an attacker to submit malformed JSON to a web service, which results in the thread getting stuck in an infinite loop, consuming CPU indefinitely. This issue affects Apache CXF versions prior to 3.4.4; Apache CXF versions prior to 3.3.11.
CVE-2021-29471 2 Fedoraproject, Matrix 2 Fedora, Synapse 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
Synapse is a Matrix reference homeserver written in python (pypi package matrix-synapse). Matrix is an ecosystem for open federated Instant Messaging and VoIP. In Synapse before version 1.33.2 "Push rules" can specify conditions under which they will match, including `event_match`, which matches event content against a pattern including wildcards. Certain patterns can cause very poor performance in the matching engine, leading to a denial-of-service when processing moderate length events. The issue is patched in version 1.33.2. A potential workaround might be to prevent users from making custom push rules, by blocking such requests at a reverse-proxy.
CVE-2021-28165 4 Eclipse, Jenkins, Netapp and 1 more 21 Jetty, Jenkins, Cloud Manager and 18 more 2023-11-07 7.8 HIGH 7.5 HIGH
In Eclipse Jetty 7.2.2 to 9.4.38, 10.0.0.alpha0 to 10.0.1, and 11.0.0.alpha0 to 11.0.1, CPU usage can reach 100% upon receiving a large invalid TLS frame.
CVE-2021-28089 2 Fedoraproject, Torproject 2 Fedora, Tor 2023-11-07 5.0 MEDIUM 7.5 HIGH
Tor before 0.4.5.7 allows a remote participant in the Tor directory protocol to exhaust CPU resources on a target, aka TROVE-2021-001.
CVE-2021-26260 3 Debian, Fedoraproject, Openexr 3 Debian Linux, Fedora, Openexr 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
An integer overflow leading to a heap-buffer overflow was found in the DwaCompressor of OpenEXR in versions before 3.0.1. An attacker could use this flaw to crash an application compiled with OpenEXR. This is a different flaw from CVE-2021-23215.
CVE-2021-23215 3 Debian, Fedoraproject, Openexr 3 Debian Linux, Fedora, Openexr 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
An integer overflow leading to a heap-buffer overflow was found in the DwaCompressor of OpenEXR in versions before 3.0.1. An attacker could use this flaw to crash an application compiled with OpenEXR.
CVE-2021-22883 5 Fedoraproject, Netapp, Nodejs and 2 more 9 Fedora, E-series Performance Analyzer, Node.js and 6 more 2023-11-07 7.8 HIGH 7.5 HIGH
Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to a denial of service attack when too many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory.
CVE-2021-22880 2 Fedoraproject, Rubyonrails 2 Fedora, Rails 2023-11-07 5.0 MEDIUM 7.5 HIGH
The PostgreSQL adapter in Active Record before 6.1.2.1, 6.0.3.5, 5.2.4.5 suffers from a regular expression denial of service (REDoS) vulnerability. Carefully crafted input can cause the input validation in the `money` type of the PostgreSQL adapter in Active Record to spend too much time in a regular expression, resulting in the potential for a DoS attack. This only impacts Rails applications that are using PostgreSQL along with money type columns that take user input.
CVE-2021-22696 2 Apache, Oracle 6 Cxf, Business Intelligence, Communications Diameter Intelligence Hub and 3 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
CXF supports (via JwtRequestCodeFilter) passing OAuth 2 parameters via a JWT token as opposed to query parameters (see: The OAuth 2.0 Authorization Framework: JWT Secured Authorization Request (JAR)). Instead of sending a JWT token as a "request" parameter, the spec also supports specifying a URI from which to retrieve a JWT token from via the "request_uri" parameter. CXF was not validating the "request_uri" parameter (apart from ensuring it uses "https) and was making a REST request to the parameter in the request to retrieve a token. This means that CXF was vulnerable to DDos attacks on the authorization server, as specified in section 10.4.1 of the spec. This issue affects Apache CXF versions prior to 3.4.3; Apache CXF versions prior to 3.3.10.
CVE-2021-22119 2 Oracle, Vmware 2 Communications Cloud Native Core Policy, Spring Security 2023-11-07 5.0 MEDIUM 7.5 HIGH
Spring Security versions 5.5.x prior to 5.5.1, 5.4.x prior to 5.4.7, 5.3.x prior to 5.3.10 and 5.2.x prior to 5.2.11 are susceptible to a Denial-of-Service (DoS) attack via the initiation of the Authorization Request in an OAuth 2.0 Client Web and WebFlux application. A malicious user or attacker can send multiple requests initiating the Authorization Request for the Authorization Code Grant, which has the potential of exhausting system resources using a single session or multiple sessions.
