A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.
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-2021-37137 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-2021-32838 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-2021-32640 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-2021-32740 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-2021-32918 4 Debian, Fedoraproject, Lua and 1 more 4 Debian Linux, Fedora, Lua and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH

CVE-2021-21419 2 Eventlet, Fedoraproject 2 Eventlet, Fedora 2023-11-07 5.0 MEDIUM 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-2021-22880 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.
