An issue was discovered on MOXA Mgate MB3180 Version 2.1 Build 18113012. Attackers can use slowhttptest tool to send incomplete HTTP request, which could make server keep waiting for the packet to finish the connection, until its resource exhausted. Then the web server is denial-of-service.

An issue was discovered on 4GEE ROUTER HH70VB Version HH70_E1_02.00_22. Attackers can use slowhttptest tool to send incomplete HTTP request, which could make server keep waiting for the packet to finish the connection, until its resource exhausted. Then the web server is denial-of-service.

An issue was discovered in UniFi Protect G3 FLEX Camera Version UVC.v4.30.0.67. Attackers can use slowhttptest tool to send incomplete HTTP request, which could make server keep waiting for the packet to finish the connection, until its resource exhausted. Then the web server is denial-of-service.

nodejs-trim-newlines: ReDoS in .end() method

The trim-newlines package before 3.0.1 and 4.x before 4.0.1 for Node.js has an issue related to regular expression denial-of-service (ReDoS) for the .end() method.

Denial of service in DataCommunicator class in Vaadin 8

Missing check in DataCommunicator class in com.vaadin:vaadin-server versions 8.0.0 through 8.14.0 (Vaadin 8.0.0 through 8.14.0) allows authenticated network attacker to cause heap exhaustion by requesting too many rows of data.

nodejs-css-what: does not ensure that attribute parsing has linear time complexity relative to the size of the input

The css-what package 4.0.0 through 5.0.0 for Node.js does not ensure that attribute parsing has Linear Time Complexity relative to the size of the input.

cyrus-imapd: Denial of service via string hashing algorithm collisions

Cyrus IMAP before 3.4.2 allows remote attackers to cause a denial of service (multiple-minute daemon hang) via input that is mishandled during hash-table interaction. Because there are many insertions into a single bucket, strcmp becomes slow. This is fixed in 3.4.2, 3.2.8, and 3.0.16.

regex injection leading to DoS

User controlled `request.getHeader("Referer")`, `request.getRequestURL()` and `request.getQueryString()` are used to build and run a regex expression. The attacker doesn't have to use a browser and may send a specially crafted Referer header programmatically. Since the attacker controls the string and the regex pattern he may cause a ReDoS by regex catastrophic backtracking on the server side. This problem has been fixed in Roller 6.0.2.

python-urllib3: ReDoS in the parsing of authority part of URL

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.

nodejs-normalize-url: ReDoS for data URLs

The normalize-url package before 4.5.1, 5.x before 5.3.1, and 6.x before 6.0.1 for Node.js has a ReDoS (regular expression denial of service) issue because it has exponential performance for data: URLs.

Memory leak in the afra_box_read function in MP4Box in GPAC 1.0.1 allows attackers to read memory via a crafted file.

golang: math/big.Rat: may cause a panic or an unrecoverable fatal error if passed inputs with very large exponents

In Go before 1.15.13 and 1.16.x before 1.16.5, there can be a panic for a large exponent to the math/big.Rat SetString or UnmarshalText method.
