| CVE-2021-43854 | 1 Nltk | 1 Nltk | 2022-01-04 | 5.0 MEDIUM | 7.5 HIGH |
| NLTK (Natural Language Toolkit) is a suite of open source Python modules, data sets, and tutorials supporting research and development in Natural Language Processing. Versions prior to 3.6.5 are vulnerable to regular expression denial of service (ReDoS) attacks. The vulnerability is present in PunktSentenceTokenizer, sent_tokenize and word_tokenize. Any users of this class, or these two functions, are vulnerable to the ReDoS attack. In short, a specifically crafted long input to any of these vulnerable functions will cause them to take a significant amount of execution time. If your program relies on any of the vulnerable functions for tokenizing unpredictable user input, then we would strongly recommend upgrading to a version of NLTK without the vulnerability. For users unable to upgrade the execution time can be bounded by limiting the maximum length of an input to any of the vulnerable functions. Our recommendation is to implement such a limit. | |||||

| CVE-2021-43843 | 1 Jsx-slack Project | 1 Jsx-slack | 2022-01-03 | 5.0 MEDIUM | 7.5 HIGH |
| jsx-slack is a package for building JSON objects for Slack block kit surfaces from JSX. The maintainers found the patch for CVE-2021-43838 in jsx-slack v4.5.1 is insufficient tfor protection from a Regular Expression Denial of Service (ReDoS) attack. If an attacker can put a lot of JSX elements into `<blockquote>` tag _with including multibyte characters_, an internal regular expression for escaping characters may consume an excessive amount of computing resources. v4.5.1 passes the test against ASCII characters but misses the case of multibyte characters. jsx-slack v4.5.2 has updated regular expressions for escaping blockquote characters to prevent catastrophic backtracking. It is also including an updated test case to confirm rendering multiple tags in `<blockquote>` with multibyte characters. | |||||

This increases the size of the log file on the remote server until memory is exhausted, therefore consuming the maximum amount of resources (triggering a denial of service condition). | |||||
| CVE-2021-39171 | 1 Passport-saml Project | 1 Passport-saml | 2021-09-07 | 5.0 MEDIUM | 7.5 HIGH |
| Passport-SAML is a SAML 2.0 authentication provider for Passport, the Node.js authentication library. Prior to version 3.1.0, a malicious SAML payload can require transforms that consume significant system resources to process, thereby resulting in reduced or denied service. This would be an effective way to perform a denial-of-service attack. This has been resolved in version 3.1.0. The resolution is to limit the number of allowable transforms to 2. | |||||
| CVE-2021-33580 | 1 Apache | 1 Roller | 2021-08-26 | 4.3 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2021-25659 | 1 Siemens | 1 Automation License Manager | 2021-08-18 | 5.0 MEDIUM | 7.5 HIGH |
| A vulnerability has been identified in Automation License Manager 5 (All versions), Automation License Manager 6 (All versions < V6.0 SP9 Update 2). Sending specially crafted packets to port 4410/tcp of an affected system could lead to extensive memory being consumed and as such could cause a denial-of-service preventing legitimate users from using the system. | |||||
| CVE-2021-22124 | 1 Fortinet | 2 Fortiauthenticator, Fortisandbox | 2021-08-12 | 7.8 HIGH | 7.5 HIGH |
| An uncontrolled resource consumption (denial of service) vulnerability in the login modules of FortiSandbox 3.2.0 through 3.2.2, 3.1.0 through 3.1.4, and 3.0.0 through 3.0.6; and FortiAuthenticator before 6.0.6 may allow an unauthenticated attacker to bring the device into an unresponsive state via specifically-crafted long request parameters. | |||||
| CVE-2018-1000115 | 4 Canonical, Debian, Memcached and 1 more | 4 Ubuntu Linux, Debian Linux, Memcached and 1 more | 2021-08-04 | 5.0 MEDIUM | 7.5 HIGH |
| Memcached version 1.5.5 contains an Insufficient Control of Network Message Volume (Network Amplification, CWE-406) vulnerability in the UDP support of the memcached server that can result in denial of service via network flood (traffic amplification of 1:50,000 has been reported by reliable sources). This attack appear to be exploitable via network connectivity to port 11211 UDP. This vulnerability appears to have been fixed in 1.5.6 due to the disabling of the UDP protocol by default. | |||||

| In Wireshark 3.2.0 to 3.2.3, 3.0.0 to 3.0.10, and 2.6.0 to 2.6.16, the NFS dissector could crash. This was addressed in epan/dissectors/packet-nfs.c by preventing excessive recursion, such as for a cycle in the directory graph on a filesystem. | |||||
| CVE-2020-28030 | 3 Debian, Fedoraproject, Wireshark | 3 Debian Linux, Fedora, Wireshark | 2021-07-21 | 5.0 MEDIUM | 7.5 HIGH |
| In Wireshark 3.2.0 to 3.2.7, the GQUIC dissector could crash. This was addressed in epan/dissectors/packet-gquic.c by correcting the implementation of offset advancement. | |||||
| CVE-2020-11996 | 6 Apache, Canonical, Debian and 3 more | 8 Tomcat, Ubuntu Linux, Debian Linux and 5 more | 2021-07-21 | 5.0 MEDIUM | 7.5 HIGH |
| A specially crafted sequence of HTTP/2 requests sent to Apache Tomcat 10.0.0-M1 to 10.0.0-M5, 9.0.0.M1 to 9.0.35 and 8.5.0 to 8.5.55 could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive. | |||||
