CVE-2021-43854 1 Nltk 1 Nltk 2024-11-21 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 2024-11-21 5.3 Medium
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.
CVE-2021-43838 1 Jsx-slack Project 1 Jsx-slack 2024-11-21 5.3 Medium
jsx-slack is a library for building JSON objects for Slack Block Kit surfaces from JSX. In versions prior to 4.5.1 users are vulnerable to a regular expression denial-of-service (ReDoS) attack. If attacker can put a lot of JSX elements into `<blockquote>` tag, an internal regular expression for escaping characters may consume an excessive amount of computing resources. jsx-slack v4.5.1 has patched to a regex for escaping blockquote characters. Users are advised to upgrade as soon as possible.
CVE-2021-43611 1 Linphone 1 Belle-sip 2024-11-21 7.5 High
Belledonne Belle-sip before 5.0.20 can crash applications such as Linphone via " \ " in the display name of a From header.
CVE-2021-43173 2 Debian, Nlnetlabs 2 Debian Linux, Routinator 2024-11-21 7.5 High
In NLnet Labs Routinator prior to 0.10.2, a validation run can be delayed significantly by an RRDP repository by not answering but slowly drip-feeding bytes to keep the connection alive. This can be used to effectively stall validation. While Routinator has a configurable time-out value for RRDP connections, this time-out was only applied to individual read or write operations rather than the complete request. Thus, if an RRDP repository sends a little bit of data before that time-out expired, it can continuously extend the time it takes for the request to finish. Since validation will only continue once the update of an RRDP repository has concluded, this delay will cause validation to stall, leading to Routinator continuing to serve the old data set or, if in the initial validation run directly after starting, never serve any data at all.
CVE-2021-42836 1 Gjson Project 1 Gjson 2024-11-21 7.5 High
GJSON before 1.9.3 allows a ReDoS (regular expression denial of service) attack.
CVE-2021-42523 1 Colord Project 1 Colord 2024-11-21 7.5 High
There are two Information Disclosure vulnerabilities in colord, and they lie in colord/src/cd-device-db.c and colord/src/cd-profile-db.c separately. They exist because the 'err_msg' of 'sqlite3_exec' is not releasing after use, while libxml2 emphasizes that the caller needs to release it.
CVE-2021-42522 1 Gnome 1 Anjuta 2024-11-21 7.5 High
There is a Information Disclosure vulnerability in anjuta/plugins/document-manager/anjuta-bookmarks.c. This issue was caused by the incorrect use of libxml2 API. The vendor forgot to call 'g_free()' to release the return value of 'xmlGetProp()'.
CVE-2021-42521 1 Vtk 1 Vtk 2024-11-21 7.5 High
There is a NULL pointer dereference vulnerability in VTK before 9.2.5, and it lies in IO/Infovis/vtkXMLTreeReader.cxx. The vendor didn't check the return value of libxml2 API 'xmlDocGetRootElement', and try to dereference it. It is unsafe as the return value can be NULL and that NULL pointer dereference may crash the application.
CVE-2021-42218 1 Rice 1 Open Motion Planning Library 2024-11-21 7.5 High
OMPL v1.5.2 contains a memory leak in VFRRT.cpp
CVE-2021-42197 1 Swftools 1 Swftools 2024-11-21 7.8 High
An issue was discovered in swftools through 20201222 through a memory leak in the swftools when swfdump is used. It allows an attacker to cause code execution.
CVE-2021-42120 1 Businessdnasolutions 1 Topease 2024-11-21 6.5 Medium
Insufficient Input Validation in Web Applications operating on Business-DNA Solutions GmbH’s TopEase® Platform Version <= 7.1.27 on all object attributes allows an authenticated remote attacker with Object Modification privileges to insert arbitrarily long strings, eventually leading to exhaustion of the underlying resource.
CVE-2021-41959 1 Jerryscript 1 Jerryscript 2024-11-21 7.5 High
JerryScript Git version 14ff5bf does not sufficiently track and release allocated memory via jerry-core/ecma/operations/ecma-regexp-object.c after RegExp, which causes a memory leak.
CVE-2021-41865 1 Hashicorp 1 Nomad 2024-11-21 6.5 Medium
HashiCorp Nomad and Nomad Enterprise 1.1.1 through 1.1.5 allowed authenticated users with job submission capabilities to cause denial of service by submitting incomplete job specifications with a Consul mesh gateway and host networking mode. Fixed in 1.1.6.
CVE-2021-41817 6 Debian, Fedoraproject, Opensuse and 3 more 12 Debian Linux, Fedora, Factory and 9 more 2024-11-21 7.5 High

CVE-2021-41800 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2024-11-21 5.3 Medium
MediaWiki before 1.36.2 allows a denial of service (resource consumption because of lengthy query processing time). Visiting Special:Contributions can sometimes result in a long running SQL query because PoolCounter protection is mishandled.
CVE-2021-41799 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2024-11-21 7.5 High
MediaWiki before 1.36.2 allows a denial of service (resource consumption because of lengthy query processing time). ApiQueryBacklinks (action=query&list=backlinks) can cause a full table scan.

A vulnerability has been identified in RUGGEDCOM ROX MX5000 (All versions < V2.14.1), RUGGEDCOM ROX RX1400 (All versions < V2.14.1), RUGGEDCOM ROX RX1500 (All versions < V2.14.1), RUGGEDCOM ROX RX1501 (All versions < V2.14.1), RUGGEDCOM ROX RX1510 (All versions < V2.14.1), RUGGEDCOM ROX RX1511 (All versions < V2.14.1), RUGGEDCOM ROX RX1512 (All versions < V2.14.1), RUGGEDCOM ROX RX1524 (All versions < V2.14.1), RUGGEDCOM ROX RX1536 (All versions < V2.14.1), RUGGEDCOM ROX RX5000 (All versions < V2.14.1). Affected devices write crashdumps without checking if enough space is available on the filesystem. Once the crashdump fills the entire root filesystem, affected devices fail to boot successfully. An attacker can leverage this vulnerability to cause a permanent Denial-of-Service.
CVE-2021-41490 1 Rice 1 Open Motion Planning Library 2024-11-21 7.5 High
Memory leaks in LazyPRM.cpp of OMPL v1.5.0 can cause unexpected behavior.
CVE-2021-41441 1 Dlink 2 Dir-x1860, Dir-x1860 Firmware 2024-11-21 7.4 High
A DoS attack in the web application of D-Link DIR-X1860 before v1.10WWB09_Beta allows a remote unauthenticated attacker to reboot the router via sending a specially crafted URL to an authenticated victim. The authenticated victim need to visit this URL, for the router to reboot.
