| CVE-2021-41167 | 1 Modern-async Project | 1 Modern-async | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| modern-async is an open source JavaScript tooling library for asynchronous operations using async/await and promises. In affected versions a bug affecting two of the functions in this library: forEachSeries and forEachLimit. They should limit the concurrency of some actions but, in practice, they don't. Any code calling these functions will be written thinking they would limit the concurrency but they won't. This could lead to potential security issues in other projects. The problem has been patched in 1.0.4. There is no workaround. | |||||
| CVE-2021-41145 | 1 Freeswitch | 1 Freeswitch | 2024-11-21 | 5.0 MEDIUM | 8.6 HIGH |
| FreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a software implementation that runs on any commodity hardware. FreeSWITCH prior to version 1.10.7 is susceptible to Denial of Service via SIP flooding. When flooding FreeSWITCH with SIP messages, it was observed that after a number of seconds the process was killed by the operating system due to memory exhaustion. By abusing this vulnerability, an attacker is able to crash any FreeSWITCH instance by flooding it with SIP messages, leading to Denial of Service. The attack does not require authentication and can be carried out over UDP, TCP or TLS. This issue was patched in version 1.10.7. | |||||
| CVE-2021-41119 | 1 Wire | 1 Wire-server | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| Wire-server is the system server for the wire back-end services. Releases prior to v2022-03-01 are subject to a denial of service attack via a crafted object causing a hash collision. This collision causes the server to spend at least quadratic time parsing it which can lead to a denial of service for a heavily used server. The issue has been fixed in wire-server 2022-03-01 and is already deployed on all Wire managed services. On premise instances of wire-server need to be updated to 2022-03-01, so that their backends are no longer affected. There are no known workarounds for this issue. | |||||
| CVE-2021-41118 | 1 Dynamicpagelist3 Project | 1 Dynamicpagelist3 | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| The DynamicPageList3 extension is a reporting tool for MediaWiki, listing category members and intersections with various formats and details. In affected versions unsanitised input of regular expression date within the parameters of the DPL parser function, allowed for the possibility of ReDoS (Regex Denial of Service). This has been resolved in version 3.3.6. If you are unable to update you may also set `$wgDplSettings['functionalRichness'] = 0;` or disable DynamicPageList3 to mitigate. | |||||
| CVE-2021-41115 | 1 Zulip | 1 Zulip | 2024-11-21 | 4.0 MEDIUM | 4.3 MEDIUM |
| Zulip is an open source team chat server. In affected versions Zulip allows organization administrators on a server to configure "linkifiers" that automatically create links from messages that users send, detected via arbitrary regular expressions. Malicious organization administrators could subject the server to a denial-of-service via regular expression complexity attacks; most simply, by configuring a quadratic-time regular expression in a linkifier, and sending messages that exploited it. A regular expression attempted to parse the user-provided regexes to verify that they were safe from ReDoS -- this was both insufficient, as well as _itself_ subject to ReDoS if the organization administrator entered a sufficiently complex invalid regex. Affected users should [upgrade to the just-released Zulip 4.7](https://zulip.readthedocs.io/en/latest/production/upgrade-or-modify.html#upgrading-to-a-release), or [`main`](https://zulip.readthedocs.io/en/latest/production/upgrade-or-modify.html#upgrading-from-a-git-repository). | |||||
| CVE-2021-41014 | 1 Fortinet | 1 Fortiweb | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| A uncontrolled resource consumption in Fortinet FortiWeb version 6.4.1 and below, 6.3.15 and below allows an unauthenticated attacker to make the httpsd daemon unresponsive via huge HTTP packets | |||||
| CVE-2021-40406 | 1 Reolink | 2 Rlc-410w, Rlc-410w Firmware | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
| A denial of service vulnerability exists in the cgiserver.cgi session creation functionality of reolink RLC-410W v3.0.0.136_20121102. A specially-crafted HTTP request can lead to prevent users from logging in. An attacker can send an HTTP request to trigger this vulnerability. | |||||
| CVE-2021-40125 | 1 Cisco | 18 Adaptive Security Appliance Software, Asa 5505, Asa 5505 Firmware and 15 more | 2024-11-21 | 6.3 MEDIUM | 5.3 MEDIUM |
| A vulnerability in the Internet Key Exchange Version 2 (IKEv2) implementation of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to trigger a denial of service (DoS) condition on an affected device. This vulnerability is due to improper control of a resource. An attacker with the ability to spoof a trusted IKEv2 site-to-site VPN peer and in possession of valid IKEv2 credentials for that peer could exploit this vulnerability by sending malformed, authenticated IKEv2 messages to an affected device. A successful exploit could allow the attacker to trigger a reload of the device. | |||||
| CVE-2021-40117 | 1 Cisco | 19 Adaptive Security Appliance, Adaptive Security Appliance Software, Asa 5505 and 16 more | 2024-11-21 | 7.8 HIGH | 8.6 HIGH |
| A vulnerability in SSL/TLS message handler for Cisco Adaptive Security Appliance (ASA) Software and Cisco 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 exists because incoming SSL/TLS packets are not properly processed. An attacker could exploit this vulnerability by sending a crafted SSL/TLS packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. | |||||
| CVE-2021-40011 | 1 Huawei | 3 Emui, Harmonyos, Magic Ui | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| There is an uncontrolled resource consumption vulnerability in the display module. Successful exploitation of this vulnerability may affect integrity. | |||||
| CVE-2021-3912 | 2 Cloudflare, Debian | 2 Octorpki, Debian Linux | 2024-11-21 | 4.3 MEDIUM | 4.2 MEDIUM |
| OctoRPKI tries to load the entire contents of a repository in memory, and in the case of a GZIP bomb, unzip it in memory, making it possible to create a repository that makes OctoRPKI run out of memory (and thus crash). | |||||
| CVE-2021-3909 | 2 Cloudflare, Debian | 2 Octorpki, Debian Linux | 2024-11-21 | 5.0 MEDIUM | 4.4 MEDIUM |
| OctoRPKI does not limit the length of a connection, allowing for a slowloris DOS attack to take place which makes OctoRPKI wait forever. Specifically, the repository that OctoRPKI sends HTTP requests to will keep the connection open for a day before a response is returned, but does keep drip feeding new bytes to keep the connection alive. | |||||
| CVE-2021-3908 | 2 Cloudflare, Debian | 2 Octorpki, Debian Linux | 2024-11-21 | 5.0 MEDIUM | 5.9 MEDIUM |
| OctoRPKI does not limit the depth of a certificate chain, allowing for a CA to create children in an ad-hoc fashion, thereby making tree traversal never end. | |||||
| CVE-2021-3822 | 1 Jsoneditoronline | 1 Jsoneditor | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| jsoneditor is vulnerable to Inefficient Regular Expression Complexity | |||||
| CVE-2021-3764 | 1 Linux | 1 Linux Kernel | 2024-11-21 | N/A | 5.5 MEDIUM |
| A memory leak flaw was found in the Linux kernel's ccp_run_aes_gcm_cmd() function that allows an attacker to cause a denial of service. The vulnerability is similar to the older CVE-2019-18808. The highest threat from this vulnerability is to system availability. | |||||

| A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2021-3733 | 4 Fedoraproject, Netapp, Python and 1 more | 20 Extra Packages For Enterprise Linux, Fedora, Hci Compute Node Firmware and 17 more | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability. | |||||
