CVE-2021-41115 1 Zulip 1 Zulip 2024-11-21 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-2021-41079 4 Apache, Debian, Netapp and 1 more 6 Tomcat, Debian Linux, Management Services For Element Software And Netapp Hci and 3 more 2024-11-21 7.5 High
Apache Tomcat 8.5.0 to 8.5.63, 9.0.0-M1 to 9.0.43 and 10.0.0-M1 to 10.0.2 did not properly validate incoming TLS packets. When Tomcat was configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially crafted packet could be used to trigger an infinite loop resulting in a denial of service.
CVE-2021-41014 1 Fortinet 1 Fortiweb 2024-11-21 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-2021-40833 3 Apple, F-secure, Microsoft 7 Macos, Atlant, Elements Endpoint Protection and 4 more 2024-11-21 5.5 Medium
A vulnerability affecting F-Secure antivirus engine was discovered whereby unpacking UPX file can lead to denial-of-service. The vulnerability can be exploited remotely by an attacker. A successful attack will result in denial-of-service of the antivirus engine.
CVE-2021-40633 1 Giflib Project 1 Giflib 2024-11-21 8.8 High
A memory leak (out-of-memory) in gif2rgb in util/gif2rgb.c in giflib 5.1.4 allows remote attackers trigger an out of memory exception or denial of service via a gif format file.
CVE-2021-40546 1 Tenda 2 Ac6, Ac6 Firmware 2024-11-21 4.9 Medium
Tenda AC6 US_AC6V4.0RTL_V02.03.01.26_cn.bin allows attackers (who have the administrator password) to cause a denial of service (device crash) via a long string in the wifiPwd_5G parameter to /goform/setWifi.
CVE-2021-40125 1 Cisco 18 Adaptive Security Appliance Software, Asa 5505, Asa 5505 Firmware and 15 more 2024-11-21 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-2021-40122 1 Cisco 1 Meeting Server 2024-11-21 5.9 Medium
A vulnerability in an API of the Call Bridge feature of Cisco Meeting Server could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper handling of large series of message requests. An attacker could exploit this vulnerability by sending a series of messages to the vulnerable API. A successful exploit could allow the attacker to cause the affected device to reload, dropping all ongoing calls and resulting in a DoS condition.
CVE-2021-40117 1 Cisco 19 Adaptive Security Appliance, Adaptive Security Appliance Software, Asa 5505 and 16 more 2024-11-21 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-2021-40047 1 Huawei 3 Emui, Harmonyos, Magic Ui 2024-11-21 7.5 High
There is a vulnerability of memory not being released after effective lifetime in the Bastet module. Successful exploitation of this vulnerability may affect integrity.
CVE-2021-40011 1 Huawei 3 Emui, Harmonyos, Magic Ui 2024-11-21 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 4.2 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 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 5.9 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-2021-3905 4 Canonical, Fedoraproject, Openvswitch and 1 more 5 Ubuntu Linux, Fedora, Openvswitch and 2 more 2024-11-21 7.5 High
A memory leak was found in Open vSwitch (OVS) during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments.
