| CVE-2021-34737 | 1 Cisco | 37 Asr 9000v-v2, Asr 9001, Asr 9006 and 34 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| A vulnerability in the DHCP version 4 (DHCPv4) server feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to trigger a crash of the dhcpd process, resulting in a denial of service (DoS) condition. This vulnerability exists because certain DHCPv4 messages are improperly validated when they are processed by an affected device. An attacker could exploit this vulnerability by sending a malformed DHCPv4 message to an affected device. A successful exploit could allow the attacker to cause a NULL pointer dereference, resulting in a crash of the dhcpd process. While the dhcpd process is restarting, which may take up to approximately two minutes, DHCPv4 server services are unavailable on the affected device. This could temporarily prevent network access to clients that join the network during that time period. Note: Only the dhcpd process crashes and eventually restarts automatically. The router does not reload. | |||||
| CVE-2021-34555 | 2 Fedoraproject, Trusteddomain | 2 Fedora, Opendmarc | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| OpenDMARC 1.4.1 and 1.4.1.1 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a multi-value From header field. | |||||
| CVE-2021-31826 | 1 Shibboleth | 1 Service Provider | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| Shibboleth Service Provider 3.x before 3.2.2 is prone to a NULL pointer dereference flaw involving the session recovery feature. The flaw is exploitable (for a daemon crash) on systems not using this feature if a crafted cookie is supplied. | |||||
| CVE-2021-30178 | 2 Fedoraproject, Linux | 2 Fedora, Linux Kernel | 2023-11-07 | 2.1 LOW | 5.5 MEDIUM |
| An issue was discovered in the Linux kernel through 5.11.11. synic_get in arch/x86/kvm/hyperv.c has a NULL pointer dereference for certain accesses to the SynIC Hyper-V context, aka CID-919f4ebc5987. | |||||
| CVE-2021-28543 | 2 Fedoraproject, Varnish-cache | 3 Fedora, Varnish-modules, Varnish-modules Klarlack | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| Varnish varnish-modules before 0.17.1 allows remote attackers to cause a denial of service (daemon restart) in some configurations. This does not affect organizations that only install the Varnish Cache product; however, it is common to install both Varnish Cache and varnish-modules. Specifically, an assertion failure or NULL pointer dereference can be triggered in Varnish Cache through the varnish-modules header.append() and header.copy() functions. For some Varnish Configuration Language (VCL) files, this gives remote clients an opportunity to cause a Varnish Cache restart. A restart reduces overall availability and performance due to an increased number of cache misses, and may cause higher load on backend servers. | |||||
| CVE-2021-27836 | 2 Fedoraproject, Libxls Project | 2 Fedora, Libxls | 2023-11-07 | 4.3 MEDIUM | 6.5 MEDIUM |
