CVE-2007-6059 1 Sun 1 Javamail 2026-04-23 N/A
Javamail does not properly handle a series of invalid login attempts in which the same e-mail address is entered as username and password, and the domain portion of this address yields a Java UnknownHostException error, which allows remote attackers to cause a denial of service (connection pool exhaustion) via a large number of requests, resulting in a SQLNestedException. NOTE: Sun disputes this issue, stating "The report makes references to source code and files that do not exist in the mentioned products.
CVE-2017-12232 1 Cisco 130 1000 Integrated Services Router, 1100-4g\/6g Integrated Services Router, 1100-4g Integrated Services Router and 127 more 2026-04-22 6.5 Medium
A vulnerability in the implementation of a protocol in Cisco Integrated Services Routers Generation 2 (ISR G2) Routers running Cisco IOS 15.0 through 15.6 could allow an unauthenticated, adjacent attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to a misclassification of Ethernet frames. An attacker could exploit this vulnerability by sending a crafted Ethernet frame to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Cisco Bug IDs: CSCvc03809.
CVE-2017-6627 1 Cisco 2 Ios, Ios Xe 2026-04-22 7.5 High
A vulnerability in the UDP processing code of Cisco IOS 15.1, 15.2, and 15.4 and IOS XE 3.14 through 3.18 could allow an unauthenticated, remote attacker to cause the input queue of an affected system to hold UDP packets, causing an interface queue wedge and a denial of service (DoS) condition. The vulnerability is due to Cisco IOS Software application changes that create UDP sockets and leave the sockets idle without closing them. An attacker could exploit this vulnerability by sending UDP packets with a destination port of 0 to an affected device. A successful exploit could allow the attacker to cause UDP packets to be held in the input interfaces queue, resulting in a DoS condition. The input interface queue will stop holding UDP packets when it receives 250 packets. Cisco Bug IDs: CSCup10024, CSCva55744, CSCva95506.
CVE-2017-12237 1 Cisco 301 1000 Integrated Services Router, 1100-4g\/6g Integrated Services Router, 1100-4g Integrated Services Router and 298 more 2026-04-21 7.5 High
A vulnerability in the Internet Key Exchange Version 2 (IKEv2) module of Cisco IOS 15.0 through 15.6 and Cisco IOS XE 3.5 through 16.5 could allow an unauthenticated, remote attacker to cause high CPU utilization, traceback messages, or a reload of an affected device that leads to a denial of service (DoS) condition. The vulnerability is due to how an affected device processes certain IKEv2 packets. An attacker could exploit this vulnerability by sending specific IKEv2 packets to an affected device to be processed. A successful exploit could allow the attacker to cause high CPU utilization, traceback messages, or a reload of the affected device that leads to a DoS condition. This vulnerability affects Cisco devices that have the Internet Security Association and Key Management Protocol (ISAKMP) enabled. Although only IKEv2 packets can be used to trigger this vulnerability, devices that are running Cisco IOS Software or Cisco IOS XE Software are vulnerable when ISAKMP is enabled. A device does not need to be configured with any IKEv2-specific features to be vulnerable. Many features use IKEv2, including different types of VPNs such as the following: LAN-to-LAN VPN; Remote-access VPN, excluding SSL VPN; Dynamic Multipoint VPN (DMVPN); and FlexVPN. Cisco Bug IDs: CSCvc41277.
CVE-2017-12238 1 Cisco 20 C6800-16p10g, C6800-16p10g-xl, Catalyst 6000 and 17 more 2026-04-21 6.5 Medium
A vulnerability in the Virtual Private LAN Service (VPLS) code of Cisco IOS 15.0 through 15.4 for Cisco Catalyst 6800 Series Switches could allow an unauthenticated, adjacent attacker to cause a C6800-16P10G or C6800-16P10G-XL type line card to crash, resulting in a denial of service (DoS) condition. The vulnerability is due to a memory management issue in the affected software. An attacker could exploit this vulnerability by creating a large number of VPLS-generated MAC entries in the MAC address table of an affected device. A successful exploit could allow the attacker to cause a C6800-16P10G or C6800-16P10G-XL type line card to crash, resulting in a DoS condition. This vulnerability affects Cisco Catalyst 6800 Series Switches that are running a vulnerable release of Cisco IOS Software and have a Cisco C6800-16P10G or C6800-16P10G-XL line card in use with Supervisor Engine 6T. To be vulnerable, the device must also be configured with VPLS and the C6800-16P10G or C6800-16P10G-XL line card needs to be the core-facing MPLS interfaces. Cisco Bug IDs: CSCva61927.
CVE-2017-12231 1 Cisco 329 1100-4g\/6g Integrated Services Router, 1100-4g Integrated Services Router, 1100-4gltegb Integrated Services Router and 326 more 2026-04-21 7.5 High
A vulnerability in the implementation of Network Address Translation (NAT) functionality in Cisco IOS 12.4 through 15.6 could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to the improper translation of H.323 messages that use the Registration, Admission, and Status (RAS) protocol and are sent to an affected device via IPv4 packets. An attacker could exploit this vulnerability by sending a crafted H.323 RAS packet through an affected device. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition. This vulnerability affects Cisco devices that are configured to use an application layer gateway with NAT (NAT ALG) for H.323 RAS messages. By default, a NAT ALG is enabled for H.323 RAS messages. Cisco Bug IDs: CSCvc57217.
CVE-2026-23027 1 Linux 1 Linux Kernel 2026-04-18 N/A
In the Linux kernel, the following vulnerability has been resolved: LoongArch: KVM: Fix kvm_device leak in kvm_pch_pic_destroy() In kvm_ioctl_create_device(), kvm_device has allocated memory, kvm_device->destroy() seems to be supposed to free its kvm_device struct, but kvm_pch_pic_destroy() is not currently doing this, that would lead to a memory leak. So, fix it.
CVE-2006-0749 2 Mozilla, Redhat 5 Firefox, Mozilla Suite, Seamonkey and 2 more 2026-04-16 N/A
nsHTMLContentSink.cpp in Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors involving a "particular sequence of HTML tags" that leads to memory corruption.
CVE-2006-1991 1 Php 1 Php 2026-04-16 N/A
