Linux kernel 安全漏洞
Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that originates in the pppasyncencode function that assumes LCP packets are valid without checking the actual contents of th...
The vulnerability of the BIND DNS server, related to uncontrolled resource consumption, allows a hacker to cause a service failure.
The vulnerability of the BIND DNS server is related to uncontrolled resource consumption. Exploiting this vulnerability allows a malicious actor to cause service failures by sending a large number of DNS requests via the TCP protocol...
kernel: tcp: Use refcount_inc_not_zero() in tcp_twsk_unique().
A use-after-free flaw was found in the Linux kernel’s TCP protocol in how a local user triggers a complex race condition during connection to the socket. This flaw allows a local user to crash or potentially escalate their privileges on the system...
ISC BIND 安全漏洞
ISC BIND is an ISC open source suite of open source software that implements the DNS protocol. A security vulnerability exists in ISC BIND 9, which stems from the fact that a large number of DNS messages on TCP may destabilize the server...
The vulnerability of the Control Protocol Director (l2cpd) in Juniper Networks’ Junos OS and Junos OS Evolved operating systems allows a attacker to cause a service failure.
The vulnerability of the Control Protocol Director l2cpd in Juniper Networks’ Junos OS and Junos OS Evolved operating systems is related to improper handling of exceptional states. Exploiting this vulnerability can allow a malicious actor to cause service interruptions...
UBUNTU-CVE-2024-0760
A malicious client can send many DNS messages over TCP, potentially causing the server to become unstable while the attack is in progress. The server may recover after the attack ceases. Use of ACLs will not mitigate the attack. This issue affects BIND 9 versions 9.18.1 through 9.18.27, 9.19.0...
