Denial of service

On SRX Series devices, a crafted ICMP packet embedded within a NAT64 IPv6 to IPv4 tunnel may cause the flowd process to crash. Repeated crashes of the flowd process constitutes an extended denial of service condition for the SRX Series device. This issue only occurs if NAT64 is configured. Affect...

The DHCP client on D-Link DIR-850L REV. A with firmware through FW114WWb07h2abbeta1 and REV. B with firmware through FW208WWb02 devices allows unauthenticated remote code execution as root because /etc/services/INET/inetipv4.php mishandles shell metacharacters, affecting generated files such as...

Linux kernel denial of service vulnerability (CNVD-2017-24356)

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. A denial of service vulnerability exists in the net/ipv4/route.c file in Linux kernel versions 4.13-rc1 through 4.13-rc6. A local attacker can exploit this vulnerability to...

CVE-2017-13686

net/ipv4/route.c in the Linux kernel 4.13-rc1 through 4.13-rc6 is too late to check for a NULL fi field when RTMFFIBMATCH is set, which allows local users to cause a denial of service NULL pointer dereference or possibly have unspecified other impact via crafted system calls. NOTE: this does not...
