| CVE-2020-1749 | Hig | 0.49 | 7.5 | 0.01 | Sep 9, 2020 | A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather… | ||
| CVE-2020-11868 | Hig | 0.49 | 7.5 | 0.02 | Apr 17, 2020 | ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp. | ||
| CVE-2013-4166 | Hig | 0.49 | 7.5 | 0.02 | Feb 6, 2020 | The gpg_ctx_add_recipient function in camel/camel-gpg-context.c in GNOME Evolution 3.8.4 and earlier and Evolution Data Server 3.9.5 and earlier does not properly select the GPG key to use for email encryption, which might cause the email to be encrypted with the wrong key and… |
