| CVE-2015-7973 | Med | 0.43 | 6.5 | 0.03 | Jan 30, 2017 | NTP before 4.2.8p6 and 4.3.x before 4.3.90, when configured in broadcast mode, allows man-in-the-middle attackers to conduct replay attacks by sniffing the network. | ||
| CVE-2016-1885 | Med | 0.43 | 6.2 | 0.01 | Apr 12, 2016 | Integer signedness error in the amd64_set_ldt function in sys/amd64/amd64/sys_machdep.c in FreeBSD 9.3 before p39, 10.1 before p31, and 10.2 before p14 allows local users to cause a denial of service (kernel panic) via an i386_set_ldt system call, which triggers a heap-based… | ||
| CVE-2026-45255 | Hig | 0.42 | 7.5 | 0.00 | May 21, 2026 | When bsdinstall or bsdconfig are prompted to scan for nearby Wi-Fi networks, they build up a list of network names and use bsddialog(1) to prompt the user to select a network. This is implemented using a shell script, and the code which handled network names was not careful to… | ||
| CVE-2026-45254 | Med | 0.42 | 6.5 | 0.00 | May 21, 2026 | In the case of the cap_net service, when a key present in the old limit was omitted from the new limit, the missing key was treated as "allow any" instead of being rejected. In certain scenarios, an application that had previously restricted a subset of network operations could… | ||
