| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2020-09-25 | CVE-2020-24718 | Missing Authorization vulnerability in multiple products bhyve, as used in FreeBSD through 12.1 and illumos (e.g., OmniOS CE through r151034 and OpenIndiana through Hipster 2020.04), does not properly restrict VMCS and VMCB read/write operations, as demonstrated by a root user in a container on an Intel system, who can gain privileges by modifying VMCS_HOST_RIP. | 8.2 |
| 2020-08-06 | CVE-2020-7460 | Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Freebsd 11.3/11.4/12.1 In FreeBSD 12.1-STABLE before r363918, 12.1-RELEASE before p8, 11.4-STABLE before r363919, 11.4-RELEASE before p2, and 11.3-RELEASE before p12, the sendmsg system call in the compat32 subsystem on 64-bit platforms has a time-of-check to time-of-use vulnerability allowing a mailcious userspace program to modify control message headers after they were validation. | 7.0 |
| 2020-07-09 | CVE-2020-7457 | Improper Synchronization vulnerability in Freebsd 11.3/11.4/12.1 In FreeBSD 12.1-STABLE before r359565, 12.1-RELEASE before p7, 11.4-STABLE before r362975, 11.4-RELEASE before p1, and 11.3-RELEASE before p11, missing synchronization in the IPV6_2292PKTOPTIONS socket option set handler contained a race condition allowing a malicious application to modify memory after being freed, possibly resulting in code execution. | 8.1 |
| 2020-05-13 | CVE-2019-15879 | Missing Release of Resource after Effective Lifetime vulnerability in Freebsd 11.3/12.1 In FreeBSD 12.1-STABLE before r356908, 12.1-RELEASE before p5, 11.3-STABLE before r356908, and 11.3-RELEASE before p9, a race condition in the cryptodev module permitted a data structure in the kernel to be used after it was freed, allowing an unprivileged process can overwrite arbitrary kernel memory. | 7.4 |
| 2020-05-13 | CVE-2019-15878 | Use After Free vulnerability in Freebsd 11.3/12.1 In FreeBSD 12.1-STABLE before r352509, 11.3-STABLE before r352509, and 11.3-RELEASE before p9, an unprivileged local user can trigger a use-after-free situation due to improper checking in SCTP when an application tries to update an SCTP-AUTH shared key. | 7.8 |
| 2020-04-21 | CVE-2020-1967 | NULL Pointer Dereference vulnerability in multiple products Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. | 7.5 |
| 2020-03-14 | CVE-2020-10566 | Classic Buffer Overflow vulnerability in Freebsd grub2-bhyve, as used in FreeBSD bhyve before revision 525916 2020-02-12, mishandles font loading by a guest through a grub2.cfg file, leading to a buffer overflow. | 7.8 |
| 2020-03-14 | CVE-2020-10565 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Freebsd grub2-bhyve, as used in FreeBSD bhyve before revision 525916 2020-02-12, does not validate the address provided as part of a memrw command (read_* or write_*) by a guest through a grub2.cfg file. | 7.8 |
| 2020-02-20 | CVE-2012-5365 | Resource Exhaustion vulnerability in multiple products The IPv6 implementation in FreeBSD and NetBSD (unknown versions, year 2012 and earlier) allows remote attackers to cause a denial of service via a flood of ICMPv6 Router Advertisement packets containing multiple Routing entries. | 7.5 |
| 2020-02-20 | CVE-2012-5363 | Resource Exhaustion vulnerability in multiple products The IPv6 implementation in FreeBSD and NetBSD (unknown versions, year 2012 and earlier) allows remote attackers to cause a denial of service via a flood of ICMPv6 Neighbor Solicitation messages, a different vulnerability than CVE-2011-2393. | 7.5 |
