|---|---|---|---|
| 2021-03-26 | CVE-2020-7461 | Out-of-bounds Write vulnerability in multiple products In FreeBSD 12.1-STABLE before r365010, 11.4-STABLE before r365011, 12.1-RELEASE before p9, 11.4-RELEASE before p3, and 11.3-RELEASE before p13, dhclient(8) fails to handle certain malformed input related to handling of DHCP option 119 resulting a heap overflow. | 7.3 |
| 2021-03-26 | CVE-2020-25582 | Race Condition vulnerability in Freebsd 11.4/12.2 In FreeBSD 12.2-STABLE before r369334, 11.4-STABLE before r369335, 12.2-RELEASE before p4 and 11.4-RELEASE before p8 when a process, such as jexec(8) or killall(1), calls jail_attach(2) to enter a jail, the jailed root can attach to it using ptrace(2) before the current working directory is changed. | 8.7 |
| 2021-03-26 | CVE-2020-25581 | Race Condition vulnerability in Freebsd 11.4/12.2 In FreeBSD 12.2-STABLE before r369312, 11.4-STABLE before r369313, 12.2-RELEASE before p4 and 11.4-RELEASE before p8 due to a race condition in the jail_remove(2) implementation, it may fail to kill some of the processes. | 7.5 |
| 2021-03-25 | CVE-2021-3450 | Improper Certificate Validation vulnerability in multiple products The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. | 7.4 |
| 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 |
