| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-09-05 | CVE-2024-43102 | Use After Free vulnerability in Freebsd Concurrent removals of certain anonymous shared memory mappings by using the UMTX_SHM_DESTROY sub-request of UMTX_OP_SHM can lead to decreasing the reference count of the object representing the mapping too many times, causing it to be freed too early. A malicious code exercizing the UMTX_SHM_DESTROY sub-request in parallel can panic the kernel or enable further Use-After-Free attacks, potentially including code execution or Capsicum sandbox escape. | 10.0 |
| 2023-11-08 | CVE-2023-5941 | Incorrect Calculation of Buffer Size vulnerability in Freebsd In versions of FreeBSD 12.4-RELEASE prior to 12.4-RELEASE-p7 and FreeBSD 13.2-RELEASE prior to 13.2-RELEASE-p5 the __sflush() stdio function in libc does not correctly update FILE objects' write space members for write-buffered streams when the write(2) system call returns an error. | 9.8 |
| 2023-06-22 | CVE-2023-3326 | Improper Authentication vulnerability in Freebsd pam_krb5 authenticates a user by essentially running kinit with the password, getting a ticket-granting ticket (tgt) from the Kerberos KDC (Key Distribution Center) over the network, as a way to verify the password. | 9.8 |
| 2021-08-03 | CVE-2021-36159 | Out-of-bounds Read vulnerability in Freebsd Libfetch libfetch before 2021-07-26, as used in apk-tools, xbps, and other products, mishandles numeric strings for the FTP and HTTP protocols. | 9.1 |
| 2021-03-29 | CVE-2020-25583 | Classic Buffer Overflow vulnerability in Freebsd In FreeBSD 12.2-STABLE before r368250, 11.4-STABLE before r368253, 12.2-RELEASE before p1, 12.1-RELEASE before p11 and 11.4-RELEASE before p5 when processing a DNSSL option, rtsold(8) decodes domain name labels per an encoding specified in RFC 1035 in which the first octet of each label contains the label's length. | 9.8 |
| 2021-03-29 | CVE-2020-25577 | Classic Buffer Overflow vulnerability in Freebsd 11.4/12.1/12.2 In FreeBSD 12.2-STABLE before r368250, 11.4-STABLE before r368253, 12.2-RELEASE before p1, 12.1-RELEASE before p11 and 11.4-RELEASE before p5 rtsold(8) does not verify that the RDNSS option does not extend past the end of the received packet before processing its contents. | 9.8 |
| 2020-07-09 | CVE-2020-7458 | Out-of-bounds Write vulnerability in Freebsd 11.4/12.1 In FreeBSD 12.1-STABLE before r362281, 11.4-STABLE before r362281, and 11.4-RELEASE before p1, long values in the user-controlled PATH environment variable cause posix_spawnp to write beyond the end of the heap allocated stack possibly leading to arbitrary code execution. | 9.8 |
| 2020-05-13 | CVE-2020-7454 | Out-of-bounds Write vulnerability in Freebsd 11.3/11.4/12.1 In FreeBSD 12.1-STABLE before r360971, 12.1-RELEASE before p5, 11.4-STABLE before r360971, 11.4-BETA1 before p1 and 11.3-RELEASE before p9, libalias does not properly validate packet length resulting in modules causing an out of bounds read/write condition if no checking was built into the module. | 9.8 |
| 2020-05-13 | CVE-2019-15880 | Improper Input Validation vulnerability in Freebsd 12.1 In FreeBSD 12.1-STABLE before r356911, and 12.1-RELEASE before p5, insufficient checking in the cryptodev module allocated the size of a kernel buffer based on a user-supplied length allowing an unprivileged process to trigger a kernel panic. | 9.8 |
| 2020-04-29 | CVE-2020-7452 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Freebsd 11.3/12.1 In FreeBSD 12.1-STABLE before r357490, 12.1-RELEASE before 12.1-RELEASE-p3, 11.3-STABLE before r357489, and 11.3-RELEASE before 11.3-RELEASE-p7, incorrect use of a user-controlled pointer in the epair virtual network module allowed vnet jailed privileged users to panic the host system and potentially execute arbitrary code in the kernel. | 9.1 |
