CVE-2020-7461 | 2 Freebsd, Siemens | 5 Freebsd, Simatic Rf350m, Simatic Rf350m Firmware and 2 more | 2024-11-21 | 7.3 High |
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.

CVE-2020-7455 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 5.5 Medium |
In FreeBSD 12.1-STABLE before r360973, 12.1-RELEASE before p5, 11.4-STABLE before r360973, 11.4-BETA1 before p1 and 11.3-RELEASE before p9, the FTP packet handler in libalias incorrectly calculates some packet length allowing disclosure of small amounts of kernel (for kernel NAT) or natd process space (for userspace natd). | ||||
CVE-2020-7454 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 9.8 Critical |
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. | ||||
CVE-2020-7453 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 6.0 Medium |
In FreeBSD 12.1-STABLE before r359021, 12.1-RELEASE before 12.1-RELEASE-p3, 11.3-STABLE before r359020, and 11.3-RELEASE before 11.3-RELEASE-p7, a missing null termination check in the jail_set configuration option "osrelease" may return more bytes with a subsequent jail_get system call allowing a malicious jail superuser with permission to create nested jails to read kernel memory. | ||||

CVE-2020-25583 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 9.8 Critical |
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. rtsold(8) did not validate label lengths correctly and could overflow the destination buffer. | ||||
CVE-2020-25582 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 8.7 High |
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. | ||||
CVE-2020-25581 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 7.5 High |
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. | ||||
CVE-2020-25580 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 5.3 Medium |
In FreeBSD 12.2-STABLE before r369346, 11.4-STABLE before r369345, 12.2-RELEASE before p4 and 11.4-RELEASE before p8 a regression in the login.access(5) rule processor has the effect of causing rules to fail to match even when they should not. This means that rules denying access may be ignored. | ||||
CVE-2020-25579 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 5.3 Medium |
In FreeBSD 12.2-STABLE before r368969, 11.4-STABLE before r369047, 12.2-RELEASE before p3, 12.1-RELEASE before p13 and 11.4-RELEASE before p7 msdosfs(5) was failing to zero-fill a pair of padding fields in the dirent structure, resulting in a leak of three uninitialized bytes. | ||||
CVE-2020-25578 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 5.3 Medium |
In FreeBSD 12.2-STABLE before r368969, 11.4-STABLE before r369047, 12.2-RELEASE before p3, 12.1-RELEASE before p13 and 11.4-RELEASE before p7 several file systems were not properly initializing the d_off field of the dirent structures returned by VOP_READDIR. In particular, tmpfs(5), smbfs(5), autofs(5) and mqueuefs(5) were failing to do so. As a result, eight uninitialized kernel stack bytes may be leaked to userspace by these file systems. | ||||
CVE-2020-25577 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 9.8 Critical |
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. While the kernel currently ignores such malformed packets, it passes them to userspace programs. Any programs expecting the kernel to do validation may be vulnerable to an overflow. |
