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.
CVE-2020-24863 2 Freebsd, Midnightbsd 2 Freebsd, Midnightbsd 2024-11-21 5.5 Medium
A memory corruption vulnerability was found in the kernel function kern_getfsstat in MidnightBSD before 1.2.7 and 1.3 through 2020-08-19, and FreeBSD through 11.4, that allows an attacker to trigger an invalid free and crash the system via a crafted size value in conjunction with an invalid mode.
CVE-2020-24718 4 Freebsd, Netapp, Omniosce and 1 more 4 Freebsd, Clustered Data Ontap, Omnios and 1 more 2024-11-21 8.2 High
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.
CVE-2020-24717 2 Freebsd, Openzfs 2 Freebsd, Openzfs 2024-11-21 7.8 High
OpenZFS before 2.0.0-rc1, when used on FreeBSD, misinterprets group permissions as user permissions, as demonstrated by mode 0770 being equivalent to mode 0777.
CVE-2020-24716 2 Freebsd, Openzfs 2 Freebsd, Openzfs 2024-11-21 7.8 High
OpenZFS before 2.0.0-rc1, when used on FreeBSD, allows execute permissions for all directories.
CVE-2020-24385 2 Freebsd, Midnightbsd 2 Freebsd, Midnightbsd 2024-11-21 5.5 Medium
In MidnightBSD before 1.2.6 and 1.3 before August 2020, and FreeBSD before 7, a NULL pointer dereference was found in the Linux emulation layer that allows attackers to crash the running kernel. During binary interaction, td->td_emuldata in sys/compat/linux/linux_emul.h is not getting initialized and returns NULL from em_find().
CVE-2020-1967 10 Broadcom, Debian, Fedoraproject and 7 more 26 Fabric Operating System, Debian Linux, Fedora and 23 more 2024-11-21 7.5 High
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. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. Fixed in OpenSSL 1.1.1g (Affected 1.1.1d-1.1.1f).
CVE-2020-13434 8 Apple, Canonical, Debian and 5 more 16 Icloud, Ipados, Iphone Os and 13 more 2024-11-21 5.5 Medium
SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c.
CVE-2020-13160 3 Anydesk, Freebsd, Linux 3 Anydesk, Freebsd, Linux Kernel 2024-11-21 9.8 Critical
AnyDesk before 5.5.3 on Linux and FreeBSD has a format string vulnerability that can be exploited for remote code execution.
CVE-2020-10566 1 Freebsd 1 Freebsd 2024-11-21 7.8 High
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.
CVE-2020-10565 1 Freebsd 1 Freebsd 2024-11-21 7.8 High
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. This allows an untrusted guest to perform arbitrary read or write operations in the context of the grub-bhyve process, resulting in code execution as root on the host OS.
CVE-2019-9499 6 Debian, Fedoraproject, Freebsd and 3 more 9 Debian Linux, Fedora, Freebsd and 6 more 2024-11-21 8.1 High
The implementations of EAP-PWD in wpa_supplicant EAP Peer, when built against a crypto library missing explicit validation on imported elements, do not validate the scalar and element values in EAP-pwd-Commit. An attacker may complete authentication, session key and control of the data connection with a client. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.4 are affected. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version 2.7 are affected.
CVE-2019-9498 6 Debian, Fedoraproject, Freebsd and 3 more 9 Debian Linux, Fedora, Freebsd and 6 more 2024-11-21 8.1 High
The implementations of EAP-PWD in hostapd EAP Server, when built against a crypto library missing explicit validation on imported elements, do not validate the scalar and element values in EAP-pwd-Commit. An attacker may be able to use invalid scalar/element values to complete authentication, gaining session key and network access without needing or learning the password. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.4 are affected. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version 2.7 are affected.
CVE-2019-9495 6 Debian, Fedoraproject, Freebsd and 3 more 9 Debian Linux, Fedora, Freebsd and 6 more 2024-11-21 3.7 Low
The implementations of EAP-PWD in hostapd and wpa_supplicant are vulnerable to side-channel attacks as a result of cache access patterns. All versions of hostapd and wpa_supplicant with EAP-PWD support are vulnerable. The ability to install and execute applications is necessary for a successful attack. Memory access patterns are visible in a shared cache. Weak passwords may be cracked. Versions of hostapd/wpa_supplicant 2.7 and newer, are not vulnerable to the timing attack described in CVE-2019-9494. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version 2.7 are affected.
