| CVE-2020-16135 | 6 Canonical, Debian, Fedoraproject and 3 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2024-08-04 | 5.9 Medium |

| CVE-2020-14364 | 6 Canonical, Debian, Fedoraproject and 3 more | 14 Ubuntu Linux, Debian Linux, Fedora and 11 more | 2024-08-04 | 5.0 Medium |
| An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host. | ||||
| CVE-2020-14349 | 3 Opensuse, Postgresql, Redhat | 7 Leap, Postgresql, Enterprise Linux and 4 more | 2024-08-04 | 7.1 High |
| It was found that PostgreSQL versions before 12.4, before 11.9 and before 10.14 did not properly sanitize the search_path during logical replication. An authenticated attacker could use this flaw in an attack similar to CVE-2018-1058, in order to execute arbitrary SQL command in the context of the user used for replication. | ||||
| CVE-2020-14350 | 5 Canonical, Debian, Opensuse and 2 more | 9 Ubuntu Linux, Debian Linux, Leap and 6 more | 2024-08-04 | 7.3 High |
| It was found that some PostgreSQL extensions did not use search_path safely in their installation script. An attacker with sufficient privileges could use this flaw to trick an administrator into executing a specially crafted script, during the installation or update of such extension. This affects PostgreSQL versions before 12.4, before 11.9, before 10.14, before 9.6.19, and before 9.5.23. | ||||
| CVE-2020-10713 | 5 Debian, Gnu, Opensuse and 2 more | 10 Debian Linux, Grub2, Leap and 7 more | 2024-08-04 | 8.2 High |
| A flaw was found in grub2, prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel, an attacker would first need to establish access to the system such as gaining physical access, obtain the ability to alter a pxe-boot network, or have remote access to a networked system with root access. With this access, an attacker could then craft a string to cause a buffer overflow by injecting a malicious payload that leads to arbitrary code execution within GRUB. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2020-8203 | 3 Lodash, Oracle, Redhat | 24 Lodash, Banking Corporate Lending Process Management, Banking Credit Facilities Process Management and 21 more | 2024-08-04 | 7.4 High |
| Prototype pollution attack when using _.zipObjectDeep in lodash before 4.17.20. | ||||
| CVE-2020-1730 | 6 Canonical, Fedoraproject, Libssh and 3 more | 7 Ubuntu Linux, Fedora, Libssh and 4 more | 2024-08-04 | 5.3 Medium |
| A flaw was found in libssh versions before 0.8.9 and before 0.9.4 in the way it handled AES-CTR (or DES ciphers if enabled) ciphers. The server or client could crash when the connection hasn't been fully initialized and the system tries to cleanup the ciphers when closing the connection. The biggest threat from this vulnerability is system availability. | ||||
| CVE-2021-47099 | 1 Redhat | 3 Enterprise Linux, Rhel Eus, Rhev Hypervisor | 2024-08-04 | 6.0 Medium |
| In the Linux kernel, the following vulnerability has been resolved: veth: ensure skb entering GRO are not cloned. After commit d3256efd8e8b ("veth: allow enabling NAPI even without XDP"), if GRO is enabled on a veth device and TSO is disabled on the peer device, TCP skbs will go through the NAPI callback. If there is no XDP program attached, the veth code does not perform any share check, and shared/cloned skbs could enter the GRO engine. Ignat reported a BUG triggered later-on due to the above condition: [ 53.970529][ C1] kernel BUG at net/core/skbuff.c:3574!

| CVE-2021-47013 | 1 Redhat | 3 Enterprise Linux, Rhel Eus, Rhev Hypervisor | 2024-08-04 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: net:emac/emac-mac: Fix a use after free in emac_mac_tx_buf_send In emac_mac_tx_buf_send, it calls emac_tx_fill_tpd(..,skb,..). If some error happens in emac_tx_fill_tpd(), the skb will be freed via dev_kfree_skb(skb) in error branch of emac_tx_fill_tpd(). But the freed skb is still used via skb->len by netdev_sent_queue(,skb->len). As i observed that emac_tx_fill_tpd() haven't modified the value of skb->len, thus my patch assigns skb->len to 'len' before the possible free and use 'len' instead of skb->len later. | ||||

| AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. | ||||
| CVE-2021-43975 | 5 Debian, Fedoraproject, Linux and 2 more | 21 Debian Linux, Fedora, Linux Kernel and 18 more | 2024-08-04 | 6.7 Medium |
| In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a crafted device) to trigger an out-of-bounds write via a crafted length value. | ||||
| CVE-2021-43527 | 5 Mozilla, Netapp, Oracle and 2 more | 17 Nss, Nss Esr, Cloud Backup and 14 more | 2024-08-04 | 9.8 Critical |
| NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1. | ||||
| CVE-2021-43267 | 4 Fedoraproject, Linux, Netapp and 1 more | 19 Fedora, Linux Kernel, H300e and 16 more | 2024-08-04 | 9.8 Critical |
| An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of user-supplied sizes for the MSG_CRYPTO message type. | ||||
| CVE-2021-38575 | 3 Insyde, Redhat, Tianocore | 5 Kernel, Enterprise Linux, Rhel Eus and 2 more | 2024-08-04 | 8.1 High |

| CVE-2021-34866 | 3 Linux, Netapp, Redhat | 19 Linux Kernel, H300e, H300e Firmware and 16 more | 2024-08-04 | 7.8 High |
| This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.14-rc3. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The issue results from the lack of proper validation of user-supplied eBPF programs, which can result in a type confusion condition. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-14689. | ||||
| CVE-2021-33909 | 7 Debian, Fedoraproject, Linux and 4 more | 16 Debian Linux, Fedora, Linux Kernel and 13 more | 2024-08-04 | 7.8 High |
| fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an unprivileged user, aka CID-8cae8cd89f05. | ||||
| CVE-2021-33910 | 5 Debian, Fedoraproject, Netapp and 2 more | 8 Debian Linux, Fedora, Hci Management Node and 5 more | 2024-08-04 | 5.5 Medium |
| basic/unit-name.c in systemd prior to 246.15, 247.8, 248.5, and 249.1 has a Memory Allocation with an Excessive Size Value (involving strdupa and alloca for a pathname controlled by a local attacker) that results in an operating system crash. | ||||
