| CVE-2021-3695 | 4 Fedoraproject, Gnu, Netapp and 1 more | 14 Fedora, Grub2, Ontap Select Deploy Administration Utility and 11 more | 2024-11-21 | 4.4 MEDIUM | 4.5 MEDIUM |
| A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12. | |||||
| CVE-2021-3677 | 3 Fedoraproject, Postgresql, Redhat | 7 Fedora, Postgresql, Enterprise Linux and 4 more | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting. | |||||

| CVE-2021-3656 | 3 Fedoraproject, Linux, Redhat | 26 Fedora, Linux Kernel, 3scale Api Management and 23 more | 2024-11-21 | 7.2 HIGH | 8.8 HIGH |
| A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. | |||||
| CVE-2021-3640 | 5 Canonical, Debian, Fedoraproject and 2 more | 20 Ubuntu Linux, Debian Linux, Fedora and 17 more | 2024-11-21 | 6.9 MEDIUM | 7.0 HIGH |
| A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system. | |||||
| CVE-2021-3638 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2024-11-21 | 2.1 LOW | 6.5 MEDIUM |
| An out-of-bounds memory access flaw was found in the ATI VGA device emulation of QEMU. This flaw occurs in the ati_2d_blt() routine while handling MMIO write operations when the guest provides invalid values for the destination display parameters. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service. | |||||
| CVE-2021-3635 | 3 Fedoraproject, Linux, Redhat | 3 Fedora, Linux Kernel, Enterprise Linux | 2024-11-21 | 4.9 MEDIUM | 4.4 MEDIUM |
| A flaw was found in the Linux kernel netfilter implementation in versions prior to 5.5-rc7. A user with root (CAP_SYS_ADMIN) access is able to panic the system when issuing netfilter netflow commands. | |||||
| CVE-2021-3634 | 6 Debian, Fedoraproject, Libssh and 3 more | 7 Debian Linux, Fedora, Libssh and 4 more | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| A flaw has been found in libssh in versions prior to 0.9.6. The SSH protocol keeps track of two shared secrets during the lifetime of the session. One of them is called secret_hash and the other session_id. Initially, both of them are the same, but after key re-exchange, previous session_id is kept and used as an input to new secret_hash. Historically, both of these buffers had shared length variable, which worked as long as these buffers were same. But the key re-exchange operation can also change the key exchange method, which can be based on hash of different size, eventually creating "secret_hash" of different size than the session_id has. This becomes an issue when the session_id memory is zeroed or when it is used again during second key re-exchange. | |||||
| CVE-2021-3630 | 3 Debian, Djvulibre Project, Fedoraproject | 3 Debian Linux, Djvulibre, Fedora | 2024-11-21 | 4.3 MEDIUM | 5.5 MEDIUM |
