| CVE-2021-4145 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-11-21 | 4.9 MEDIUM | 6.5 MEDIUM |
| A NULL pointer dereference issue was found in the block mirror layer of QEMU in versions prior to 6.2.0. The `self` pointer is dereferenced in mirror_wait_on_conflicts() without ensuring that it's not NULL. A malicious unprivileged user within the guest could use this flaw to crash the QEMU process on the host when writing data reaches the threshold of mirroring node. | |||||
| CVE-2021-4115 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| There is a flaw in polkit which can allow an unprivileged user to cause polkit to crash, due to process file descriptor exhaustion. The highest threat from this vulnerability is to availability. NOTE: Polkit process outage duration is tied to the failing process being reaped and a new one being spawned | |||||
| CVE-2021-4112 | 1 Redhat | 5 Ansible Automation Platform, Ansible Automation Platform Early Access, Ansible Automation Platform Text-only Advisories and 2 more | 2024-11-21 | N/A | 8.8 HIGH |
| A flaw was found in ansible-tower where the default installation is vulnerable to job isolation escape. This flaw allows an attacker to elevate the privilege from a low privileged user to an AWX user from outside the isolated environment. | |||||
| CVE-2021-4104 | 4 Apache, Fedoraproject, Oracle and 1 more | 46 Log4j, Fedora, Advanced Supply Chain Planning and 43 more | 2024-11-21 | 6.0 MEDIUM | 7.5 HIGH |
| JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. | |||||
| CVE-2021-4093 | 4 Canonical, Fedoraproject, Linux and 1 more | 4 Ubuntu Linux, Fedora, Linux Kernel and 1 more | 2024-11-21 | 7.2 HIGH | 8.8 HIGH |
| A flaw was found in the KVM's AMD code for supporting the Secure Encrypted Virtualization-Encrypted State (SEV-ES). A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via a malicious VMGEXIT for a string I/O instruction (for example, outs or ins) using the exit reason SVM_EXIT_IOIO. This issue results in a crash of the entire system or a potential guest-to-host escape scenario. | |||||
| CVE-2021-4048 | 5 Fedoraproject, Julialang, Lapack Project and 2 more | 8 Fedora, Julia, Lapack and 5 more | 2024-11-21 | 6.4 MEDIUM | 9.1 CRITICAL |
| An out-of-bounds read flaw was found in the CLARRV, DLARRV, SLARRV, and ZLARRV functions in lapack through version 3.10.0, as also used in OpenBLAS before version 0.3.18. Specially crafted inputs passed to these functions could cause an application using lapack to crash or possibly disclose portions of its memory. | |||||
| CVE-2021-4024 | 3 Fedoraproject, Podman Project, Redhat | 3 Fedora, Podman, Enterprise Linux | 2024-11-21 | 6.4 MEDIUM | 6.5 MEDIUM |
| A flaw was found in podman. The `podman machine` function (used to create and manage Podman virtual machine containing a Podman process) spawns a `gvproxy` process on the host system. The `gvproxy` API is accessible on port 7777 on all IP addresses on the host. If that port is open on the host's firewall, an attacker can potentially use the `gvproxy` API to forward ports on the host to ports in the VM, making private services on the VM accessible to the network. This issue could be also used to interrupt the host's services by forwarding all ports to the VM. | |||||
| CVE-2021-45417 | 5 Advanced Intrusion Detection Environment Project, Canonical, Debian and 2 more | 7 Advanced Intrusion Detection Environment, Ubuntu Linux, Debian Linux and 4 more | 2024-11-21 | 7.2 HIGH | 7.8 HIGH |
| 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-2021-45078 | 5 Debian, Fedoraproject, Gnu and 2 more | 5 Debian Linux, Fedora, Binutils and 2 more | 2024-11-21 | 6.8 MEDIUM | 7.8 HIGH |
| stab_xcoff_builtin_type in stabs.c in GNU Binutils through 2.37 allows attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact, as demonstrated by an out-of-bounds write. NOTE: this issue exists because of an incorrect fix for CVE-2018-12699. | |||||
| CVE-2021-44733 | 5 Debian, Fedoraproject, Linux and 2 more | 20 Debian Linux, Fedora, Linux Kernel and 17 more | 2024-11-21 | 4.4 MEDIUM | 7.0 HIGH |
| A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11. This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object. | |||||
| CVE-2021-43860 | 4 Debian, Fedoraproject, Flatpak and 1 more | 4 Debian Linux, Fedora, Flatpak and 1 more | 2024-11-21 | 6.8 MEDIUM | 8.2 HIGH |
| Flatpak is a Linux application sandboxing and distribution framework. Prior to versions 1.12.3 and 1.10.6, Flatpak doesn't properly validate that the permissions displayed to the user for an app at install time match the actual permissions granted to the app at runtime, in the case that there's a null byte in the metadata file of an app. Therefore apps can grant themselves permissions without the consent of the user. Flatpak shows permissions to the user during install by reading them from the "xa.metadata" key in the commit metadata. This cannot contain a null terminator, because it is an untrusted GVariant. Flatpak compares these permissions to the *actual* metadata, from the "metadata" file to ensure it wasn't lied to. However, the actual metadata contents are loaded in several places where they are read as simple C-style strings. That means that, if the metadata file includes a null terminator, only the content of the file from *before* the terminator gets compared to xa.metadata. Thus, any permissions that appear in the metadata file after a null terminator are applied at runtime but not shown to the user. So maliciously crafted apps can give themselves hidden permissions. Users who have Flatpaks installed from untrusted sources are at risk in case the Flatpak has a maliciously crafted metadata file, either initially or in an update. This issue is patched in versions 1.12.3 and 1.10.6. As a workaround, users can manually check the permissions of installed apps by checking the metadata file or the xa.metadata key on the commit metadata. | |||||

| An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. | |||||
| CVE-2021-41817 | 6 Debian, Fedoraproject, Opensuse and 3 more | 9 Debian Linux, Fedora, Factory and 6 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Date.parse in the date gem through 3.2.0 for Ruby allows ReDoS (regular expression Denial of Service) via a long string. The fixed versions are 3.2.1, 3.1.2, 3.0.2, and 2.0.1. | |||||
| CVE-2021-40153 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2024-11-21 | 5.8 MEDIUM | 8.1 HIGH |
| squashfs_opendir in unsquash-1.c in Squashfs-Tools 4.5 stores the filename in the directory entry; this is then used by unsquashfs to create the new file during the unsquash. The filename is not validated for traversal outside of the destination directory, and thus allows writing to locations outside of the destination. | |||||
| CVE-2021-3997 | 3 Fedoraproject, Redhat, Systemd Project | 3 Fedora, Enterprise Linux, Systemd | 2024-11-21 | N/A | 5.5 MEDIUM |
| A flaw was found in systemd. An uncontrolled recursion in systemd-tmpfiles may lead to a denial of service at boot time when too many nested directories are created in /tmp. | |||||
| CVE-2021-3975 | 5 Canonical, Debian, Fedoraproject and 2 more | 14 Ubuntu Linux, Debian Linux, Fedora and 11 more | 2024-11-21 | N/A | 6.5 MEDIUM |
| A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial of service attack by causing the libvirt daemon to crash. | |||||
| CVE-2021-3948 | 2 Konveyor, Redhat | 3 Mig-controller, Enterprise Linux, Migration Toolkit | 2024-11-21 | 6.5 MEDIUM | 6.3 MEDIUM |
| An incorrect default permissions vulnerability was found in the mig-controller. Due to an incorrect cluster namespaces handling an attacker may be able to migrate a malicious workload to the target cluster, impacting confidentiality, integrity, and availability of the services located on that cluster. | |||||
| CVE-2021-3941 | 4 Debian, Fedoraproject, Openexr and 1 more | 4 Debian Linux, Fedora, Openexr and 1 more | 2024-11-21 | 2.1 LOW | 6.5 MEDIUM |
| In ImfChromaticities.cpp routine RGBtoXYZ(), there are some division operations such as `float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;` and `chroma.green.y * (X + Z))) / d;` but the divisor is not checked for a 0 value. A specially crafted file could trigger a divide-by-zero condition which could affect the availability of programs linked with OpenEXR. | |||||
| CVE-2021-3930 | 3 Debian, Qemu, Redhat | 10 Debian Linux, Qemu, Codeready Linux Builder and 7 more | 2024-11-21 | 2.1 LOW | 6.5 MEDIUM |
| An off-by-one error was found in the SCSI device emulation in QEMU. It could occur while processing MODE SELECT commands in mode_sense_page() if the 'page' argument was set to MODE_PAGE_ALLS (0x3f). A malicious guest could use this flaw to potentially crash QEMU, resulting in a denial of service condition. | |||||
| CVE-2021-3864 | 3 Debian, Linux, Redhat | 3 Debian Linux, Linux Kernel, Enterprise Linux | 2024-11-21 | N/A | 7.0 HIGH |
| A flaw was found in the way the dumpable flag setting was handled when certain SUID binaries executed its descendants. The prerequisite is a SUID binary that sets real UID equal to effective UID, and real GID equal to effective GID. The descendant will then have a dumpable value set to 1. As a result, if the descendant process crashes and core_pattern is set to a relative value, its core dump is stored in the current directory with uid:gid permissions. An unprivileged local user with eligible root SUID binary could use this flaw to place core dumps into root-owned directories, potentially resulting in escalation of privileges. | |||||
