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-2021-3979 2 Fedoraproject, Redhat 8 Fedora, Ceph Storage, Ceph Storage For Ibm Z Systems and 5 more 2024-11-21 N/A 6.5 MEDIUM
A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.
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-2021-3935 4 Debian, Fedoraproject, Pgbouncer and 1 more 4 Debian Linux, Fedora, Pgbouncer and 1 more 2024-11-21 5.1 MEDIUM 8.1 HIGH
When PgBouncer is configured to use "cert" authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of TLS certificate verification and encryption. This flaw affects PgBouncer versions prior to 1.16.1.
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.
CVE-2021-3839 3 Dpdk, Fedoraproject, Redhat 4 Data Plane Development Kit, Fedora, Enterprise Linux and 1 more 2024-11-21 N/A 7.5 HIGH
A flaw was found in the vhost library in DPDK. Function vhost_user_set_inflight_fd() does not validate `msg->payload.inflight.num_queues`, possibly causing out-of-bounds memory read/write. Any software using DPDK vhost library may crash as a result of this vulnerability.
CVE-2021-3827 1 Redhat 4 Enterprise Linux, Keycloak, Openshift Container Platform and 1 more 2024-11-21 N/A 6.8 MEDIUM
A flaw was found in keycloak, where the default ECP binding flow allows other authentication flows to be bypassed. By exploiting this behavior, an attacker can bypass the MFA authentication by sending a SOAP request with an AuthnRequest and Authorization header with the user's credentials. The highest threat from this vulnerability is to confidentiality and integrity.
CVE-2021-3802 3 Fedoraproject, Redhat, Udisks Project 3 Fedora, Enterprise Linux, Udisks 2024-11-21 6.3 MEDIUM 4.2 MEDIUM
A vulnerability found in udisks2. This flaw allows an attacker to input a specially crafted image file/USB leading to kernel panic. The highest threat from this vulnerability is to system availability.
CVE-2021-3772 5 Debian, Linux, Netapp and 2 more 26 Debian Linux, Linux Kernel, E-series Santricity Os Controller and 23 more 2024-11-21 5.8 MEDIUM 6.5 MEDIUM
A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and the attacker can send packets with spoofed IP addresses.
CVE-2021-3753 3 Linux, Netapp, Redhat 18 Linux Kernel, Active Iq Unified Manager, Bootstrap Os and 15 more 2024-11-21 1.9 LOW 4.7 MEDIUM
A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl (KDSETMDE). The highest threat from this vulnerability is to data confidentiality.
CVE-2021-3752 6 Debian, Fedoraproject, Linux and 3 more 27 Debian Linux, Fedora, Linux Kernel and 24 more 2024-11-21 7.9 HIGH 7.1 HIGH
A use-after-free flaw was found in the Linux kernel’s Bluetooth subsystem in the way user calls connect to the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the system or escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-3750 2 Qemu, Redhat 2 Qemu, Enterprise Linux 2024-11-21 4.6 MEDIUM 8.2 HIGH
A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be written to the controller's registers and trigger undesirable actions (such as reset) while the device is still transferring packets. This can ultimately lead to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code within the context of the QEMU process on the host. This flaw affects QEMU versions before 7.0.0.
CVE-2021-3748 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2024-11-21 6.9 MEDIUM 7.5 HIGH
A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a denial of service condition, or potentially execute code on the host with the privileges of the QEMU process.
CVE-2021-3746 3 Fedoraproject, Libtpms Project, Redhat 3 Fedora, Libtpms, Enterprise Linux 2024-11-21 7.1 HIGH 6.5 MEDIUM
A flaw was found in the libtpms code that may cause access beyond the boundary of internal buffers. The vulnerability is triggered by specially-crafted TPM2 command packets that then trigger the issue when the state of the TPM2's volatile state is written. The highest threat from this vulnerability is to system availability. This issue affects libtpms versions before 0.8.5, before 0.7.9 and before 0.6.6.
CVE-2021-3744 5 Debian, Fedoraproject, Linux and 2 more 24 Debian Linux, Fedora, Linux Kernel and 21 more 2024-11-21 2.1 LOW 5.5 MEDIUM
A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808.
CVE-2021-3737 6 Canonical, Fedoraproject, Netapp and 3 more 17 Ubuntu Linux, Fedora, Hci and 14 more 2024-11-21 7.1 HIGH 7.5 HIGH
A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability.
CVE-2021-3733 4 Fedoraproject, Netapp, Python and 1 more 20 Extra Packages For Enterprise Linux, Fedora, Hci Compute Node Firmware and 17 more 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability.
