CVE-2021-4207 3 Debian, Qemu, Redhat 4 Debian Linux, Qemu, Advanced Virtualization and 1 more 2024-08-03 8.2 High
A flaw was found in the QXL display device emulation in QEMU. A double fetch of guest controlled values `cursor->header.width` and `cursor->header.height` can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. A malicious privileged guest user could use this flaw to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process.
CVE-2021-4028 3 Linux, Redhat, Suse 9 Linux Kernel, Enterprise Linux, Rhel Aus and 6 more 2024-08-03 7.8 High
A flaw in the Linux kernel's implementation of RDMA communications manager listener code allowed an attacker with local access to setup a socket to listen on a high port allowing for a list element to be used after free. Given the ability to execute code, a local attacker could leverage this use-after-free to crash the system or possibly escalate privileges on the system.
CVE-2021-4159 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2024-08-03 4.4 Medium
A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel.
CVE-2021-4122 2 Cryptsetup Project, Redhat 2 Cryptsetup, Enterprise Linux 2024-08-03 4.3 Medium
It was found that a specially crafted LUKS header could trick cryptsetup into disabling encryption during the recovery of the device. An attacker with physical access to the medium, such as a flash disk, could use this flaw to force a user into permanently disabling the encryption layer of that medium.
CVE-2021-4129 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-08-03 9.8 Critical
Mozilla developers and community members Julian Hector, Randell Jesup, Gabriele Svelto, Tyson Smith, Christian Holler, and Masayuki Nakano reported memory safety bugs present in Firefox 94. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 95, Firefox ESR < 91.4.0, and Thunderbird < 91.4.0.
CVE-2021-4112 1 Redhat 5 Ansible Automation Platform, Ansible Automation Platform Early Access, Ansible Automation Platform Text-only Advisories and 2 more 2024-08-03 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-2021-4145 2 Qemu, Redhat 2 Qemu, Enterprise Linux 2024-08-03 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-2021-4156 3 Debian, Libsndfile Project, Redhat 3 Debian Linux, Libsndfile, Enterprise Linux 2024-08-03 7.1 High
An out-of-bounds read flaw was found in libsndfile's FLAC codec functionality. An attacker who is able to submit a specially crafted file (via tricking a user to open or otherwise) to an application linked with libsndfile and using the FLAC codec, could trigger an out-of-bounds read that would most likely cause a crash but could potentially leak memory information that could be used in further exploitation of other flaws.
CVE-2021-4140 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-08-03 10.0 Critical
It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox. This vulnerability affects Firefox ESR < 91.5, Firefox < 96, and Thunderbird < 91.5.
CVE-2021-4104 4 Apache, Fedoraproject, Oracle and 1 more 59 Log4j, Fedora, Advanced Supply Chain Planning and 56 more 2024-08-03 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-2021-4083 5 Debian, Linux, Netapp and 2 more 30 Debian Linux, Linux Kernel, H300e and 27 more 2024-08-03 7.0 High
A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system. This flaw affects Linux kernel versions prior to 5.16-rc4.
CVE-2021-4011 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-08-03 7.8 High

CVE-2021-4008 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-08-03 7.8 High
A flaw was found in xorg-x11-server in versions before 21.1.2 and before 1.20.14. An out-of-bounds access can occur in the SProcRenderCompositeGlyphs function. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-4048 5 Fedoraproject, Julialang, Lapack Project and 2 more 8 Fedora, Julia, Lapack and 5 more 2024-08-03 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-2021-4093 4 Canonical, Fedoraproject, Linux and 1 more 4 Ubuntu Linux, Fedora, Linux Kernel and 1 more 2024-08-03 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-2021-4091 2 Port389, Redhat 11 389-ds-base, Directory Server, Enterprise Linux and 8 more 2024-08-03 7.5 High
A double-free was found in the way 389-ds-base handles virtual attributes context in persistent searches. An attacker could send a series of search requests, forcing the server to behave unexpectedly, and crash.
CVE-2021-4024 3 Fedoraproject, Podman Project, Redhat 3 Fedora, Podman, Enterprise Linux 2024-08-03 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-2021-4009 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-08-03 7.8 High
A flaw was found in xorg-x11-server in versions before 21.1.2 and before 1.20.14. An out-of-bounds access can occur in the SProcXFixesCreatePointerBarrier function. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-3999 4 Debian, Gnu, Netapp and 1 more 16 Debian Linux, Glibc, E-series Performance Analyzer and 13 more 2024-08-03 7.8 High
A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and escalate their privileges on the system.
CVE-2021-4002 5 Debian, Fedoraproject, Linux and 2 more 7 Debian Linux, Fedora, Linux Kernel and 4 more 2024-08-03 4.4 Medium
A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the memory pages. A local user could use this flaw to get unauthorized access to some data.
