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-2021-45463 4 Fedoraproject, Gegl, Gimp and 1 more 4 Fedora, Gegl, Gimp and 1 more 2024-11-21 6.8 MEDIUM 7.8 HIGH
load_cache in GEGL before 0.4.34 allows shell expansion when a pathname in a constructed command line is not escaped or filtered. This is caused by use of the system library function for execution of the ImageMagick convert fallback in magick-load. NOTE: GEGL releases before 0.4.34 are used in GIMP releases before 2.10.30; however, this does not imply that GIMP builds enable the vulnerable feature.
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.
CVE-2021-43389 4 Debian, Linux, Oracle and 1 more 6 Debian Linux, Linux Kernel, Communications Cloud Native Core Binding Support Function and 3 more 2024-11-21 2.1 LOW 5.5 MEDIUM

CVE-2021-41819 6 Debian, Fedoraproject, Opensuse and 3 more 9 Debian Linux, Fedora, Factory and 6 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
CGI::Cookie.parse in Ruby through 2.6.8 mishandles security prefixes in cookie names. This also affects the CGI gem through 0.3.0 for Ruby.
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.
