CVE-2021-4145 2 Qemu, Redhat 2 Qemu, Enterprise Linux 2024-02-04 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-2021-43389 4 Debian, Linux, Oracle and 1 more 6 Debian Linux, Linux Kernel, Communications Cloud Native Core Binding Support Function and 3 more 2024-02-04 2.1 LOW 5.5 MEDIUM
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-2021-32672 6 Debian, Fedoraproject, Netapp and 3 more 8 Debian Linux, Fedora, Management Services For Element Software and 5 more 2024-02-04 4.0 MEDIUM 4.3 MEDIUM
Redis is an open source, in-memory database that persists on disk. When using the Redis Lua Debugger, users can send malformed requests that cause the debugger’s protocol parser to read data beyond the actual buffer. This issue affects all versions of Redis with Lua debugging support (3.2 or newer). The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14.
CVE-2021-3653 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2024-02-04 6.1 MEDIUM 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 "int_ctl" field, this issue could allow a malicious L1 to enable AVIC support (Advanced Virtual Interrupt Controller) 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. This flaw affects Linux kernel versions prior to 5.14-rc7.
CVE-2021-41819 6 Debian, Fedoraproject, Opensuse and 3 more 9 Debian Linux, Fedora, Factory and 6 more 2024-02-04 5.0 MEDIUM 7.5 HIGH

CVE-2021-3672 6 C-ares Project, Fedoraproject, Nodejs and 3 more 17 C-ares, Fedora, Node.js and 14 more 2024-02-04 6.8 MEDIUM 5.6 MEDIUM
A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS (Domain Name Servers) can lead to output of wrong hostnames which might potentially lead to Domain Hijacking. The highest threat from this vulnerability is to confidentiality and integrity as well as system availability.
CVE-2021-43860 4 Debian, Fedoraproject, Flatpak and 1 more 4 Debian Linux, Fedora, Flatpak and 1 more 2024-02-04 6.8 MEDIUM 8.6 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-2021-3802 3 Fedoraproject, Redhat, Udisks Project 3 Fedora, Enterprise Linux, Udisks 2024-02-04 6.3 MEDIUM 4.2 MEDIUM
