CVE-2021-33620 3 Debian, Fedoraproject, Squid-cache 3 Debian Linux, Fedora, Squid 2022-06-03 4.0 MEDIUM 6.5 MEDIUM
Squid before 4.15 and 5.x before 5.0.6 allows remote servers to cause a denial of service (affecting availability to all clients) via an HTTP response. The issue trigger is a header that can be expected to exist in HTTP traffic without any malicious intent by the server.
CVE-2021-3658 2 Bluez, Fedoraproject 2 Bluez, Fedora 2022-06-03 3.3 LOW 6.5 MEDIUM
bluetoothd from bluez incorrectly saves adapters' Discoverable status when a device is powered down, and restores it when powered up. If a device is powered down while discoverable, it will be discoverable when powered on again. This could lead to inadvertent exposure of the bluetooth stack to physically nearby attackers.
CVE-2021-25636 2 Fedoraproject, Libreoffice 2 Fedora, Libreoffice 2022-06-03 5.0 MEDIUM 7.5 HIGH
LibreOffice supports digital signatures of ODF documents and macros within documents, presenting visual aids that no alteration of the document occurred since the last signing and that the signature is valid. An Improper Certificate Validation vulnerability in LibreOffice allowed an attacker to create a digitally signed ODF document, by manipulating the documentsignatures.xml or macrosignatures.xml stream within the document to contain both "X509Data" and "KeyValue" children of the "KeyInfo" tag, which when opened caused LibreOffice to verify using the "KeyValue" but to report verification with the unrelated "X509Data" value. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.5.
CVE-2010-4176 3 Dracut Project, Fedoraproject, Udev Project 3 Dracut, Fedora, Udev 2022-06-03 4.0 MEDIUM N/A
plymouth-pretrigger.sh in dracut and udev, when running on Fedora 13 and 14, sets weak permissions for the /dev/systty device file, which allows remote authenticated users to read terminal data from tty0 for local users.
CVE-2021-3543 3 Fedoraproject, Nitro Enclaves Project, Redhat 3 Fedora, Nitro Enclaves, Enterprise Linux 2022-06-03 7.2 HIGH 6.7 MEDIUM
A flaw null pointer dereference in the Nitro Enclaves kernel driver was found in the way that Enclaves VMs forces closures on the enclave file descriptor. A local user of a host machine could use this flaw to crash the system or escalate their privileges on the system.
CVE-2021-26314 6 Amd, Arm, Broadcom and 3 more 11 Ryzen 5 5600x, Ryzen 7 2700x, Ryzen Threadripper 2990wx and 8 more 2022-06-03 2.1 LOW 5.5 MEDIUM
Potential floating point value injection in all supported CPU products, in conjunction with software vulnerabilities relating to speculative execution with incorrect floating point results, may cause the use of incorrect data from FPVI and may result in data leakage.
CVE-2021-28972 3 Fedoraproject, Linux, Netapp 5 Fedora, Linux Kernel, Cloud Backup and 2 more 2022-06-03 7.2 HIGH 6.7 MEDIUM
In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux kernel through 5.11.8, the RPA PCI Hotplug driver has a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing userspace to write data to the kernel stack frame directly. This occurs because add_slot_store and remove_slot_store mishandle drc_name '\0' termination, aka CID-cc7a0bb058b8.
CVE-2021-21334 2 Fedoraproject, Linuxfoundation 2 Fedora, Containerd 2022-06-03 4.3 MEDIUM 6.3 MEDIUM
In containerd (an industry-standard container runtime) before versions 1.3.10 and 1.4.4, containers launched through containerd's CRI implementation (through Kubernetes, crictl, or any other pod/container client that uses the containerd CRI service) that share the same image may receive incorrect environment variables, including values that are defined for other containers. If the affected containers have different security contexts, this may allow sensitive information to be unintentionally shared. If you are not using containerd's CRI implementation (through one of the mechanisms described above), you are not vulnerable to this issue. If you are not launching multiple containers or Kubernetes pods from the same image which have different environment variables, you are not vulnerable to this issue. If you are not launching multiple containers or Kubernetes pods from the same image in rapid succession, you have reduced likelihood of being vulnerable to this issue This vulnerability has been fixed in containerd 1.3.10 and containerd 1.4.4. Users should update to these versions.
CVE-2021-3739 3 Fedoraproject, Linux, Netapp 18 Fedora, Linux Kernel, Baseboard Management Controller H300e and 15 more 2022-06-01 3.6 LOW 7.1 HIGH
A NULL pointer dereference flaw was found in the btrfs_rm_device function in fs/btrfs/volumes.c in the Linux Kernel, where triggering the bug requires ‘CAP_SYS_ADMIN’. This flaw allows a local attacker to crash the system or leak kernel internal information. The highest threat from this vulnerability is to system availability.
CVE-2021-44733 5 Debian, Fedoraproject, Linux and 2 more 20 Debian Linux, Fedora, Linux Kernel and 17 more 2022-06-01 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-2020-4031 4 Canonical, Fedoraproject, Freerdp and 1 more 4 Ubuntu Linux, Fedora, Freerdp and 1 more 2022-06-01 4.3 MEDIUM 7.5 HIGH
In FreeRDP before version 2.1.2, there is a use-after-free in gdi_SelectObject. All FreeRDP clients using compatibility mode with /relax-order-checks are affected. This is fixed in version 2.1.2.
CVE-2020-4032 4 Canonical, Fedoraproject, Freerdp and 1 more 4 Ubuntu Linux, Fedora, Freerdp and 1 more 2022-06-01 4.3 MEDIUM 4.3 MEDIUM
In FreeRDP before version 2.1.2, there is an integer casting vulnerability in update_recv_secondary_order. All clients with +glyph-cache /relax-order-checks are affected. This is fixed in version 2.1.2.
CVE-2020-4033 4 Canonical, Fedoraproject, Freerdp and 1 more 4 Ubuntu Linux, Fedora, Freerdp and 1 more 2022-06-01 6.4 MEDIUM 6.5 MEDIUM
In FreeRDP before version 2.1.2, there is an out of bounds read in RLEDECOMPRESS. All FreeRDP based clients with sessions with color depth < 32 are affected. This is fixed in version 2.1.2.
CVE-2021-30159 3 Debian, Fedoraproject, Mediawiki 3 Debian Linux, Fedora, Mediawiki 2022-05-27 4.0 MEDIUM 4.3 MEDIUM
An issue was discovered in MediaWiki before 1.31.12 and 1.32.x through 1.35.x before 1.35.2. Users can bypass intended restrictions on deleting pages in certain "fast double move" situations. MovePage::isValidMoveTarget() uses FOR UPDATE, but it's only called if Title::getArticleID() returns non-zero with no special flags. Next, MovePage::moveToInternal() will delete the page if getArticleID(READ_LATEST) is non-zero. Therefore, if the page is missing in the replica DB, isValidMove() will return true, and then moveToInternal() will unconditionally delete the page if it can be found in the master.
CVE-2021-22174 3 Fedoraproject, Oracle, Wireshark 3 Fedora, Zfs Storage Appliance, Wireshark 2022-05-27 5.0 MEDIUM 7.5 HIGH
Crash in USB HID dissector in Wireshark 3.4.0 to 3.4.2 allows denial of service via packet injection or crafted capture file
CVE-2021-22173 3 Fedoraproject, Oracle, Wireshark 3 Fedora, Zfs Storage Appliance, Wireshark 2022-05-27 5.0 MEDIUM 7.5 HIGH
Memory leak in USB HID dissector in Wireshark 3.4.0 to 3.4.2 allows denial of service via packet injection or crafted capture file
CVE-2021-26933 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2022-05-27 2.1 LOW 5.5 MEDIUM
An issue was discovered in Xen 4.9 through 4.14.x. On Arm, a guest is allowed to control whether memory accesses are bypassing the cache. This means that Xen needs to ensure that all writes (such as the ones during scrubbing) have reached the memory before handing over the page to a guest. Unfortunately, the operation to clean the cache is happening before checking if the page was scrubbed. Therefore there is no guarantee when all the writes will reach the memory.
CVE-2021-29623 2 Exiv2, Fedoraproject 2 Exiv2, Fedora 2022-05-27 4.3 MEDIUM 3.3 LOW
Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. A read of uninitialized memory was found in Exiv2 versions v0.27.3 and earlier. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The read of uninitialized memory is triggered when Exiv2 is used to read the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to leak a few bytes of stack memory, if they can trick the victim into running Exiv2 on a crafted image file. The bug is fixed in version v0.27.4.
CVE-2021-0089 3 Debian, Fedoraproject, Intel 12 Debian Linux, Fedora, Celeron Processors and 9 more 2022-05-24 2.1 LOW 6.5 MEDIUM
Observable response discrepancy in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.
CVE-2020-8156 2 Fedoraproject, Nextcloud 2 Fedora, Nextcloud Mail 2022-05-24 6.8 MEDIUM 7.0 HIGH
A missing verification of the TLS host in Nextcloud Mail 1.1.3 allowed a man in the middle attack.
