CVE-2021-41159 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2024-11-21 6.8 MEDIUM 5.8 MEDIUM
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. All FreeRDP clients prior to version 2.4.1 using gateway connections (`/gt:rpc`) fail to validate input data. A malicious gateway might allow client memory to be written out of bounds. This issue has been resolved in version 2.4.1. If you are unable to update then use `/gt:http` rather than /gt:rdp connections if possible or use a direct connection without a gateway.
CVE-2021-41133 3 Debian, Fedoraproject, Flatpak 3 Debian Linux, Fedora, Flatpak 2024-11-21 4.6 MEDIUM 8.8 HIGH
Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. In versions prior to 1.10.4 and 1.12.0, Flatpak apps with direct access to AF_UNIX sockets such as those used by Wayland, Pipewire or pipewire-pulse can trick portals and other host-OS services into treating the Flatpak app as though it was an ordinary, non-sandboxed host-OS process. They can do this by manipulating the VFS using recent mount-related syscalls that are not blocked by Flatpak's denylist seccomp filter, in order to substitute a crafted `/.flatpak-info` or make that file disappear entirely. Flatpak apps that act as clients for AF_UNIX sockets such as those used by Wayland, Pipewire or pipewire-pulse can escalate the privileges that the corresponding services will believe the Flatpak app has. Note that protocols that operate entirely over the D-Bus session bus (user bus), system bus or accessibility bus are not affected by this. This is due to the use of a proxy process `xdg-dbus-proxy`, whose VFS cannot be manipulated by the Flatpak app, when interacting with these buses. Patches exist for versions 1.10.4 and 1.12.0, and as of time of publication, a patch for version 1.8.2 is being planned. There are no workarounds aside from upgrading to a patched version.
CVE-2021-41103 3 Debian, Fedoraproject, Linuxfoundation 3 Debian Linux, Fedora, Containerd 2024-11-21 7.2 HIGH 7.8 HIGH
containerd is an open source container runtime with an emphasis on simplicity, robustness and portability. A bug was found in containerd where container root directories and some plugins had insufficiently restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and execute programs. When containers included executable programs with extended permission bits (such as setuid), unprivileged Linux users could discover and execute those programs. When the UID of an unprivileged Linux user on the host collided with the file owner or group inside a container, the unprivileged Linux user on the host could discover, read, and modify those files. This vulnerability has been fixed in containerd 1.4.11 and containerd 1.5.7. Users should update to these version when they are released and may restart containers or update directory permissions to mitigate the vulnerability. Users unable to update should limit access to the host to trusted users. Update directory permission on container bundles directories.
CVE-2021-41099 5 Debian, Fedoraproject, Netapp and 2 more 5 Debian Linux, Fedora, Management Services For Element Software And Netapp Hci and 2 more 2024-11-21 6.0 MEDIUM 7.5 HIGH
Redis is an open source, in-memory database that persists on disk. An integer overflow bug in the underlying string library can be used to corrupt the heap and potentially result with denial of service or remote code execution. The vulnerability involves changing the default proto-max-bulk-len configuration parameter to a very large value and constructing specially crafted network payloads or commands. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the proto-max-bulk-len configuration parameter. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command.
CVE-2021-41092 2 Docker, Fedoraproject 2 Command Line Interface, Fedora 2024-11-21 5.0 MEDIUM 5.4 MEDIUM
Docker CLI is the command line interface for the docker container runtime. A bug was found in the Docker CLI where running `docker login my-private-registry.example.com` with a misconfigured configuration file (typically `~/.docker/config.json`) listing a `credsStore` or `credHelpers` that could not be executed would result in any provided credentials being sent to `registry-1.docker.io` rather than the intended private registry. This bug has been fixed in Docker CLI 20.10.9. Users should update to this version as soon as possible. For users unable to update ensure that any configured credsStore or credHelpers entries in the configuration file reference an installed credential helper that is executable and on the PATH.
CVE-2021-41091 2 Fedoraproject, Mobyproject 2 Fedora, Moby 2024-11-21 4.6 MEDIUM 6.3 MEDIUM
Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where the data directory (typically `/var/lib/docker`) contained subdirectories with insufficiently restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and execute programs. When containers included executable programs with extended permission bits (such as `setuid`), unprivileged Linux users could discover and execute those programs. When the UID of an unprivileged Linux user on the host collided with the file owner or group inside a container, the unprivileged Linux user on the host could discover, read, and modify those files. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade limit access to the host to trusted users. Limit access to host volumes to trusted containers.
CVE-2021-41089 2 Fedoraproject, Mobyproject 2 Fedora, Moby 2024-11-21 4.4 MEDIUM 2.8 LOW
Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where attempting to copy files using `docker cp` into a specially-crafted container can result in Unix file permission changes for existing files in the host’s filesystem, widening access to others. This bug does not directly allow files to be read, modified, or executed without an additional cooperating process. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers do not need to be restarted.
CVE-2021-41073 4 Debian, Fedoraproject, Linux and 1 more 21 Debian Linux, Fedora, Linux Kernel and 18 more 2024-11-21 7.2 HIGH 7.8 HIGH
loop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by using /proc/<pid>/maps for exploitation.
CVE-2021-40839 2 Fedoraproject, Rencode Project 2 Fedora, Rencode 2024-11-21 5.0 MEDIUM 7.5 HIGH

CVE-2021-40530 2 Cryptopp, Fedoraproject 2 Crypto\+\+, Fedora 2024-11-21 2.6 LOW 5.9 MEDIUM
The ElGamal implementation in Crypto++ through 8.5 allows plaintext recovery because, during interaction between two cryptographic libraries, a certain dangerous combination of the prime defined by the receiver's public key, the generator defined by the receiver's public key, and the sender's ephemeral exponents can lead to a cross-configuration attack against OpenPGP.
CVE-2021-40529 3 Botan Project, Fedoraproject, Mozilla 3 Botan, Fedora, Thunderbird 2024-11-21 2.6 LOW 5.9 MEDIUM
The ElGamal implementation in Botan through 2.18.1, as used in Thunderbird and other products, allows plaintext recovery because, during interaction between two cryptographic libraries, a certain dangerous combination of the prime defined by the receiver's public key, the generator defined by the receiver's public key, and the sender's ephemeral exponents can lead to a cross-configuration attack against OpenPGP.
CVE-2021-40490 4 Debian, Fedoraproject, Linux and 1 more 29 Debian Linux, Fedora, Linux Kernel and 26 more 2024-11-21 4.4 MEDIUM 7.0 HIGH
A race condition was discovered in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in the Linux kernel through 5.13.13.
CVE-2021-40438 9 Apache, Broadcom, Debian and 6 more 18 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 15 more 2024-11-21 6.8 MEDIUM 9.0 CRITICAL
A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.
CVE-2021-40403 3 Debian, Fedoraproject, Gerbv Project 3 Debian Linux, Fedora, Gerbv 2024-11-21 4.3 MEDIUM 6.3 MEDIUM
An information disclosure vulnerability exists in the pick-and-place rotation parsing functionality of Gerbv 2.7.0 and dev (commit b5f1eacd), and Gerbv forked 2.8.0. A specially-crafted pick-and-place file can exploit the missing initialization of a structure to leak memory contents. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2021-40401 3 Debian, Fedoraproject, Gerbv Project 3 Debian Linux, Fedora, Gerbv 2024-11-21 6.8 MEDIUM 8.6 HIGH
A use-after-free vulnerability exists in the RS-274X aperture definition tokenization functionality of Gerbv 2.7.0 and dev (commit b5f1eacd) and Gerbv forked 2.7.1. A specially-crafted gerber file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2021-40391 3 Debian, Fedoraproject, Gerbv Project 3 Debian Linux, Fedora, Gerbv 2024-11-21 7.5 HIGH 9.8 CRITICAL
An out-of-bounds write vulnerability exists in the drill format T-code tool number functionality of Gerbv 2.7.0, dev (commit b5f1eacd), and the forked version of Gerbv (commit 71493260). A specially-crafted drill file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2021-40346 3 Debian, Fedoraproject, Haproxy 3 Debian Linux, Fedora, Haproxy 2024-11-21 5.0 MEDIUM 7.5 HIGH
An integer overflow exists in HAProxy 2.0 through 2.5 in htx_add_header that can be exploited to perform an HTTP request smuggling attack, allowing an attacker to bypass all configured http-request HAProxy ACLs and possibly other ACLs.
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.
CVE-2021-3997 3 Fedoraproject, Redhat, Systemd Project 3 Fedora, Enterprise Linux, Systemd 2024-11-21 N/A 5.5 MEDIUM
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-2021-3996 2 Fedoraproject, Kernel 2 Fedora, Util-linux 2024-11-21 N/A 5.5 MEDIUM
A logic error was found in the libmount library of util-linux in the function that allows an unprivileged user to unmount a FUSE filesystem. This flaw allows a local user on a vulnerable system to unmount other users' filesystems that are either world-writable themselves (like /tmp) or mounted in a world-writable directory. An attacker may use this flaw to cause a denial of service to applications that use the affected filesystems.
