SUSE CVE-2021-3975

A use-after-free flaw was found in libvirt. The qemuMonitorUnregister function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down...

SUSE CVE-2021-3996

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...

SUSE CVE-2021-3995

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 an unprivileged local attacker to unmount FUSE filesystems that belong to certain other users who have a UID that is a prefix of the UID of...

SUSE CVE-2021-4115

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...

SUSE CVE-2021-4145

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 mirrorwaitonconflicts without ensuring that it's not NULL. A malicious unprivileged user within the guest could use this flaw to crash the QEMU process on t...

SUSE CVE-2021-20265

A flaw was found in the way memory resources were freed in the unixstreamrecvmsg function in the Linux kernel when a signal was pending. This flaw allows an unprivileged local user to crash the system by exhausting available memory. The highest threat from this vulnerability is to system...

SUSE CVE-2021-23240

selinuxeditcopytfiles in sudoedit in Sudo before 1.9.5 allows a local unprivileged user to gain file ownership and escalate privileges by replacing a temporary file with a symlink to an arbitrary file target. This affects SELinux RBAC support in permissive mode. Machines without SELinux are not...

SUSE CVE-2021-27364

An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsitransportiscsi.c is adversely affected by the ability of an unprivileged user to craft Netlink messages...

SUSE CVE-2021-27365

An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have appropriate length constraints or checks, and can exceed the PAGESIZE value. An unprivileged user can send a Netlink message that is associated with iSCSI, and has a length up to the maximum leng...

SUSE CVE-2021-28700

xen/arm: No memory limit for dom0less domUs The dom0less feature allows an administrator to create multiple unprivileged domains directly from Xen. Unfortunately, the memory limit from them is not set. This allow a domain to allocate memory beyond what an administrator originally configured...

SUSE CVE-2021-33624

In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted e.g., because of type confusion and consequently an unprivileged BPF program can read arbitrary memory locations via a side-channel attack, aka CID-9183671af6db...

SUSE CVE-2021-34556

In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack...

SUSE CVE-2021-35477

In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled...

SUSE CVE-2021-38300

arch/mips/net/bpfjit.c in the Linux kernel before 5.4.10 can generate undesirable machine code when transforming unprivileged cBPF programs, allowing execution of arbitrary code within the kernel context. This occurs because conditional branches can exceed the 128 KB limit of the MIPS architectur...

SUSE CVE-2021-38492

When delegating navigations to the operating system, Firefox would accept the mk scheme which might allow attackers to launch pages and execute scripts in Internet Explorer in unprivileged mode. This bug only affects Firefox for Windows. Other operating systems are unaffected.. This vulnerability...

SUSE CVE-2021-41091

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 traver...

SUSE CVE-2021-41103

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...

SUSE CVE-2021-41864

preallocelemsandfreelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write...

SUSE CVE-2021-42097

GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A csrftoken value is not specific to a single user account. An attacker can obtain a value within the context of an unprivileged user account, and then use that value in a CSRF attack against an admin e.g., for account takeover...

SUSE CVE-2021-42257
