Multiple vulnerabilities in the samba filesystem (smbfs) in Linux kernel 2.4 and 2.6 allow remote samba servers to cause a denial of service (crash) or gain sensitive information from kernel memory via a samba server (1) returning more data than requested to the smb_proc_read function, (2) returning a data offset from outside the samba packet to the smb_proc_readX function, (3) sending a certain TRANS2 fragmented packet to the smb_receive_trans2 function, (4) sending a samba packet with a certain header size to the smb_proc_readX_data function, or (5) sending a certain packet based offset for the data in a packet to the smb_receive_trans2 function.

The smb_recv_trans2 function call in the samba filesystem (smbfs) in Linux kernel 2.4 and 2.6 does not properly handle the re-assembly of fragmented packets correctly, which could allow remote samba servers to (1) read arbitrary kernel information or (2) raise a counter value to an arbitrary number by sending the first part of the fragmented packet multiple times.

The containers/image library used by the container tools Podman, Buildah, and Skopeo in Red Hat Enterprise Linux version 8 and CRI-O in OpenShift Container Platform, does not enforce TLS connections to the container registry authorization service. An attacker could use this vulnerability to launch a MiTM attack and steal login credentials or bearer tokens.

GRUB2 contained integer overflows when handling the initrd command, leading to a heap-based buffer overflow.

Unspecified vulnerability in the Interstage Management Console, as used in Fujitsu Interstage Application Server 6.0 through 9.0.0A, Apworks Modelers-J 6.0 through 7.0, and Studio 8.0.1 and 9.0.0, allows remote attackers to read or delete arbitrary files via unspecified vectors.

GRUB2: avoid loading unsigned kernels when GRUB is booted directly under secureboot without shim

Opensc: multiple memory issues with pkcs15-init (enrollment tool)

GRUB2 contains a race condition leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing.

The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in drivers/net/ethernet/qualcomm/emac/emac.c if a physically proximate attacker unplugs an emac based device.

A race condition vulnerability was found in rpm. A local unprivileged user could use this flaw to bypass the checks that were introduced in response to CVE-2017-7500 and CVE-2017-7501, potentially gaining root privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A use-after-free vulnerability was found in usbredir in versions prior to 0.11.0 in the usbredirparser_serialize() in usbredirparser/usbredirparser.c. This issue occurs when serializing large amounts of buffered write data in the case of a slow or blocked destination.

A race condition was found in the Linux kernels implementation of the floppy disk drive controller driver software. The impact of this issue is lessened by the fact that the default permissions on the floppy device (/dev/fd0) are restricted to root. If the permissions on the device have changed the impact changes greatly. In the default configuration root (or equivalent) permissions are required to attack this flaw.

Sssd: use-after-free crash in sssd' 'sssd_pam' process

The default OCI linux spec in oci/defaults{_linux}.go in Docker/Moby from 1.11 to current does not block /proc/acpi pathnames. The flaw allows an attacker to modify host's hardware like enabling/disabling bluetooth or turning up/down keyboard brightness.

Ansible: malicious role archive can cause ansible-galaxy to overwrite arbitrary files

A vulnerability found in udisks2. This flaw allows an attacker to input a specially crafted image file/USB leading to kernel panic. The highest threat from this vulnerability is to system availability.

Platform: token exposed at importing project

A flaw was found in libvirt while it generates SELinux MCS category pairs for VMs' dynamic labels. This flaw allows one exploited guest to access files labeled for another guest, resulting in the breaking out of sVirt confinement. The highest threat from this vulnerability is to confidentiality and integrity.

OpenFabrics ibutils 1.5.7 allows local users to overwrite arbitrary files via a symlink attack on (1) ibdiagnet.db, (2) ibdiagnet.fdbs, (3) ibdiagnet_ibis.log, (4) ibdiagnet.log, (5) ibdiagnet.lst, (6) ibdiagnet.mcfdbs, (7) ibdiagnet.pkey, (8) ibdiagnet.psl, (9) ibdiagnet.slvl, or (10) ibdiagnet.sm in /tmp/.

Libssh: improper sanitation of paths received from scp servers

An out-of-bounds read flaw was found in the Linux kernel’s TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory.

There is an open race window when writing output in the following utilities in GNU binutils version 2.35 and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users), an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink.

A use-after-free vulnerability was found in drm_lease_held in drivers/gpu/drm/drm_lease.c in the Linux kernel due to a race problem. This flaw allows a local user privilege attacker to cause a denial of service (DoS) or a kernel information leak.

libuser 0.56 and 0.57 has a TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees.

Sblim-cmpi-base: insecure temporary file creation in sblim-cmpi-base provider registration scripts allows local symlink attack

Gfs2-utils: gfs2-utils: heap out-of-bounds read via unchecked ea_num_ptrs in extended attribute processing

Sblim-sfcb: sblim-sfcb: privileged file corruption and denial of service via insecure temporary file handling

Race condition in the (1) load_elf_library and (2) binfmt_aout function calls for uselib in Linux kernel 2.4 through 2.429-rc2 and 2.6 through 2.6.10 allows local users to execute arbitrary code by manipulating the VMA descriptor.

Buffer overflow in the VFAT filesystem implementation in the Linux kernel before 3.3 allows local users to gain privileges or cause a denial of service (system crash) via a VFAT write operation on a filesystem with the utf8 mount option, which is not properly handled during UTF-8 to UTF-16 conversion.

The init.d script for the X.Org X11 xfs font server on various Linux distributions might allow local users to change the permissions of arbitrary files via a symlink attack on the /tmp/.font-unix temporary file.

The KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges or cause a denial of service (system crash) via a VAPIC synchronization operation involving a page-end address.

Shim: out-of-bounds read printing error messages

A flaw was found in pacemaker up to and including version 2.0.1. An insufficient verification inflicted preference of uncontrolled processes can lead to DoS

Imagemagick: heap use-after-free in coders/bmp.c

A certain Red Hat build of the pam_ssh_agent_auth module on Red Hat Enterprise Linux (RHEL) 6 and Fedora Rawhide calls the glibc error function instead of the error function in the OpenSSH codebase, which allows local users to obtain sensitive information from process memory or possibly gain privileges via crafted use of an application that relies on this module, as demonstrated by su and sudo.
