A deserialization flaw in jackson-databind was found allowing code execution when given maliocusly crafted input to readValue method of ObjectMapper.

Source: Red Hat

Remedy

Mitigation to this problem is to not trigger polymorphic desrialization globally by using: objectMapper.enableDefaultTyping() and rather use @JsonTypeInfo on the class property to explicitly define the type information.

A remote stack overflow in the TIPC networking module. With FORTIFYSOURCE's stricter memcpy() bounds checking, this can be exploited to cause remote DOS via kernel panic on systems using TIPC. Prior to these bounds checks, and with a canary leak (or no CONFIGSTACKPROTECTOR), this can be exploited for RCE.

Reference: https://www.openwall.com/lists/oss-security/2022/02/10/1

Source: Red Hat

Remedy

The TIPC module will NOT be automatically loaded. When required, administrative action is needed to explicitly load this module. Loading the module can be prevented with the following instructions: # echo "install tipc /bin/true" >> /etc/modprobe.d/disable-tipc.conf The system will need to be restarted if the tipc module is loaded. In most circumstances, the TIPC kernel module will be unable to be unloaded while any network interfaces are active and the protocol is in use. If the system requires this module to work correctly, this mitigation may not be suitable.

Remedy

Ensure the tipc module is not loaded; unlike many other network protocols in the Linux kernel, the tipc module cannot be auto-loaded by an unprivileged user.

Path Traversal
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

It was discovered that libvirtd before versions 4.10.1 and 5.4.1 would permit read-only clients to use the virDomainSaveImageGetXMLDesc() API, specifying an arbitrary path which would be accessed with the permissions of the libvirtd process. An attacker with access to the libvirtd socket could use this to probe the existence of arbitrary files, cause denial of service or cause libvirtd to execute arbitrary programs.

1 / 4

Remedy

The Unix permissions of libvirt's read-only socket can be made more restrictive than the default (0777) by editing `/etc/libvirt/libvirtd.conf`. The settings `unix_sock_group = libvirt` and `unix_sock_ro_perms = 0770` will restrict access to only members of `libvirt`, who already have management access to virtual machines.

Use After Free
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

A flaw in the Linux Kernel found. If unprivileged users can mount FUSE filesystems, then can trigger use after free (UAF) that reads of write() buffers, allowing theft of (partial) /etc/shadow hashes or any other data from filesystem.

FUSE allows the userspace filesystem to specify on FUSEOPEN whether the file should use the normal kernel pagecache for handling read()/write() or just send FUSEREAD/FUSEWRITE requests directly to the userspace filesystem (using the flag FOPENDIRECTIO in fuseopenout::openflags).

In FOPENDIRECTIO mode, fusefilewriteiter() calls fusedirectwriteiter(), which normally calls fusedirectio(), which then imports the write buffer with fusegetuserpages(), which uses iovitergetpages() to grab references to userspace pages instead of actually copying memory.

On the filesystem device side, these pages can then either be read to userspace (via fusedevread()), or splice()d over into a pipe using fusedevspliceread() as pipe buffers with &nostealpipebufops.

This is wrong because after fusedevdoread() unlocks the FUSE request, the userspace filesystem can mark the request as completed, causing write() to return. At that point, the write buffer may be reused for other purposes, and the userspace filesystem should no longer have access to it.
