Ubuntu Security Notice USN-6537-1
December 06, 2023
linux-gcp vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 23.10
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
Details:
Yu Hao discovered that the UBI driver in the Linux kernel did not properly
check for MTD with zero erasesize during device attachment. A local
privileged attacker could use this to cause a denial of service (system
crash). (CVE-2023-31085)
Lucas Leong discovered that the netfilter subsystem in the Linux kernel did
not properly validate some attributes passed from userspace. A local
attacker could use this to cause a denial of service (system crash) or
possibly expose sensitive information (kernel memory). (CVE-2023-39189)
Bien Pham discovered that the netfiler subsystem in the Linux kernel
contained a race condition, leading to a use-after-free vulnerability. A
local user could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2023-4244)
Kyle Zeng discovered that the IPv4 implementation in the Linux kernel did
not properly handle socket buffers (skb) when performing IP routing in
certain circumstances, leading to a null pointer dereference vulnerability.
A privileged attacker could use this to cause a denial of service (system
crash). (CVE-2023-42754)
Yikebaer Aizezi discovered that the ext4 file system implementation in the
Linux kernel contained a use-after-free vulnerability when handling inode
extent metadata. An attacker could use this to construct a malicious ext4
file system image that, when mounted, could cause a denial of service
(system crash). (CVE-2023-45898)
Maxim Levitsky discovered that the KVM nested virtualization (SVM)
implementation for AMD processors in the Linux kernel did not properly
handle x2AVIC MSRs. An attacker in a guest VM could use this to cause a
denial of service (host kernel crash). (CVE-2023-5090)
Jason Wang discovered that the virtio ring implementation in the Linux
kernel did not properly handle iov buffers in some situations. A local
attacker in a guest VM could use this to cause a denial of service (host
system crash). (CVE-2023-5158)
Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel
did not properly handle queue initialization failures in certain
situations, leading to a use-after-free vulnerability. A remote attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2023-5178)
It was discovered that the SMB network file sharing protocol implementation
in the Linux kernel did not properly handle certain error conditions,
leading to a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2023-5345)
Murray McAllister discovered that the VMware Virtual GPU DRM driver in the
Linux kernel did not properly handle memory objects when storing surfaces,
leading to a use-after-free vulnerability. A local attacker in a guest VM
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2023-5633)
Budimir Markovic discovered that the perf subsystem in the Linux kernel did
not properly handle event groups, leading to an out-of-bounds write
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-5717)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 23.10:
linux-image-6.5.0-1010-gcp 6.5.0-1010.10
linux-image-gcp 6.5.0.1010.10
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

[USN-6463-2] Open VM Tools vulnerabilities
==========================================================================
Ubuntu Security Notice USN-6463-2
December 06, 2023
open-vm-tools vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS (Available with Ubuntu Pro)
- Ubuntu 16.04 LTS (Available with Ubuntu Pro)
Summary:
Several security issues were fixed in Open VM Tools.
Software Description:
- open-vm-tools: Open VMware Tools for virtual machines hosted on VMware
Details:
USN-6463-1 fixed vulnerabilities in Open VM Tools. This update provides
the corresponding updates for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.
Original advisory details:
It was discovered that Open VM Tools incorrectly handled SAML tokens. A
remote attacker with Guest Operations privileges could possibly use this
issue to elevate their privileges. (CVE-2023-34058)
Matthias Gerstner discovered that Open VM Tools incorrectly handled file
descriptors when dropping privileges. A local attacker could possibly use
this issue to hijack /dev/uinput and simulate user inputs.
(CVE-2023-34059)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 18.04 LTS (Available with Ubuntu Pro):
open-vm-tools 2:11.0.5-4ubuntu0.18.04.3+esm3
open-vm-tools-desktop 2:11.0.5-4ubuntu0.18.04.3+esm3
Ubuntu 16.04 LTS (Available with Ubuntu Pro):
open-vm-tools 2:10.2.0-3~ubuntu0.16.04.1+esm4
open-vm-tools-desktop 2:10.2.0-3~ubuntu0.16.04.1+esm4
In general, a standard system update will make all the necessary changes.

[USN-6535-1] curl vulnerabilities
==========================================================================
Ubuntu Security Notice USN-6535-1
December 06, 2023
curl vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 23.10
- Ubuntu 23.04
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in curl.
Software Description:
- curl: HTTP, HTTPS, and FTP client and client libraries
Details:
Harry Sintonen discovered that curl incorrectly handled mixed case cookie
domains. A remote attacker could possibly use this issue to set cookies
that get sent to different and unrelated sites and domains.
(CVE-2023-46218)
Maksymilian Arciemowicz discovered that curl incorrectly handled long file
names when saving HSTS data. This could result in curl losing HSTS data,
and subsequent requests to a site would be done without it, contrary to
expectations. This issue only affected Ubuntu 23.04 and Ubuntu 23.10.
(CVE-2023-46219)
