Ubuntu Security Notice USN-7582-2
June 30, 2025
samba regression
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
Summary:
USN-7582-1 introduced a regression in Samba.
Software Description:
- samba: SMB/CIFS file, print, and login server for Unix
Details:
USN-7582-1 fixed vulnerabilities in Samba. The update introduced a
regression. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
Evgeny Legerov discovered that Samba incorrectly handled buffers in
certain GSSAPI routines of Heimdal. A remote attacker could possibly use
this issue to cause Samba to crash, resulting in a denial of service.
(CVE-2022-3437)
Greg Hudson discovered that Samba incorrectly handled PAC parsing. On
32-bit systems, a remote attacker could use this issue to escalate
privileges, or possibly execute arbitrary code. (CVE-2022-42898)
Joseph Sutton discovered that Samba could be forced to issue rc4-hmac
encrypted Kerberos tickets. A remote attacker could possibly use this
issue to escalate privileges. This issue only affected Ubuntu 20.04 LTS
and Ubuntu 22.04 LTS. (CVE-2022-45141)
Florent Saudel discovered that Samba incorrectly handled certain Spotlight
requests. A remote attacker could possibly use this issue to cause Samba
to consume resources, leading to a denial of service. (CVE-2023-34966)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 18.04 LTS
samba 2:4.7.6+dfsg~ubuntu-0ubuntu2.29+esm2
Available with Ubuntu Pro
Ubuntu 16.04 LTS
samba 2:4.3.11+dfsg-0ubuntu0.16.04.34+esm3
Available with Ubuntu Pro
Ubuntu 14.04 LTS
samba 2:4.3.11+dfsg-0ubuntu0.14.04.20+esm14
Available with Ubuntu Pro
In general, a standard system update will make all the necessary changes.

Ubuntu Security Notice USN-7605-1
June 30, 2025
linux, linux-aws, linux-gcp, linux-gcp-6.11, linux-hwe-6.11, linux-oracle,
linux-raspi, linux-realtime vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 24.10
- Ubuntu 24.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux: Linux kernel
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-realtime: Linux kernel for Real-time systems
- linux-gcp-6.11: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe-6.11: Linux hardware enablement (HWE) kernel
Details:
It was discovered that the CIFS network file system implementation in the
Linux kernel did not properly verify the target namespace when handling
upcalls. An attacker could use this to expose sensitive information.
(CVE-2025-2312)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

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-7604-1] Sudo vulnerabilities
==========================================================================
Ubuntu Security Notice USN-7604-1
June 30, 2025
sudo vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 25.04
- Ubuntu 24.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in Sudo.
Software Description:
- sudo: Provide limited super user privileges to specific users
Details:
Rich Mirch discovered that Sudo incorrectly handled the host option. In
environments where per-host rules are configured in the sudoers file, a
local attacker could use this issue to bypass the host restrictions.
(CVE-2025-32462)
Rich Mirch discovered that Sudo incorrectly handled the chroot option. In
environments where the sudoers file is configured to allow the chroot
option, a local attacker could use this issue to run arbitrary commands as
root. This issue only applied to Ubuntu 24.04 LTS, Ubuntu 24.10, and
Ubuntu 25.04. (CVE-2025-32463)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 25.04
sudo 1.9.16p2-1ubuntu1.1
sudo-ldap 1.9.16p2-1ubuntu1.1
Ubuntu 24.10
sudo 1.9.15p5-3ubuntu5.24.10.1
sudo-ldap 1.9.15p5-3ubuntu5.24.10.1
Ubuntu 24.04 LTS
sudo 1.9.15p5-3ubuntu5.24.04.1
sudo-ldap 1.9.15p5-3ubuntu5.24.04.1
Ubuntu 22.04 LTS
sudo 1.9.9-1ubuntu2.5
sudo-ldap 1.9.9-1ubuntu2.5
In general, a standard system update will make all the necessary changes.
