Ubuntu Security Notice USN-6893-3

Ubuntu Security Notice 6893-3 - It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice USN-6896-5

Ubuntu Security Notice 6896-5 - It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the Atheros 802.11ac wireless driver did not properly validate certain data structures, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial of service.

GHSA-hcmv-jmqh-fjgm: ops leaking secrets if `subprocess.CalledProcessError` happens with a `secret-*` CLI command

### Summary The issue here is that we pass the secret content as one of the args via CLI. This issue may affect any of our charms that are using: Juju (>=3.0), Juju secrets and not correctly capturing and processing `subprocess.CalledProcessError`. There are two points that may log this command, in different files: First, if there is an error during a secret handling, there will be a `subprocess.CalledProcessError`, which will contain the CLI comand + all its args. This is going to be logged in any logging level. This exception, if not caught by the charm, will bubble up to the `/var/log/juju/` logs and syslog journal. Now, on Ubuntu 22.04, these logs are protected with: ``` $ juju ssh -m controller 0 -- ls -la /var/log/juju/ total 224 drwxr-xr-x 2 syslog adm 4096 Jul 14 10:59 . drwxrwxr-x 9 root syslog 4096 Jul 14 10:58 .. -rw-r----- 1 syslog adm 20124 Jul 14 11:10 audit.log -rw-r----- 1 syslog adm 110432 Jul 14 11:10 logsink.log -rw-r----- 1 syslog adm 80783 Ju...

Ubuntu Security Notice USN-6903-1

Ubuntu Security Notice 6903-1 - Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. Ronald Crane discovered that Thunderbird did not properly manage certain memory operations in the NSS. An attacker could potentially exploit this issue to cause a denial of service.

Ubuntu Security Notice USN-6898-3

Ubuntu Security Notice 6898-3 - Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.
