#vulnerability

Ubuntu Security Notice 6673-2 - USN-6673-1 provided a security update for python-cryptography. This update provides the corresponding update for Ubuntu 16.04 LTS. Hubert Kario discovered that python-cryptography incorrectly handled errors returned by the OpenSSL API when processing incorrect padding in RSA PKCS#1 v1.5. A remote attacker could possibly use this issue to expose confidential or sensitive information.

This post details the story and technical details of the non-secure Hypervisor-Protected Code Integrity (HVCI) configuration vulnerability disclosed and fixed with the January 9th update on Windows. This vulnerability, CVE-2024-21305, allowed arbitrary kernel-mode code execution, effectively bypassing HVCI within the root partition.

Fortinet FortiOS suffers from an out of bounds write vulnerability. Affected includes Fortinet FortiOS versions 7.4.0 through 7.4.2, 7.2.0 through 7.2.6, 7.0.0 through 7.0.13, 6.4.0 through 6.4.14, 6.2.0 through 6.2.15, 6.0.0 through 6.0.17, FortiProxy versions 7.4.0 through 7.4.2, 7.2.0 through 7.2.8, 7.0.0 through 7.0.14, 2.0.0 through 2.0.13, 1.2.0 through 1.2.13, 1.1.0 through 1.1.6, and 1.0.0 through 1.0.7.

Ubuntu Security Notice 6587-5 - USN-6587-1 fixed several vulnerabilities in X.Org. This update provides the corresponding update for Ubuntu 14.04 LTS. Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled memory when processing the RRChangeOutputProperty and RRChangeProviderProperty APIs. An attacker could possibly use this issue to cause the X Server to crash, or obtain sensitive information.

This Metasploit module exploits an authentication bypass vulnerability in JetBrains TeamCity. An unauthenticated attacker can leverage this to access the REST API and create a new administrator access token. This token can be used to upload a plugin which contains a Metasploit payload, allowing the attacker to achieve unauthenticated remote code execution on the target TeamCity server. On older versions of TeamCity, access tokens do not exist so the exploit will instead create a new administrator account before uploading a plugin. Older versions of TeamCity have a debug endpoint (/app/rest/debug/process) that allows for arbitrary commands to be executed, however recent version of TeamCity no longer ship this endpoint, hence why a plugin is leveraged for code execution instead, as this is supported on all versions tested.

Apple Security Advisory 03-12-2024-1 - GarageBand 10.4.11 addresses code execution and use-after-free vulnerabilities.

Ubuntu Security Notice 6686-2 - It was discovered that the DesignWare USB3 for Qualcomm SoCs driver in the Linux kernel did not properly handle certain error conditions during device registration. A local attacker could possibly use this to cause a denial of service. It was discovered that a race condition existed in the Cypress touchscreen driver in the Linux kernel during device removal, leading to a use-after- free vulnerability. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code.

Apple Security Advisory 03-07-2024-7 - visionOS 1.1 addresses buffer overflow, bypass, code execution, and out of bounds read vulnerabilities.

Backdoor.Win32.Emegrab.b malware suffers from a buffer overflow vulnerability.

StimulusReflex versions 3.5.0 up to and including 3.5.0.rc2 and 3.5.0.pre10 suffer from an arbitrary code execution vulnerability.
