Ubuntu Security Notice 5618-1 - It was discovered the Ghostscript incorrectly handled memory when processing certain inputs. By tricking a user into opening a specially crafted PDF file, an attacker could cause the program to crash.

Grafana is an open-source platform for monitoring and observability. Versions prior to 9.1.6 and 8.5.13 are vulnerable to an escalation from admin to server admin when auth proxy is used, allowing an admin to take over the server admin account and gain full control of the grafana instance. All installations should be upgraded as soon as possible. As a workaround deactivate auth proxy following the instructions at: https://grafana.com/docs/grafana/latest/setup-grafana/configure-security/configure-authentication/auth-proxy/

A security issue was discovered in Z-BlogPHP <= 1.7.2. A Server-Side Request Forgery (SSRF) vulnerability in the zb_users/plugin/UEditor/php/action_crawler.php file allows remote attackers to force the application to make arbitrary requests via injection of arbitrary URLs into the source parameter.

Ubuntu Security Notice 5619-1 - It was discovered that LibTIFF was not properly performing the calculation of data that would eventually be used as a reference for bound-checking operations. An attacker could possibly use this issue to cause a denial of service or to expose sensitive information. This issue only affected Ubuntu 18.04 LTS. It was discovered that LibTIFF was not properly terminating a function execution when processing incorrect data. An attacker could possibly use this issue to cause a denial of service or to expose sensitive information. This issue only affected Ubuntu 18.04 LTS.

Blink1Control2 version 2.2.7 suffers from a weak password encryption vulnerability.

The OWASP ModSecurity Core Rule Set (CRS) is affected by a response body bypass to sequentially exfiltrate small and undetectable sections of data by repeatedly submitting an HTTP Range header field with a small byte range. A restricted resource, access to which would ordinarily be detected, may be exfiltrated from the backend, despite being protected by a web application firewall that uses CRS. Short subsections of a restricted resource may bypass pattern matching techniques and allow undetected access. The legacy CRS versions 3.0.x and 3.1.x are affected, as well as the currently supported versions 3.2.1 and 3.3.2. Integrators and users are advised to upgrade to 3.2.2 and 3.3.3 respectively and to configure a CRS paranoia level of 3 or higher.

Ubuntu Security Notice 5617-1 - It was discovered that memory contents previously stored in microarchitectural special registers after RDRAND, RDSEED, and SGX EGETKEY read operations on Intel client and Xeon E3 processors may be briefly exposed to processes on the same or different processor cores. A local attacker could use this to expose sensitive information. Julien Grall discovered that Xen incorrectly handled memory barriers on ARM-based systems. An attacker could possibly use this issue to cause a denial of service, obtain sensitive information or escalate privileges.

Ubuntu Security Notice 5613-2 - USN-5613-1 fixed vulnerabilities in Vim. Unfortunately that update failed to include binary packages for some architectures. This update fixes that regression. It was discovered that Vim was not properly performing bounds checks when executing spell suggestion commands. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. It was discovered that Vim was using freed memory when dealing with regular expressions through its old regular expression engine. If a user were tricked into opening a specially crafted file, an attacker could crash the application, leading to a denial of service, or possibly achieve code execution. It was discovered that Vim was not properly performing checks on name of lambda functions. An attacker could possibly use this issue to cause a denial of service. This issue affected only Ubuntu 22.04 LTS. It was discovered that Vim was incorrectly performing bounds checks when processing invalid...

Ubuntu Security Notice 5616-1 - Asaf Modelevsky discovered that the Intel 10GbE PCI Express Ethernet driver for the Linux kernel performed insufficient control flow management. A local attacker could possibly use this to cause a denial of service. Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information.

An issue was discovered in Bento4 through 1.6.0-639. There is a NULL pointer dereference in AP4_StszAtom::GetSampleSize.
