USN-5943-1: Thunderbird vulnerabilities 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. (CVE-2023-0616, CVE-2023-25735, CVE-2023-25737, CVE-2023-25739, CVE-2023-25729, CVE-2023-25742, CVE-2023-25746) Johan Carlsson discovered that Thunderbird did not properly implement CSP policy on a header when using iframes. An attacker could potentially exploits this to exfiltrate data. (CVE-2023-25728) Irvan Kurniawan discovered that Thunderbird was not properly handling background fullscreen scripts when the window goes into fullscreen mode. An attacker could possibly use this issue to spoof the user and obtain sensitive information. (CVE-2023-25730) Christian Holler discovered that Thunderbird did not properly check the Safe Bag attributes in PKCS 12 certificate bundle. An attacker could possibly [ more… ]

USN-5944-1: SnakeYAML vulnerabilities It was discovered that SnakeYAML did not limit the maximal nested depth for collections when parsing YAML data. If a user or automated system were tricked into opening a specially crafted YAML file, an attacker could possibly use this issue to cause applications using SnakeYAML to crash, resulting in a denial of service. (CVE-2022-25857, CVE-2022-38749, CVE-2022-38750) It was discovered that SnakeYAML did not limit the maximal data matched with regular expressions when parsing YAML data. If a user or automated system were tricked into opening a specially crafted YAML file, an attacker could possibly use this issue to cause applications using SnakeYAML to crash, resulting in a denial of service. (CVE-2022-38751) Source: USN-5944-1: SnakeYAML vulnerabilities

USN-5942-1: Apache HTTP Server vulnerabilities Lars Krapf discovered that the Apache HTTP Server mod_proxy module incorrectly handled certain configurations. A remote attacker could possibly use this issue to perform an HTTP Request Smuggling attack. (CVE-2023-25690) Dimas Fariski Setyawan Putra discovered that the Apache HTTP Server mod_proxy_uwsgi module incorrectly handled certain special characters. A remote attacker could possibly use this issue to perform an HTTP Request Smuggling attack. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 22.10.
