Ubuntu Security Notice 5948-1 - It was discovered that Werkzeug did not properly handle the parsing of nameless cookies. A remote attacker could possibly use this issue to shadow other cookies. It was discovered that Werkzeug could be made to process unlimited number of multipart form data parts. A remote attacker could possibly use this issue to cause Werkzeug to consume resources, leading to a denial of service.

Ubuntu Security Notice 5946-1 - Lai Han discovered that XStream incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. It was discovered that XStream incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.

Ubuntu Security Notice 5947-1 - Fabien Potencier discovered that Twig was not properly enforcing sandbox policies when dealing with objects automatically cast to strings by PHP.

Ubuntu Security Notice 5943-1 - 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. 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.

Ubuntu Security Notice 5941-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel did not properly handle VLAN headers in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5940-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the NVMe driver in the Linux kernel did not properly handle reset events in some situations. A local attacker could use this to cause a denial of service.

Docker Desktop before 4.17.0 allows an attacker to execute an arbitrary command inside a Dev Environments container during initialization by tricking an user to open a crafted malicious docker-desktop:// URL.

SQL Injection in GitHub repository unilogies/bumsys prior to v2.0.2.

Ubuntu Security Notice 5944-1 - 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. 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.
