Ubuntu Security Notice 5990-1 - It was discovered that musl did not handle certain i386 math functions properly. An attacker could use this vulnerability to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM, and Ubuntu 18.04 LTS. It was discovered that musl did not handle wide-character conversion properly. A remote attacker could use this vulnerability to cause resource consumption , denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS.

Ubuntu Security Notice 5989-1 - Tao Lyu discovered that GlusterFS did not properly handle certain event notifications. An attacker could possibly use this issue to cause a denial of service.

Ubuntu Security Notice 5988-1 - It was discovered that integer overflows vulnerabilities existed in Xcftools. An attacker could use this to cause a denial of service or possibly execute arbitrary code.

A ReDoS issue was discovered in the Time component through 0.2.1 in Ruby through 3.2.1. The Time parser mishandles invalid URLs that have specific characters. It causes an increase in execution time for parsing strings to Time objects. The fixed versions are 0.1.1 and 0.2.2.

ZCBS Zijper Collectie Beheer Systeem (ZCBS), Zijper Publication Management System (ZPBS), and Zijper Image Bank Management System (ZBBS) 4.14k is vulnerable to Cross Site Scripting (XSS).

Ubuntu Security Notice 5986-1 - Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled certain memory operations. An attacker could possibly use these issues to cause the X Server to crash, execute arbitrary code, or escalate privileges.

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 (system crash) or possibly execute arbitrary code. It was discovered that the Upper Level Protocol (ULP) 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 (system crash) or possibly execute arbitrary code.

Ubuntu Security Notice 5985-1 - It was discovered that the System V IPC implementation in the Linux kernel did not properly handle large shared memory counts. A local attacker could use this to cause a denial of service. It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs.

Ubuntu Security Notice 5987-1 - It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. It was discovered that a use-after-free vulnerability existed in the SGI GRU driver in the Linux kernel. A local attacker could possibly use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5983-1 - Cyku Hong discovered that Nette was not properly handling and validating data used for code generation. A remote attacker could possibly use this issue to execute arbitrary code.
