USN-4325-1: Linux kernel vulnerabilities linux-azure, linux-gcp, linux-gke-5.0, linux-oem-osp1, linux-oracle-5.0 vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 18.04 LTS Summary Several security issues were fixed in the Linux kernel. Software Description linux-azure – Linux kernel for Microsoft Azure Cloud systems linux-gcp – Linux kernel for Google Cloud Platform (GCP) systems linux-gke-5.0 – Linux kernel for Google Container Engine (GKE) systems linux-oem-osp1 – Linux kernel for OEM processors linux-oracle-5.0 – Linux kernel for Oracle Cloud systems Details It was discovered that the IPMI message handler implementation in the Linux kernel did not properly deallocate memory in certain situations. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19046) Al Viro discovered that the vfs layer in the Linux kernel contained a use- after-free vulnerability. A local attacker could use this [ more… ]

Software Description linux-aws – Linux kernel for Amazon Web Services (AWS) systems linux-gke-4.15 – Linux kernel for Google Container Engine (GKE) systems linux-kvm – Linux kernel for cloud environments linux-oem – Linux kernel for OEM processors linux-oracle – Linux kernel for Oracle Cloud systems linux-raspi2 – Linux kernel for Raspberry Pi 2 linux-snapdragon – Linux kernel for Snapdragon processors linux-aws-hwe – Linux kernel for Amazon Web Services (AWS-HWE) systems linux-azure – Linux kernel for Microsoft Azure Cloud systems linux-gcp – Linux kernel for Google Cloud Platform (GCP) systems Details Al Viro discovered that the vfs [ more… ]

USN-4323-1: Firefox vulnerabilities firefox vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 19.10 Ubuntu 18.04 LTS Ubuntu 16.04 LTS Summary Firefox could be made to crash or run programs as your login if it opened a malicious website. Software Description firefox – Mozilla Open Source web browser Details Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, or execute arbitrary code. (CVE-2020-6821, CVE-2020-6822, CVE-2020-6824, CVE-2020-6825, CVE-2020-6826) It was discovered that extensions could obtain auth codes from OAuth login flows in some circumstances. If a user were tricked in to installing a specially crafted extension, an attacker could potentially exploit this to obtain access to the user’s account. (CVE-2020-6823) Update instructions [ more… ]
