USN-4394-1: SQLite vulnerabilities sqlite3 vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 20.04 LTS Ubuntu 19.10 Ubuntu 18.04 LTS Ubuntu 16.04 LTS Summary Several security issues were fixed in SQLite. Software Description sqlite3 – C library that implements an SQL database engine Details It was discovered that SQLite incorrectly handled certain corruped schemas. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-8740) It was discovered that SQLite incorrectly handled certain SELECT statements. An attacker could possibly use this issue to cause a denial of service. This issue was only addressed in Ubuntu 19.10. (CVE-2019-19603) It was discovered that SQLite incorrectly handled certain self-referential views. An attacker could possibly use this issue to cause a denial of service. This issue was only addressed in [ more… ]

USN-4393-1: Linux kernel vulnerabilities linux vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 12.04 ESM Summary Several security issues were fixed in the Linux kernel. Software Description linux – Linux kernel Details It was discovered that the Marvell WiFi-Ex Driver in the Linux kernel did not properly validate status lengths in messages received from an access point, leading to a buffer overflow. A physically proximate attacker controlling an access point could use this to construct messages that could possibly result in arbitrary code execution. (CVE-2020-12654) 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. [ more… ]

USN-4392-1: Linux kernel vulnerabilities linux, linux-lts-trusty vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 14.04 ESM Ubuntu 12.04 ESM Summary Several security issues were fixed in the Linux kernel. Software Description linux – Linux kernel linux-lts-trusty – Linux hardware enablement kernel from Trusty for Precise ESM Details It was discovered that the Marvell WiFi-Ex Driver in the Linux kernel did not properly validate status lengths in messages received from an access point, leading to a buffer overflow. A physically proximate attacker controlling an access point could use this to construct messages that could possibly result in arbitrary code execution. (CVE-2020-12654) 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 [ more… ]

USN-4391-1: Linux kernel vulnerabilities linux, linux-aws, linux-kvm vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 16.04 LTS Ubuntu 14.04 ESM Summary Several security issues were fixed in the Linux kernel. Software Description linux – Linux kernel linux-aws – Linux kernel for Amazon Web Services (AWS) systems linux-kvm – Linux kernel for cloud environments linux-lts-xenial – Linux hardware enablement kernel from Xenial for Trusty Details It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle setxattr operations in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-19319) 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 [ more… ]
