Ubuntu Security Notice 6926-1 - 黄思聪 discovered that the NFC Controller Interface implementation in the Linux kernel did not properly handle certain memory allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service. It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6922-1 - It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service. Chenyuan Yang discovered that the Unsorted Block Images flash device volume management subsystem did not properly validate logical eraseblock sizes in certain situations. An attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 6920-1 - It was discovered that EDK II was not properly performing bounds checks in Tianocompress, which could lead to a buffer overflow. An authenticated user could use this issue to potentially escalate their privileges via local access. It was discovered that EDK II had an insufficient memory write check in the SMM service, which could lead to a page fault occurring. An authenticated user could use this issue to potentially escalate their privileges, disclose information and/or create a denial of service via local access.

Ubuntu Security Notice 6916-1 - It was discovered that Lua did not properly generate code when "_ENV" is constant. An attacker could possibly use this issue to cause a denial of service or execute arbitrary unstrusted lua code. It was discovered that Lua did not properly handle C stack overflows during error handling. An attacker could possibly use this issue to cause a denial of service.

Ubuntu Security Notice 6918-1 - It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 6919-1 - Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6917-1 - Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.

In snapd versions prior to 2.62, snapd failed to properly check the file type when extracting a snap. The snap format is a squashfs file-system image and so can contain files that are non-regular files (such as pipes or sockets etc). Various file entries within the snap squashfs image (such as icons etc) are directly read by snapd when it is extracted. An attacker who could convince a user to install a malicious snap which contained non-regular files at these paths could then cause snapd to block indefinitely trying to read from such files and cause a denial of service.

Ubuntu Security Notice 6915-1 - It was discovered that poppler incorrectly handled certain malformed PDF. An attacker could possibly use this issue to cause a denial of service.
