Ubuntu Security Notice 5632-1 - Sebastian Chnelik discovered that OAuthLib incorrectly handled certain redirect uris. A remote attacker could possibly use this issue to cause OAuthLib to crash, resulting in a denial of service.

Ubuntu Security Notice 5634-1 - Domingo Dirutigliano and Nicola Guerrera discovered that the netfilter subsystem in the Linux kernel did not properly handle rules that truncated packets below the packet header size. When such rules are in place, a remote attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 5633-1 - It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Duoming Zhou discovered that race conditions existed in the timer handling implementation of the Linux kernel's Rose X.25 protocol layer, resulting in use-after-free vulnerabilities. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 5630-1 - It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information.

Netgear Nighthawk AC1900 Smart WiFi Dual Band Gigabit Router R7000-V1.0.11.134_10.2.119 is vulnerable to Buffer Overflow via the wl binary in firmware. There is a stack overflow vulnerability caused by strncat

Netgear N300 wireless router wnr2000v4-V1.0.0.70 is vulnerable to Buffer Overflow via uhttpd. There is a stack overflow vulnerability caused by strcpy.

Netgear Nighthawk AC1900 Smart WiFi Dual Band Gigabit Router R7000-V1.0.11.134_10.2.119 is vulnerable to Buffer Overflow via the wl binary in firmware. There is a stack overflow vulnerability caused by strncpy.

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. An SMM callout vulnerability in the SMM driver in UsbLegacyControlSmm leads to possible arbitrary code execution in SMM and escalation of privileges. An attacker could overwrite the function pointers in the EFI_BOOT_SERVICES table before the USB SMI handler triggers. (This is not exploitable from code running in the operating system.)

Ubuntu Security Notice 5628-1 - It was discovered that etcd incorrectly handled certain specially crafted WAL files. An attacker could possibly use this issue to cause a denial of service. It was discovered that etcd incorrectly handled directory permissions when trying to create a directory that exists already. An attacker could possibly use this issue to obtain sensitive information. It was discovered that etcd incorrectly handled endpoint setup. An attacker could possibly use this issue to cause a denial of service.
