CVE-2019-10193: Canonical Ubuntu Linux

High severity, CVSS 7.2. EPSS: 23.7% chance of exploitation in the next 30 days.

A stack-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x before 3.2.13, 4.x before 4.0.14 and 5.x before 5.0.4. By corrupting a hyperloglog using the SETRANGE command, an attacker could cause Redis to perform controlled increments of up to 12 bytes past the end of a stack-allocated buffer.
