Ubuntu 18.04 LTS : Linux kernel (Raspberry Pi) vulnerabilities (USN-6979-1)

"The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6979-1 advisory. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws i...

In the Linux kernel before 5.1.7 a device can be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g. UDP and ICMP). When such traffic is sent to multiple destination IP addresses it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses.
