Description

This security bulletin contains information about 1 security vulnerability.


1) Information disclosure (CVE-ID: CVE-2019-10639)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the possibility to extract the Kernel Address Space Layout Randomization (KASLR) kernel image offset of the affected software using the IP ID values that the kernel produces for connectionless protocols. A remote attacker can force the targeted system to send UDP or ICMP traffic to an attacker-controlled IP address and gain unauthorized access to sensitive information on the system.
