Amazon Linux AMI Security Advisory: ALAS-2019-1145
Advisory Release Date: 2019-01-09 22:47 Pacific
Advisory Updated Date: 2019-01-12 03:25 Pacific
Severity:
Medium
Issue Overview:
The USB subsystem mishandles size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c.(CVE-2018-20169)
A flaw was found where an attacker may be able to have an uncontrolled read to kernel-memory from within a vm guest. A race condition between connect() and close() function may allow an attacker using the AF_VSOCK protocol to gather a 4 byte information leak or possibly impersonate AF_VSOCK messages destined to other clients or leak kernel memory.(CVE-2018-14625)
