SUSE released a security update for multipath-tools addressing vulnerabilities in kpartx that could lead to memory issues through crafted disk images or devices.

Description

This update for multipath-tools fixes the following issues

* kpartx: integer overflow in the GPT partition table size calculation can

lead to heap OOB read via crafted USB device or disk image(bsc#1268145).

* kpartx: missing bounds check can lead to a DASD VOL1 unbounded array write

via a crafted DASD disk with more than 256 consecutive format labels

(bsc#1268144).
