Linux Kernel Function Packet Handling Remote Buffer Overflow

high Log Correlation Engine Plugin ID 801970
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The host is using a Linux kernel which is vulnerable to a buffer overflow attack.

Description

Linux Kernel contains an overflow condition in the usbip_recv_xbuff() function in drivers/usb/usbip/usbip_common.c. The issue is triggered as user-supplied input is not properly validated when handling a crafted packet. This may allow a remote attacker to cause a buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.

Solution

Upgrade to Linux kernel 4.5.2-1 or later.
