CVE-2010-4656

Published: 25 January 2011

The iowarrior_write function in drivers/usb/misc/iowarrior.c in the Linux kernel before 2.6.37 does not properly allocate memory, which might allow local users to trigger a heap-based buffer overflow, and consequently cause a denial of service or gain privileges, via a long report.

From the Ubuntu security team

Kees Cook discovered that the IOWarrior USB device driver did not correctly check certain size fields. A local attacker with physical access could plug in a specially crafted USB device to crash the system or potentially gain root privileges.
