Vigil@nce - Linux kernel: denial of service via radiotap
December 2013 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can use the radiotap feature of the Linux kernel, in
order to trigger a denial of service.
– Impacted products: Linux
– Severity: 2/4
– Creation date: 02/12/2013
DESCRIPTION OF THE VULNERABILITY
The radiotap feature is used to inject and read IEEE 802.11 frames.
The ieee80211_radiotap_iterator_init() function does not check if
the data size is too large. It then tries to write 4 bytes at a
read-only memory address.
An attacker can therefore use the radiotap feature of the Linux
kernel, in order to trigger a denial of service.
