CVE-2013-7027

Published: 9 December 2013

The ieee80211_radiotap_iterator_init function in net/wireless/radiotap.c in the Linux kernel before 3.11.7 does not check whether a frame contains any data outside of the header, which might allow attackers to cause a denial of service (buffer over-read) via a crafted header.

From the Ubuntu security team

Evan Huus reported a buffer overflow in the Linux kernel's radiotap header parsing. A remote attacker could cause a denial of service (buffer over- read) via a specially crafted header.
