CVE-2009-4005 kernel: isdn: hfc_usb: fix read buffer overflow
Last modified: 2012-07-16 13:04:36 EDT
The collect_rx_frame function in drivers/isdn/hisax/hfc_usb.c in the Linux kernel before 2.6.32-rc7 allows attackers to have an unspecified impact via a crafted HDLC packet that arrives over ISDN and triggers a buffer under-read.
Fixed in upstream kernels 220.127.116.11 and 18.104.22.168
kernel-22.214.171.124-170.2.117.fc10 has been submitted as an update for Fedora 10.
kernel-126.96.36.199-170.2.117.fc10 has been pushed to the Fedora 10 stable repository. If problems still persist, please make note of it in this bug report.
