Description

A Denial of service vulnerability was reported in iptables' SCTP conntrack module. On computers which use this iptables module, a remote attacker could exploit this to trigger a kernel crash. (CVE-2006-2934)

A buffer overflow has been discovered in the dvd_read_bca() function. By inserting a specially crafted DVD, USB stick, or similar automatically mounted removable device, a local user could crash the machine or potentially even execute arbitrary code with full root privileges. (CVE-2006-2935)

The ftdi_sio driver for serial USB ports did not limit the amount of pending data to be written. A local user could exploit this to drain all available kernel memory and thus render the system unusable. (CVE-2006-2936)

Additionally, this update fixes a range of bugs.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
