Detail
| A security issue affects the following Ubuntu releases: Ubuntu 6.06 LTS This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: After a standard system upgrade you need to reboot your computer to effect the necessary changes. Please note that Ubuntu 5.04 and 5.10 are also affected by these flaws. An update is in preparation and will be released shortly. Details follow: A Denial of service vulnerability was reported in iptables' SCTP conntrack module. On computers which use this iptables module, a remote attacker could expoit 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. |

| 27119 | Linux Kernel ftdi_sio Serial Port Data Saturation Local DoS The Linux kernel contains a flaw that may allow a local denial of service. The issue is triggered because the 'ftdi_sio' serial driver cannot handle data at the rate it can be queued for, which may lead to consumption of all system memory resulting in loss of availability for the platform. |
| 26963 | Linux Kernel SCTP conntrack Chunkless Packet Remote DoS Linux Kernel contains a flaw that may allow a remote denial of service. The issue is triggered when an error occurs when handling SCTP packets without a chunk, and will result in loss of availability for the platform. |
