The remote host is missing an update to linux-2.6 announced via advisory DSA 2153-1.

CVE-2010-0435 Gleb Napatov reported an issue in the KVM subsystem that allows virtual machines to cause a denial of service of the host machine. CVE-2010-3699 Keir Fraser provided a fix for an issue in the Xen subsystem. CVE-2010-4158 Dan Rosenberg discovered an issue in the socket filters subsystem. CVE-2010-4162 Dan Rosenberg discovered an overflow issue in the block I/O subsystem. CVE-2010-4163 Dan Rosenberg discovered an issue in the block I/O subsystem. CVE-2010-4242 Alan Cox reported an issue in the Bluetooth subsystem. CVE-2010-4243 Brad Spengler reported a denial-of-service issue in the kernel memory accounting system. CVE-2010-4248 Oleg Nesterov reported an issue in the POSIX CPU timers subsystem. CVE-2010-4249 Vegard Nossum reported an issue with the UNIX socket garbage collector. CVE-2010-4258 Nelson Elhage reported an issue in Linux oops handling. CVE-2010-4342 Nelson Elhage reported an issue in the econet protocol. CVE-2010-4346 Tavis Ormandy discovered an issue in the install_special_mapping routine which allows local users to bypass the mmap_min_addr security restriction. CVE-2010-4526 Eugene Teo reported a race condition in the Linux SCTP implementation. CVE-2010-4527 Dan Rosenberg reported two issues in the OSS soundcard driver. Local users with access to the device (members of group 'audio' on default Debian installations) may contain access to sensitive kernel memory or cause a buffer overflow. CVE-2010-4529 Dan Rosenberg reported an issue in the Linux kernel IrDA socket implementation on non-x86 architectures. Local users may be able to gain access to sensitive kernel memory via a specially crafted IRLMP_ENUMDEVICES getsockopt call. CVE-2010-4565 Dan Rosenberg reported an issue in the Linux CAN protocol implementation. Local users can obtain the address of a kernel heap object which might help facilitate system exploitation. CVE-2010-4649 Dan Carpenter reported an issue in the uverb handling of the InfiniBand subsystem. A potential buffer overflow may allow local users to cause a denial of service (memory corruption) by passing in a large cmd.ne value. CVE-2010-4656 Kees Cook reported an issue in the driver for I/O-Warrior USB devices. Local users with access to these devices maybe able to overrun kernel buffers, resulting in a denial of service or privilege escalation. CVE-2010-4668 Dan Rosenberg reported an issue in the block subsystem. A local user can cause a denial of service (kernel panic) by submitting certain 0-length I/O requests. CVE-2011-0521 Dan Carpenter reported an issue in the DVB driver for AV7110 cards. Local users can pass a negative info->num value, corrupting kernel memory and causing a denial of service. For the stable distribution (lenny), this problem has been fixed in version 2.6.26-26lenny2.

We recommend that you upgrade your system to version '2.6.26-26lenny2' or later.
