Debian DSA-1304-1 : kernel-source-2.6.8 - several vulnerabilities
High Nessus Plugin ID 25529
The remote Debian host is missing a security-related update.
CVE-2006-6060 CVE-2006-6106 CVE-2006-6535 CVE-2007-0958 CVE-2007-1357 CVE-2007-1592 Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. This update also fixes a regression in the smbfs subsystem which was introduced in DSA-1233which caused symlinks to be interpreted as regular files. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2005-4811 David Gibson reported an issue in the hugepage code which could permit a local DoS (system crash) on appropriately configured systems. - CVE-2006-4814 Doug Chapman discovered a potential local DoS (deadlock) in the mincore function caused by improper lock handling. - CVE-2006-4623 Ang Way Chuang reported a remote DoS (crash) in the dvb driver which can be triggered by a ULE package with an SNDU length of 0. - CVE-2006-5753 Eric Sandeen provided a fix for a local memory corruption vulnerability resulting from a misinterpretation of return values when operating on inodes which have been marked bad. - CVE-2006-5754 Darrick Wong discovered a local DoS (crash) vulnerability resulting from the incorrect initialization of 'nr_pages' in aio_setup_ring(). - CVE-2006-5757 LMH reported a potential local DoS which could be exploited by a malicious user with the privileges to mount and read a corrupted iso9660 filesystem. - CVE-2006-6053 LMH reported a potential local DoS which could be exploited by a malicious user with the privileges to mount and read a corrupted ext3 filesystem. - CVE-2006-6056 LMH reported a potential local DoS which could be exploited by a malicious user with the privileges to mount and read a corrupted hfs filesystem on systems with SELinux hooks enabled (Debian does not enable SELinux by default). - CVE-2006-6060 LMH reported a potential local DoS (infinite loop) which could be exploited by a malicious user with the privileges to mount and read a corrupted NTFS filesystem. - CVE-2006-6106 Marcel Holtman discovered multiple buffer overflows in the Bluetooth subsystem which can be used to trigger a remote DoS (crash) and potentially execute arbitrary code. - CVE-2006-6535 Kostantin Khorenko discovered an invalid error path in dev_queue_xmit() which could be exploited by a local user to cause data corruption. - CVE-2007-0958 Santosh Eraniose reported a vulnerability that allows local users to read otherwise unreadable files by triggering a core dump while using PT_INTERP. This is related to CVE-2004-1073. - CVE-2007-1357 Jean Delvare reported a vulnerability in the appletalk subsystem. Systems with the appletalk module loaded can be triggered to crash by other systems on the local network via a malformed frame. - CVE-2007-1592 Masayuki Nakagawa discovered that flow labels were inadvertently being shared between listening sockets and child sockets. This defect can be exploited by local users to cause a DoS (Oops).
Upgrade the kernel package immediately and reboot the machine. If you have built a custom kernel from the kernel source package, you will need to rebuild to take advantage of these fixes. The following matrix explains which kernel version for which architecture fix the problems mentioned above : Debian 3.1 (sarge) Source 2.6.8-16sarge7 Alpha architecture 2.6.8-16sarge7 AMD64 architecture 2.6.8-16sarge7 HP Precision architecture 2.6.8-6sarge7 Intel IA-32 architecture 2.6.8-16sarge7 Intel IA-64 architecture 2.6.8-14sarge7 Motorola 680x0 architecture 2.6.8-4sarge7 PowerPC architecture 2.6.8-12sarge7 IBM S/390 architecture 2.6.8-5sarge7 Sun Sparc architecture 2.6.8-15sarge7
