Debian DSA-1503-1 : kernel-source-2.4.27 - several vulnerabilities

high Nessus Plugin ID 31147

Synopsis

The remote Debian host is missing a security-related update.

Description

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. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2004-2731 infamous41md reported multiple integer overflows in the Sbus PROM driver that would allow for a DoS (Denial of Service) attack by a local user, and possibly the execution of arbitrary code.

- CVE-2006-4814 Doug Chapman discovered a potential local DoS (deadlock) in the mincore function caused by improper lock handling.

- 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-2006-5823 LMH reported a potential local DoS which could be exploited by a malicious user with the privileges to mount and read a corrupted cramfs 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-2006-6054 LMH reported a potential local DoS which could be exploited by a malicious user with the privileges to mount and read a corrupted ext2 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-2007-1353 Ilja van Sprundel discovered that kernel memory could be leaked via the Bluetooth setsockopt call due to an uninitialized stack buffer. This could be used by local attackers to read the contents of sensitive kernel memory.

- 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).

- CVE-2007-2172 Thomas Graf reported a typo in the DECnet protocol handler that could be used by a local attacker to overrun an array via crafted packets, potentially resulting in a Denial of Service (system crash). A similar issue exists in the IPV4 protocol handler and will be fixed in a subsequent update.

- CVE-2007-2525 Florian Zumbiehl discovered a memory leak in the PPPOE subsystem caused by releasing a socket before PPPIOCGCHAN is called upon it. This could be used by a local user to DoS a system by consuming all available memory.

- CVE-2007-3848 Wojciech Purczynski discovered that pdeath_signal was not being reset properly under certain conditions which may allow local users to gain privileges by sending arbitrary signals to suid binaries.

- CVE-2007-4308 Alan Cox reported an issue in the aacraid driver that allows unprivileged local users to make ioctl calls which should be restricted to admin privileges.

- CVE-2007-4311 PaX team discovered an issue in the random driver where a defect in the reseeding code leads to a reduction in entropy.

- CVE-2007-5093 Alex Smith discovered an issue with the pwc driver for certain webcam devices. If the device is removed while a userspace application has it open, the driver will wait for userspace to close the device, resulting in a blocked USB subsystem. This issue is of low security impact as it requires the attacker to either have physical access to the system or to convince a user with local access to remove the device on their behalf.

- CVE-2007-6063 Venustech AD-LAB discovered a a buffer overflow in the isdn ioctl handling, exploitable by a local user.

- CVE-2007-6151 ADLAB discovered a possible memory overrun in the ISDN subsystem that may permit a local user to overwrite kernel memory by issuing ioctls with unterminated data.

- CVE-2007-6206 Blake Frantz discovered that when a core file owned by a non-root user exists, and a root-owned process dumps core over it, the core file retains its original ownership. This could be used by a local user to gain access to sensitive information.

- CVE-2007-6694 Cyrill Gorcunov reported a NULL pointer dereference in code specific to the CHRP PowerPC platforms. Local users could exploit this issue to achieve a Denial of Service (DoS).

- CVE-2008-0007 Nick Piggin of SuSE discovered a number of issues in subsystems which register a fault handler for memory mapped areas. This issue can be exploited by local users to achieve a Denial of Service (DoS) and possibly execute arbitrary code.

Solution

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.
