Summary

Buffer overflow in NFS readlink handling in the Linux Kernel 2.4 up to 2.4.31 allows remote NFS servers to cause a denial of service (crash) via a long symlink, which is not properly handled in (1) nfs2xdr.c or (2) nfs3xdr.c and causes a crash in the NFS client.

    descriptionSeveral security related problems have been discovered in the Linux kernel which may lead to a denial of service or even the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2005-4798 A buffer overflow in NFS readlink handling allows a malicious remote server to cause a denial of service. - CVE-2006-2935 Diego Calleja Garcia discovered a buffer overflow in the DVD handling code that could be exploited by a specially crafted DVD USB storage device to execute arbitrary code. - CVE-2006-1528 A bug in the SCSI driver allows a local user to cause a denial of service. - CVE-2006-2444 Patrick McHardy discovered a bug in the SNMP NAT helper that allows remote attackers to cause a denial of service. - CVE-2006-2446 A race condition in the socket buffer handling allows remote attackers to cause a denial of service. - CVE-2006-3745 Wei Wang discovered a bug in the SCTP implementation that allows local users to cause a denial of service and possibly gain root privileges. - CVE-2006-4535 David Miller reported a problem with the fix for CVE-2006-3745 that allows local users to crash the system via an SCTP socket with a certain SO_LINGER value. The following matrix explains which kernel version for which architecture fixes the problem mentioned above : stable (sarge) Source 2.4.27-10sarge4 Alpha architecture 2.4.27-10sarge4 ARM architecture 2.4.27-2sarge4 Intel IA-32 architecture 2.4.27-10sarge4 Intel IA-64 architecture 2.4.27-10sarge4 Motorola 680x0 architecture 2.4.27-3sarge4 MIPS architectures 2.4.27-10.sarge4.040815-1 PowerPC architecture 2.4.27-10sarge4 IBM S/390 2.4.27-2sarge4 Sun Sparc architecture 2.4.27-9sarge4 FAI 1.9.1sarge4 mindi-kernel 2.4.27-2sarge3 kernel-image-speakup-i386 2.4.27-1.1sarge3 systemimager 3.2.3-6sarge3

    descriptionUpdated kernel packages are now available as part of ongoing support and maintenance of Red Hat Enterprise Linux version 3. This is the seventh regular update. This security advisory has been rated as having moderate security impact by the Red Hat Security Response Team. The Linux kernel handles the basic functions of the operating system. This is the seventh regular kernel update to Red Hat Enterprise Linux 3. New features introduced by this update include : - addition of the bnx2, dell_rbu, and megaraid_sas device drivers - support for multi-core, multi-threaded Intel Itanium processors - upgrade of the SATA subsystem to include ATAPI and SMART support - optional tuning via the new numa_memory_allocator, arp_announce, and printk_ratelimit sysctls There were many bug fixes in various parts of the kernel. The ongoing effort to resolve these problems has resulted in a marked improvement in the reliability and scalability of Red Hat Enterprise Linux 3. There were numerous driver updates and security fixes (elaborated below). Other key areas affected by fixes in this update include the networking subsystem, the VM subsystem, NPTL handling, autofs4, the USB subsystem, CPU enumeration, and 32-bit-exec-mode handling on 64-bit architectures. The following device drivers have been upgraded to new versions : aacraid -------- 1.1.5-2412 bnx2 ----------- 1.4.30 (new) dell_rbu ------- 2.1 (new) e1000 ---------- 6.1.16-k3 emulex --------- 7.3.3 fusion --------- 2.06.16.02 ipmi ----------- 35.11 megaraid2 ------ v2.10.10.1 megaraid_sas --- 00.00.02.00 (new) tg3 ------------ 3.43RH The following security bugs were fixed in this update : - a flaw in gzip/zlib handling internal to the kernel that allowed a local user to cause a denial of service (crash) (CVE-2005-2458,low) - a flaw in ext3 EA/ACL handling of attribute sharing that allowed a local user to gain privileges (CVE-2005-2801, moderate) - a minor info leak with the get_thread_area() syscall that allowed a local user to view uninitialized kernel stack data (CVE-2005-3276, low) Note: The kernel-unsupported package contains various drivers and modules that are unsupported and therefore might contain security problems that have not been addressed. All Red Hat Enterprise Linux 3 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.

    descriptionThis advisory covers the S/390 components of the recent security update for the Linux 2.6.8 kernel that were missing due to technical problems. For reference, please see the text of the original advisory. Several security related problems have been discovered in the Linux kernel which may lead to a denial of service or even the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2004-2660 Toshihiro Iwamoto discovered a memory leak in the handling of direct I/O writes that allows local users to cause a denial of service. - CVE-2005-4798 A buffer overflow in NFS readlink handling allows a malicious remote server to cause a denial of service. - CVE-2006-1052 Stephen Smalley discovered a bug in the SELinux ptrace handling that allows local users with ptrace permissions to change the tracer SID to the SID of another process. - CVE-2006-1343 Pavel Kankovsky discovered an information leak in the getsockopt system call which can be exploited by a local program to leak potentially sensitive memory to userspace. - CVE-2006-1528 Douglas Gilbert reported a bug in the sg driver that allows local users to cause a denial of service by performing direct I/O transfers from the sg driver to memory mapped I/O space. - CVE-2006-1855 Mattia Belletti noticed that certain debugging code left in the process management code could be exploited by a local attacker to cause a denial of service. - CVE-2006-1856 Kostik Belousov discovered a missing LSM file_permission check in the readv and writev functions which might allow attackers to bypass intended access restrictions. - CVE-2006-2444 Patrick McHardy discovered a bug in the SNMP NAT helper that allows remote attackers to cause a denial of service. - CVE-2006-2446 A race condition in the socket buffer handling allows remote attackers to cause a denial of service. - CVE-2006-2935 Diego Calleja Garcia discovered a buffer overflow in the DVD handling code that could be exploited by a specially crafted DVD USB storage device to execute arbitrary code. - CVE-2006-2936 A bug in the serial USB driver has been discovered that could be exploited by a custom made USB serial adapter to consume arbitrary amounts of memory. - CVE-2006-3468 James McKenzie discovered a denial of service vulnerability in the NFS driver. When exporting an ext3 file system over NFS, a remote attacker could exploit this to trigger a file system panic by sending a specially crafted UDP packet. - CVE-2006-3745 Wei Wang discovered a bug in the SCTP implementation that allows local users to cause a denial of service and possibly gain root privileges. - CVE-2006-4093 Olof Johansson discovered that the kernel does not disable the HID0 bit on PowerPC 970 processors which could be exploited by a local attacker to cause a denial of service. - CVE-2006-4145 A bug in the Universal Disk Format (UDF) filesystem driver could be exploited by a local user to cause a denial of service. - CVE-2006-4535 David Miller reported a problem with the fix for CVE-2006-3745 that allows local users to crash the system via an SCTP socket with a certain SO_LINGER value.
