Detail
| 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 Vulnerabilieis and Exposures project identifies the following problems: CVE-2005-0756 Alexander Nyberg discovered that the ptrace() system call does not properly verify addresses on the amd64 architecture which can be exploited by a local attacker to crash the kernel. CVE-2005-0757 A problem in the offset handling in the xattr file system code for ext3 has been discovered that may allow users on 64-bit systems that have access to an ext3 filesystem with extended attributes to cause the kernel to crash. CVE-2005-1762 A vulnerability has been discovered in the ptrace() system call on the amd64 architecture that allowas a local attacker to cause the kernel to crash. CVE-2005-1767 A vulnerability has been discovered in the stack segment fault handler that could allow a local attacker to cause stack exception that will leed the kernel to crash under certain circumstances. CVE-2005-1768 Ilja van Sprundel discovered a race condition in the IA32 (x86) compatibility execve() systemcall for amd64 and IA64 that allows local attackers to cause the kernel to panic and possibly execute arbitrary code. CVE-2005-2456 Balazs Scheidler discovered that a local attacker could call setsockopt() with an invalid xfrm_user policy message which would cause the kernel to write beyond the boundaries of an array and crash. CVE-2005-2458 Vladimir Volovich discovered a bug in the zlib routines which are also present in the Linux kernel and allows remote attackers to krash the kernel CVE-2005-2459 Another vulnerability has been discovered in the zlib routines which are also present in the Linux kernel and allows remote attackers to crash the kernel CVE-2005-2553 A null pointer dereference in ptrace when tracing a 64-bit executable can cause the kernel to crash. CVE-2005-2801 Andreas Gruenbacher discovered a bug in the ext2 and ext3 file systems. When data areas are to be shared among two inodes not all information were compared for equality, which could expose wrong ACLs for files. CVE-2005-2872 Chad Walstrom discovered that the ipt_recent kernel module to stop SSH bruteforce attacks could cause the kernel to crash on 64-bit architectures. CVE-2005-3275 An error in the NAT code allows remote attackers to cause a denial of service (memory corruption) by causing two packets for the same protocol to be NATed at the same time, which leads to memory corruption. The following matrix explains which kernel version for which architecture fix the problems mentioned above: Debian 3.1 (sarge) Source 2.4.27-10sarge1 Alpha architecture 2.4.27-10sarge1 ARM architecture 2.4.27-2sarge1 Intel IA-32 architecture 2.4.27-10sarge1 Intel IA-64 architecture 2.4.27-10sarge1 Motorola 680x0 architecture 2.4.27-3sarge1 Big endian MIPS architecture 2.4.27-10.sarge1.040815-1 Little endian MIPS architecture 2.4.27-10.sarge1.040815-1 PowerPC architecture 2.4.27-10sarge1 IBM S/390 architecture 2.4.27-2sarge1 Sun Sparc architecture 2.4.27-9sarge1 We recommend that you upgrade your kernel package immediately and reboot the machine. |
