Summary
Race condition in the ia32 compatibility code for the execve system call in Linux kernel 2.4 before 2.4.31 and 2.6 before 2.6.6 allows local users to cause a denial of service (kernel panic) and possibly execute arbitrary code via a concurrent thread that increments a pointer count after the nargs function has counted the pointers, but before the count is copied from user space to kernel space, which leads to a buffer overflow.

NASL family SuSE Local Security Checks NASL id SUSE_SA_2005_044.NASL description The remote host is missing the patch for the advisory SUSE-SA:2005:044 (kernel). The Linux kernel is the core component of the Linux system. This update fixes various security as well as non-security problems discovered since the last round of kernel updates. Not all kernels are affected by all the problems, each of the problems has an affected note attached to it. The CAN-YYYY-NNNN IDs are Mitre CVE Candidate IDs, please see http://www.mitre.org for more information. The following security problems have been fixed: - local users could crash the system by causing stack fault exceptions (CVE-2005-1767) SUSE Linux 9.0 and SLES8 are affected. - local users could use ptrace to crash the kernel (CVE-2005-1761). SLES8 on the ia64 architecture is affected. - by causing an overflow in the 32bit execve function users could crash the kernel or even execute code (CVE-2005-1768). SLES 9 on the x86-64 and ia64 architectures and SUSE Linux 9.1 on the x86-64 architecture are affected. - an overflow when validating XDR data for the nfsacl protocol could crash the kernel. SUSE Linux 9.2 and 9.3 are affected. - local users could crash the kernel by reading from large offsets in sysfs files SUSE Linux 9.2 is affected. On SUSE Linux 9.1 this update contains the kernel used by the SUSE Linux Enterprise Server 9, Service Pack 2. This kernel adds among many bugfixes and driver updates support for non-executable pages (NX) on x86 CPUs and improves dual core CPU support. last seen 2019-10-28 modified 2005-08-04 plugin id 19382 published 2005-08-04 reporter This script is Copyright (C) 2005-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/19382 title SUSE-SA:2005:044: kernel NASL family Debian Local Security Checks NASL id DEBIAN_DSA-921.NASL 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-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 allows 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 a stack exception that will lead 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 crash 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. last seen 2020-06-01 modified 2020-06-02 plugin id 22787 published 2006-10-14 reporter This script is Copyright (C) 2006-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/22787 title Debian DSA-921-1 : kernel-source-2.4.27 - several vulnerabilities NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2005-663.NASL description Updated kernel packages are now available as part of ongoing support and maintenance of Red Hat Enterprise Linux version 3.
