Summary
The copy_from_user function in the uaccess code in Linux kernel 2.6 before 2.6.19-rc1, when running on s390, does not properly clear a kernel buffer, which allows local user space programs to read portions of kernel memory by "appending to a file from a bad address," which triggers a fault that prevents the unused memory from being cleared in the kernel buffer.

NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2006-0710.NASL description Updated kernel packages that fix several security issues in the Red Hat Enterprise Linux 3 kernel are now available. This security advisory has been rated as having important security impact by the Red Hat Security Response Team. The Linux kernel handles the basic functions of the operating system. These new kernel packages contain fixes for the security issues described below : * a flaw in the IPC shared-memory implementation that allowed a local user to cause a denial of service (deadlock) that resulted in freezing the system (CVE-2006-4342, Important) * an information leak in the copy_from_user() implementation on s390 and s390x platforms that allowed a local user to read arbitrary kernel memory (CVE-2006-5174, Important) * a flaw in the ATM subsystem affecting systems with installed ATM hardware and configured ATM support that allowed a remote user to cause a denial of service (panic) by accessing socket buffer memory after it has been freed (CVE-2006-4997, Moderate) * a directory traversal vulnerability in smbfs that allowed a local user to escape chroot restrictions for an SMB-mounted filesystem via last seen 2020-06-01 modified 2020-06-02 plugin id 22918 published 2006-10-25 reporter This script is Copyright (C) 2006-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/22918 title RHEL 3 : kernel (RHSA-2006:0710) code #%NASL_MIN_LEVEL 80502 # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Red Hat Security Advisory RHSA-2006:0710.

The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2005-4093 Olof Johansson reported a local DoS (Denial of Service) vulnerability on the PPC970 platform. Unprivileged users can hang the system by executing the 'attn' instruction, which was not being disabled at boot. - CVE-2006-4538 Kirill Korotaev reported a local DoS (Denial of Service) vulnerability on the ia64 and sparc architectures. A user could cause the system to crash by executing a malformed ELF binary due to insufficient verification of the memory layout. - CVE-2006-4997 ADLab Venustech Info Ltd reported a potential remote DoS (Denial of Service) vulnerability in the IP over ATM subsystem. A remote system could cause the system to crash by sending specially crafted packets that would trigger an attempt to free an already-freed pointer resulting in a system crash. - CVE-2006-5174 Martin Schwidefsky reported a potential leak of sensitive information on s390 systems. The copy_from_user function did not clear the remaining bytes of the kernel buffer after receiving a fault on the userspace address, resulting in a leak of uninitialized kernel memory. A local user could exploit this by appending to a file from a bad address. - CVE-2006-5649 Fabio Massimo Di Nitto reported a potential remote DoS (Denial of Service) vulnerability on powerpc systems. The alignment exception only checked the exception table for -EFAULT, not for other errors. This can be exploited by a local user to cause a system crash (panic). - CVE-2006-5871 Bill Allombert reported that various mount options are ignored by smbfs when UNIX extensions are enabled. This includes the uid, gid and mode options. Client systems would silently use the server-provided settings instead of honoring these options, changing the security model. This update includes a fix from Haroldo Gamal that forces the kernel to honor these mount options. Note that, since the current versions of smbmount always pass values for these options to the kernel, it is not currently possible to activate unix extensions by omitting mount options. However, this behavior is currently consistent with the current behavior of the next Debian release, 'etch'." ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2005-4093" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2006-4538" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2006-4997" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2006-5174" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2006-5649" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2006-5871" ); script_set_attribute( attribute:"see_also", value:"http://www.debian.org/security/2006/dsa-1237" ); script_set_attribute( attribute:"solution", value: "Upgrade the kernel package immediately and reboot the machine.

The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2006-3741 Stephane Eranian discovered a local DoS (Denial of Service) vulnerability on the ia64 architecture. A local user could exhaust the available file descriptors by exploiting a counting error in the permonctl() system call. - CVE-2006-4538 Kirill Korotaev reported a local DoS (Denial of Service) vulnerability on the ia64 and sparc architectures. A user could cause the system to crash by executing a malformed ELF binary due to insufficient verification of the memory layout. - CVE-2006-4813 Dmitriy Monakhov reported a potential memory leak in the __block_prepare_write function. __block_prepare_write does not properly sanitize kernel buffers during error recovery, which could be exploited by local users to gain access to sensitive kernel memory. - CVE-2006-4997 ADLab Venustech Info Ltd reported a potential remote DoS (Denial of Service) vulnerability in the IP over ATM subsystem. A remote system could cause the system to crash by sending specially crafted packets that would trigger an attempt to free an already-freed pointer resulting in a system crash. - CVE-2006-5174 Martin Schwidefsky reported a potential leak of sensitive information on s390 systems. The copy_from_user function did not clear the remaining bytes of the kernel buffer after receiving a fault on the userspace address, resulting in a leak of uninitialized kernel memory. A local user could exploit this by appending to a file from a bad address. - CVE-2006-5619 James Morris reported a potential local DoS (Denial of Service) vulnerability that could be used to hang or oops a system. The seqfile handling for /proc/net/ip6_flowlabel has a flaw that can be exploited to cause an infinite loop by reading this file after creating a flowlabel. - CVE-2006-5649 Fabio Massimo Di Nitto reported a potential remote DoS (Denial of Service) vulnerability on powerpc systems. The alignment exception only checked the exception table for -EFAULT, not for other errors. This can be exploited by a local user to cause a system crash (panic). - CVE-2006-5751 Eugene Teo reported a vulnerability in the get_fdb_entries function that could potentially be exploited to allow arbitrary code execution with escalated privileges. - CVE-2006-5871 Bill Allombert reported that various mount options are ignored by smbfs when UNIX extensions are enabled. This includes the uid, gid and mode options. Client systems would silently use the server-provided settings instead of honoring these options, changing the security model. This update includes a fix from Haroldo Gamal that forces the kernel to honor these mount options. Note that, since the current versions of smbmount always pass values for these options to the kernel, it is not currently possible to activate unix extensions by omitting mount options. However, this behavior is currently consistent with the current behavior of the next Debian release, last seen 2020-06-01 modified 2020-06-02 plugin id 23846 published 2006-12-14 reporter This script is Copyright (C) 2006-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/23846 title Debian DSA-1233-1 : kernel-source-2.6.8 - several vulnerabilities NASL family SuSE Local Security Checks NASL id SUSE_KERNEL-DEBUG-2393.NASL description This kernel update fixes the following security problems : - A bug within the UDF filesystem that caused machine hangs when truncating files on the filesystem was fixed. [#186226]. (CVE-2006-4145) - A potential crash when receiving IPX packets was fixed. This problem is thought not to be exploitable. [#197809] - A problem in DVB packet handling could be used to crash the machine when receiving DVB net packages is active. [#201429]. (CVE-2006-4623) - A struct file leak was fixed in the perfmon(2) system call on the Itanium architecture. [#202269]. (CVE-2006-3741) - A malformed ELF image can be used on the Itanium architecture to trigger a kernel crash (denial of service) when a local attacker can supply it to be started. [#203822]. (CVE-2006-4538) - A problem in the ATM protocol handling clip_mkip function could be used by remote attackers to potentially crash the machine. [#205383]. (CVE-2006-4997) CVE-2006-5757/ - A problem in the grow_buffers function could be used to crash or hang the machine using a corrupted filesystem. This affects filesystem types ISO9660 and NTFS. [#205384]. (CVE-2006-6060) - On the i386 architecture the ELFAGS content was not correctly saved, which could be used by local attackers to crash other programs using the AC and NT flag or to escalate privileges by waiting for iopl privileges to be leaked. [#209386]. (CVE-2006-5173) - On the S/390 architecture copy_from_user() could be used by local attackers to read kernel memory. [#209880]. (CVE-2006-5174) - A problem in IPv6 flowlabel handling can be used by local attackers to hang the machine. [#216590]. (CVE-2006-5619) - On the PowerPC architecture a syscall has been wired without the proper futex implementation that can be exploited by a local attacker to hang the machine. [#217295]. (CVE-2006-5648) - On the PowerPC architecture the proper futex implementation was missing a fix for alignment check which could be used by a local attacker to crash the machine. [#217295]. (CVE-2006-5649) - A problem in cramfs could be used to crash the machine during mounting a crafted cramfs image. This requires an attacker to supply such a crafted image and have a user mount it. [#218237]. (CVE-2006-5823) - A problem in the ext3 filesystem could be used by attackers able to supply a crafted ext3 image to cause a denial of service or further data corruption if a user mounts this image. [#220288]. (CVE-2006-6053) - Missing return code checking in the HFS could be used to crash machine when a user complicit attacker is able to supply a specially crafted HFS image. [#221230]. (CVE-2006-6056) - Multiple unspecified vulnerabilities in netfilter for IPv6 code allow remote attackers to bypass intended restrictions via fragmentation attack vectors, aka (1) last seen 2020-06-01 modified 2020-06-02 plugin id 59162 published 2012-05-17 reporter This script is Copyright (C) 2012-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/59162 title SuSE 10 Security Update : Linux kernel (ZYPP Patch Number 2393) NASL family CentOS Local Security Checks NASL id CENTOS_RHSA-2006-0710.NASL description Updated kernel packages that fix several security issues in the Red Hat Enterprise Linux 3 kernel are now available.
