By sending specially crafted packets, a remote attacker could exploit this to bypass firewall rules. This has has already been fixed for Ubuntu 6.10 in USN-395-1; this is the corresponding fix for Ubuntu 6.06.(CVE-2006-4572) Doug Chapman discovered an improper lock handling in the mincore() function. A local attacker could exploit this to cause an eternal hang in the kernel, rendering the machine unusable. (CVE-2006-4814) Al Viro reported that the ISDN PPP module did not initialize the reset state timer. By sending specially crafted ISDN packets, a remote attacker could exploit this to crash the kernel. (CVE-2006-5749) Various syscalls (like listxattr()) misinterpreted the return value of return_EIO() when encountering bad inodes. By issuing particular system calls on a malformed file system, a local attacker could exploit this to crash the kernel. (CVE-2006-5753) The task switching code did not save and restore EFLAGS of processes. By starting a specially crafted executable, a local attacker could exploit this to eventually crash many other running processes. This only affects the amd64 platform. (CVE-2006-5755) A race condition was found in the grow_buffers() function. By mounting a specially crafted ISO9660 or NTFS file system, a local attacker could exploit this to trigger an infinite loop in the kernel, rendering the machine unusable. (CVE-2006-5757) A buffer overread was found in the zlib_inflate() function. By tricking an user into mounting a specially crafted file system which uses zlib compression (such as cramfs), this could be exploited to crash the kernel. (CVE-2006-5823) The ext3 file system driver did not properly handle corrupted data structures. By mounting a specially crafted ext3 file system, a local attacker could exploit this to crash the kernel. (CVE-2006-6053) The ext2 file system driver did not properly handle corrupted data structures. By mounting a specially crafted ext2 file system, a local attacker could exploit this to crash the kernel. (CVE-2006-6054) The hfs file system driver did not properly handle corrupted data structures. By mounting a specially crafted hfs file system, a local attacker could exploit this to crash the kernel. This only affects systems which enable SELinux (Ubuntu disables SELinux by default). (CVE-2006-6056) Several vulnerabilities have been found in the GFS2 file system driver. Since this driver has never actually worked in Ubuntu 6.10, it has been disabled. This only affects Ubuntu 6.10. (CVE-2006-6057) Marcel Holtman discovered several buffer overflows in the Bluetooth driver. By sending Bluetooth packets with specially crafted CAPI messages, a remote attacker could exploit these to crash the kernel. (CVE-2006-6106).

The zlib_inflate function allows local users to cause a crash via a malformed filesystem that uses zlib compression that triggers memory corruption (CVE-2006-5823). The key serial number collision avoidance code in the key_alloc_serial function in kernels 2.6.9 up to 2.6.20 allows local users to cause a crash via vectors thatr trigger a null dereference (CVE-2007-0006). The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels immediately and reboot to effect the fixes. In addition to these security fixes, other fixes have been included such as : - New drivers: nozomi, UVC - Fixed SiS SATA support for chips on 966/968 bridges - Fixed issues in squashfs by updating to 3.2 (#27008) - Added support for SiS968 bridgest to the sis190 bridge - Fixed JMicron cable detection - Added /proc/config.gz support and enabled kexec on x86_64 - Other minor fixes To update your kernel, please follow the directions located at : http://www.mandriva.com/en/security/kernelupdate last seen 2020-06-01 modified 2020-06-02 plugin id 24689 published 2007-02-22 reporter This script is Copyright (C) 2007-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/24689 title Mandrake Linux Security Advisory : kernel (MDKSA-2007:047) NASL family Debian Local Security Checks NASL id DEBIAN_DSA-1504.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-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-2006-6054 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-2006-6058 LMH reported an issue in the minix filesystem that allows local users with mount privileges to create a DoS (printk flood) by mounting a specially crafted corrupt filesystem. - CVE-2006-7203 OpenVZ Linux kernel team reported an issue in the smbfs filesystem which can be exploited by local users to cause a DoS (oops) during mount. - 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-2007-2172 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-2007-3105 The PaX Team discovered a potential buffer overflow in the random number generator which may permit local users to cause a denial of service or gain additional privileges. This issue is not believed to effect default Debian installations where only root has sufficient privileges to exploit it. - CVE-2007-3739 Adam Litke reported a potential local denial of service (oops) on powerpc platforms resulting from unchecked VMA expansion into address space reserved for hugetlb pages. - CVE-2007-3740 Steve French reported that CIFS filesystems with CAP_UNIX enabled were not honoring a process last seen 2020-06-01 modified 2020-06-02 plugin id 31148 published 2008-02-25 reporter This script is Copyright (C) 2008-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/31148 title Debian DSA-1504-1 : 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.

These new kernel packages contain fixes for the security issues described below : * a flaw in the get_fdb_entries function of the network bridging support that allowed a local user to cause a denial of service (crash) or allow a potential privilege escalation (CVE-2006-5751, Important) * an information leak in the _block_prepare_write function that allowed a local user to read kernel memory (CVE-2006-4813, Important) * an information leak in the copy_from_user() implementation on s390 and s390x platforms that allowed a local user to read kernel memory (CVE-2006-5174, Important) * a flaw in the handling of /proc/net/ip6_flowlabel that allowed a local user to cause a denial of service (infinite loop) (CVE-2006-5619, Important) * a flaw in the AIO handling that allowed a local user to cause a denial of service (panic) (CVE-2006-5754, Important) * a race condition in the mincore system core that allowed a local user to cause a denial of service (system hang) (CVE-2006-4814, Moderate) * a flaw in the ELF handling on ia64 and sparc architectures which triggered a cross-region memory mapping and allowed a local user to cause a denial of service (CVE-2006-4538, Moderate) * a flaw in the dev_queue_xmit function of the network subsystem that allowed a local user to cause a denial of service (data corruption) (CVE-2006-6535, Moderate) * a flaw in the handling of CAPI messages over Bluetooth that allowed a remote system to cause a denial of service or potential code execution. This flaw is only exploitable if a privileged user establishes a connection to a malicious remote device (CVE-2006-6106, Moderate) * a flaw in the listxattr system call that allowed a local user to cause a denial of service (data corruption) or potential privilege escalation. To successfully exploit this flaw the existence of a bad inode is required first (CVE-2006-5753, Moderate) * a flaw in the __find_get_block_slow function that allowed a local privileged user to cause a denial of service (CVE-2006-5757, Low) * various flaws in the supported filesystems that allowed a local privileged user to cause a denial of service (CVE-2006-5823, CVE-2006-6053, CVE-2006-6054, CVE-2006-6056, Low) In addition to the security issues described above, fixes for the following bugs were included : * initialization error of the tg3 driver with some BCM5703x network card * a memory leak in the audit subsystem * x86_64 nmi watchdog timeout is too short * ext2/3 directory reads fail intermittently Red Hat would like to thank Dmitriy Monakhov and Kostantin Khorenko for reporting issues fixed in this erratum. All Red Hat Enterprise Linux 4 users are advised to upgrade their kernels to the packages associated with their machine architecture and configurations as listed in this erratum. last seen 2020-06-01 modified 2020-06-02 plugin id 67438 published 2013-07-12 reporter This script is Copyright (C) 2013-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/67438 title Oracle Linux 4 : kernel (ELSA-2007-0014) NASL family Debian Local Security Checks NASL id DEBIAN_DSA-1503.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-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.

| statement | The CVE-2006-5823 is about a corrupted cramfs (MOKB-07-11-2006) that can cause a memory corruption and so crash the machine. For Red Hat Enterpise Linux 3 this issue is tracked via Bugzilla #216960 and for Red Hat Enterprise Linux 4 it is tracked via Bugzilla #216958. Red Hat Enterprise Linux 2.1 is not vulnerable to this issue. This issue has been rated as having low impact, because root privileges or physical access to the machine are needed to mount a corrupted filesystem and crash the machine. Red Hat Enterprise Linux 5 is not vulnerable to this issue as it contains a backported patch. |
