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 Fedora Local Security Checks NASL id FEDORA_2006-1470.NASL description This update rebases to 2.6.18.6rc2, which fixes the following security bugs : bridge: fix possible overflow in get_fdb_entries (CVE-2006-5751) Bluetooth: Add packet size checks for CAPI messages (CVE-2006-6106) In addition, a number of non-security related bugs have been fixed.

The clip_mkip function of the ATM subsystem in the 2.6 kernel allows remote attackers to dause a DoS (panic) via unknown vectors that cause the ATM subsystem to access the memory of socket buffers after they are freed (CVE-2006-4997). The NFS lockd in the 2.6 kernel before 2.6.16 allows remote attackers to cause a DoS (process crash) and deny access to NFS exports via unspecified vectors that trigger a kernel oops and a deadlock (CVE-2006-5158). The seqfile handling in the 2.6 kernel up to 2.6.18 allows local users to cause a DoS (hang or oops) via unspecified manipulations that trigger an infinite loop while searching for flowlabels (CVE-2006-5619). A missing call to init_timer() in the isdn_ppp code of the Linux kernel can allow remote attackers to send a special kind of PPP pakcet which may trigger a kernel oops (CVE-2006-5749). An integer overflow in the 2.6 kernel prior to 2.6.18.4 could allow a local user to execute arbitrary code via a large maxnum value in an ioctl request (CVE-2006-5751). A race condition in the ISO9660 filesystem handling could allow a local user to cause a DoS (infinite loop) by mounting a crafted ISO9660 filesystem containing malformed data structures (CVE-2006-5757). A vulnerability in the bluetooth support could allow for overwriting internal CMTP and CAPI data structures via malformed packets (CVE-2006-6106). 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 : - __bread oops fix - added e1000_ng (nineveh support) - added sata_svw (Broadcom SATA support) - added Marvell PATA chipset support - disabled mmconf on some broken hardware/BIOSes - use GENERICARCH and enable bigsmp apic model for tulsa machines 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 24628 published 2007-02-18 reporter This script is Copyright (C) 2007-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/24628 title Mandrake Linux Security Advisory : kernel (MDKSA-2007:012) 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.

In addition to these security fixes, other fixes have been included such as : - added the marvell IDE driver - use a specific driver Jmicron chipsets rather than using a generic one - updated the sky2 driver to fix some network hang issues 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 24619 published 2007-02-18 reporter This script is Copyright (C) 2007-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/24619 title Mandrake Linux Security Advisory : kernel (MDKSA-2007:002) NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2007-0014.NASL description From Red Hat Security Advisory 2007:0014 : Updated kernel packages that fix several security issues in the Red Hat Enterprise Linux 4 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 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 SuSE Local Security Checks NASL id SUSE_KERNEL-2705.NASL description This kernel update fixes the following security problems : - CVE-2006-5751: An integer overflow in the networking bridge ioctl starting with Kernel 2.6.7 could be used by local attackers to overflow kernel memory buffers and potentially escalate privileges [#222656] - CVE-2006-6106: Multiple buffer overflows in the cmtp_recv_interopmsg function in the Bluetooth driver (net/bluetooth/cmtp/capi.c) in the Linux kernel allowed remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via CAPI messages with a large value for the length of the (1) manu (manufacturer) or (2) serial (serial number) field. [#227603] - CVE-2006-5749: The isdn_ppp_ccp_reset_alloc_state function in drivers/isdn/isdn_ppp.c in the Linux kernel does not call the init_timer function for the ISDN PPP CCP reset state timer, which has unknown attack vectors and results in a system crash.
