Summary
Race condition in run_posix_cpu_timers in Linux kernel before 2.6.16.21 allows local users to cause a denial of service (BUG_ON crash) by causing one CPU to attach a timer to a process that is exiting.

NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-311-1.NASL description A race condition was discovered in the do_add_counters() functions. Processes which do not run with full root privileges, but have the CAP_NET_ADMIN capability can exploit this to crash the machine or read a random piece of kernel memory. In Ubuntu there are no packages that are affected by this, so this can only be an issue for you if you use third-party software that uses Linux capabilities. (CVE-2006-0039) John Stultz discovered a faulty BUG_ON trigger in the handling of POSIX timers. A local attacker could exploit this to trigger a kernel oops and crash the machine. (CVE-2006-2445) Dave Jones discovered that the PowerPC kernel did not perform certain required access_ok() checks. A local user could exploit this to read arbitrary kernel memory and crash the kernel on 64-bit systems, and possibly read arbitrary kernel memory on 32-bit systems. (CVE-2006-2448) A design flaw was discovered in the prctl(PR_SET_DUMPABLE, ...) system call, which allowed a local user to have core dumps created in a directory he could not normally write to. This could be exploited to drain available disk space on system partitions, or, under some circumstances, to execute arbitrary code with full root privileges. This flaw only affects Ubuntu 6.06 LTS. (CVE-2006-2451) In addition, the Ubuntu 6.06 LTS update fixes a range of bugs. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 27886 published 2007-11-10 reporter Ubuntu Security Notice (C) 2006-2019 Canonical, Inc. / NASL script (C) 2007-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/27886 title Ubuntu 5.04 / 5.10 / 6.06 LTS : linux-source-2.6.10/-2.6.12/-2.6.15 vulnerabilities (USN-311-1) code #%NASL_MIN_LEVEL 80502 # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Ubuntu Security Notice USN-311-1.

Prior to 2.6.16, a directory traversal vulnerability in CIFS could allow a local user to escape chroot restrictions for an SMB-mounted filesystem via '..\' sequences (CVE-2006-1863). Prior to 2.6.16, a directory traversal vulnerability in smbfs could allow a local user to escape chroot restrictions for an SMB-mounted filesystem via '..\' sequences (CVE-2006-1864). Prior to to 2.6.16.23, SCTP conntrack in netfilter allows remote attackers to cause a DoS (crash) via a packet without any chunks, causing a variable to contain an invalid value that is later used to dereference a pointer (CVE-2006-2934). The dvd_read_bca function in the DVD handling code assigns the wrong value to a length variable, which could allow local users to execute arbitrary code via a crafted USB storage device that triggers a buffer overflow (CVE-2006-2935). Prior to 2.6.17, the ftdi_sio driver could allow local users to cause a DoS (memory consumption) by writing more data to the serial port than the hardware can handle, causing the data to be queued (CVE-2006-2936). The 2.6 kernel, when using both NFS and EXT3, allowed remote attackers to cause a DoS (file system panic) via a crafted UDP packet with a V2 lookup procedure that specifies a bad file handle (inode number), triggering an error and causing an exported directory to be remounted read-only (CVE-2006-3468). The 2.6 kernel's SCTP was found to cause system crashes and allow for the possibility of local privilege escalation due to a bug in the get_user_iov_size() function that doesn't properly handle overflow when calculating the length of iovec (CVE-2006-3745).

NASL family Mandriva Local Security Checks NASL id MANDRAKE_MDKSA-2006-123.NASL description A number of vulnerabilities were discovered and corrected in the Linux 2.6 kernel : The kernel did not clear sockaddr_in.sin_zero before returning IPv4 socket names for the getsockopt function, which could allow a local user to obtain portions of potentially sensitive memory if getsockopt() is called with SO_ORIGINAL_DST (CVE-2006-1343). Prior to 2.6.16, a buffer overflow in the USB Gadget RNDIS implementation could allow a remote attacker to cause a Denial of Service via a remote NDIS response (CVE-2006-1368). Prior to 2.6.13, local users could cause a Denial of Service (crash) via a dio transfer from the sg driver to memory mapped IO space (CVE-2006-1528). Prior to and including 2.6.16, the kernel did not add the appropriate LSM file_permission hooks to the readv and writev functions, which could allow an attacker to bypass intended access restrictions (CVE-2006-1856). Prior to 2.6.16.17, a buffer oveflow in SCTP could allow a remote attacker to cause a DoS (crash) and possibly execute arbitrary code via a malformed HB-ACK chunk (CVE-2006-1857). Prior to 2.6.16.17, SCTP could allow a remote attacker to cause a DoS (crash) and possibly execute arbitrary code via a chunk length that is inconsistent with the actual length of provided parameters (CVE-2006-1858). Prior to 2.6.16.16, a memory leak in fs/locks.c could allow an attacker to cause a DoS (memory consumption) via unspecified actions (CVE-2006-1859). Prior to 2.6.16.16, lease_init in fs/locks.c could allow an attacker to cause a DoS (fcntl_setlease lockup) via certain actions (CVE-2006-1860). Prior to 2.6.17, SCTP allowed remote attackers to cause a DoS (infinite recursion and crash) via a packet that contains two or more DATA fragments (CVE-2006-2274). Prior to 2.6.16.21, a race condition in run_posix_cpu timers could allow a local user to cause a DoS (BUG_ON crash) by causing one CPU to attach a timer to a process that is exiting (CVE-2006-2445). Prior to 2.6.17.1, xt_sctp in netfilter could allow an attacker to cause a DoS (infinite loop) via an SCTP chunk with a 0 length (CVE-2006-3085). As well, an issue where IPC could hit an unmapped vmalloc page when near the page boundary has been corrected. In addition to these security fixes, other fixes have been included such as : - avoid automatic update of kernel-source without updating the kernel - fix USB EHCI handoff code, which made some machines hang while booting - disable USB_BANDWIDTH which corrects a known problem in some USB sound devices - fix a bluetooth refcounting bug which could hang the machine - fix a NULL pointer dereference in USB-Serial last seen 2020-06-01 modified 2020-06-02 plugin id 22058 published 2006-07-18 reporter This script is Copyright (C) 2006-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/22058 title Mandrake Linux Security Advisory : kernel (MDKSA-2006:123) code #%NASL_MIN_LEVEL 80502 # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Mandrake Linux Security Advisory MDKSA-2006:123. # The text itself is copyright (C) Mandriva S.A. # if (NASL_LEVEL < 3000) exit(0); include("compat.inc"); if (description) { script_id(22058); script_version ("1.16"); script_cvs_date("Date: 2019/08/02 13:32:48"); script_cve_id("CVE-2006-1342", "CVE-2006-1343", "CVE-2006-1368", "CVE-2006-1528", "CVE-2006-1856", "CVE-2006-1857", "CVE-2006-1858", "CVE-2006-1859", "CVE-2006-1860", "CVE-2006-2274", "CVE-2006-2445", "CVE-2006-3085"); script_xref(name:"MDKSA", value:"2006:123"); script_name(english:"Mandrake Linux Security Advisory : kernel (MDKSA-2006:123)"); script_summary(english:"Checks rpm output for the updated packages"); script_set_attribute( attribute:"synopsis", value: "The remote Mandrake Linux host is missing one or more security updates." ); script_set_attribute( attribute:"description", value: "A number of vulnerabilities were discovered and corrected in the Linux 2.6 kernel : The kernel did not clear sockaddr_in.sin_zero before returning IPv4 socket names for the getsockopt function, which could allow a local user to obtain portions of potentially sensitive memory if getsockopt() is called with SO_ORIGINAL_DST (CVE-2006-1343).
