NASL family Debian Local Security Checks NASL id DEBIAN_DSA-1928.NASL description Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, sensitive memory leak or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2009-2846 Michael Buesch noticed a typing issue in the eisa-eeprom driver for the hppa architecture. Local users could exploit this issue to gain access to restricted memory. - CVE-2009-2847 Ulrich Drepper noticed an issue in the do_sigalstack routine on 64-bit systems. This issue allows local users to gain access to potentially sensitive memory on the kernel stack. - CVE-2009-2848 Eric Dumazet discovered an issue in the execve path, where the clear_child_tid variable was not being properly cleared. Local users could exploit this issue to cause a denial of service (memory corruption). - CVE-2009-2849 Neil Brown discovered an issue in the sysfs interface to md devices. When md arrays are not active, local users can exploit this vulnerability to cause a denial of service (oops). - CVE-2009-2903 Mark Smith discovered a memory leak in the appletalk implementation.

A local user can cause a denial of service (kernel oops) by causing a dentry value to go negative. - CVE-2009-2909 Arjan van de Ven discovered an issue in the AX.25 protocol implementation. A specially crafted call to setsockopt() can result in a denial of service (kernel oops). - CVE-2009-2910 Jan Beulich discovered the existence of a sensitive kernel memory leak. Systems running the 'amd64' kernel do not properly sanitize registers for 32-bit processes. - CVE-2009-3001 Jiri Slaby fixed a sensitive memory leak issue in the ANSI/IEEE 802.2 LLC implementation. This is not exploitable in the Debian lenny kernel as root privileges are required to exploit this issue. - CVE-2009-3002 Eric Dumazet fixed several sensitive memory leaks in the IrDA, X.25 PLP (Rose), NET/ROM, Acorn Econet/AUN, and Controller Area Network (CAN) implementations. Local users can exploit these issues to gain access to kernel memory. - CVE-2009-3228 Eric Dumazet reported an instance of uninitialized kernel memory in the network packet scheduler. Local users may be able to exploit this issue to read the contents of sensitive kernel memory. - CVE-2009-3238 Linus Torvalds provided a change to the get_random_int() function to increase its randomness. - CVE-2009-3286 Eric Paris discovered an issue with the NFSv4 server implementation. When an O_EXCL create fails, files may be left with corrupted permissions, possibly granting unintentional privileges to other local users. - CVE-2009-3547 Earl Chew discovered a NULL pointer dereference issue in the pipe_rdwr_open function which can be used by local users to gain elevated privileges. - CVE-2009-3612 Jiri Pirko discovered a typo in the initialization of a structure in the netlink subsystem that may allow local users to gain access to sensitive kernel memory. - CVE-2009-3613 Alistair Strachan reported an issue in the r8169 driver. Remote users can cause a denial of service (IOMMU space exhaustion and system crash) by transmitting a large amount of jumbo frames. - CVE-2009-3620 Ben Hutchings discovered an issue in the DRM manager for ATI Rage 128 graphics adapters. Local users may be able to exploit this vulnerability to cause a denial of service (NULL pointer dereference). - CVE-2009-3621 Tomoki Sekiyama discovered a deadlock condition in the UNIX domain socket implementation. Local users can exploit this vulnerability to cause a denial of service (system hang)." ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-2846" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-2847" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-2848" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-2849" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-2903" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-2908" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-2909" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-2910" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-3001" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-3002" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-3228" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-3238" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-3286" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-3547" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-3612" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-3613" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-3620" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2009-3621" ); script_set_attribute( attribute:"see_also", value:"https://www.debian.org/security/2009/dsa-1928" ); script_set_attribute( attribute:"solution", value: "Upgrade the linux-2.6.24 packages.

NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2009-1438.NASL description From Red Hat Security Advisory 2009:1438 : Updated kernel packages that fix several security issues and several bugs are now available for Red Hat Enterprise Linux 4. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2009-1895, Important) * it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important) * Solar Designer reported a missing capability check in the z90crypt driver in the Linux kernel. This missing check could allow a local user with an effective user ID (euid) of 0 to bypass intended capability restrictions. (CVE-2009-1883, Moderate) * a flaw was found in the way the do_sigaltstack() function in the Linux kernel copies the stack_t structure to user-space. On 64-bit machines, this flaw could lead to a four-byte information leak. (CVE-2009-2847, Moderate) This update also fixes the following bugs : * the gcc flag last seen 2020-06-01 modified 2020-06-02 plugin id 67925 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/67925 title Oracle Linux 4 : kernel (ELSA-2009-1438) 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-2009:1438 and # Oracle Linux Security Advisory ELSA-2009-1438 respectively. # include("compat.inc"); if (description) { script_id(67925); script_version("1.17"); script_cvs_date("Date: 2019/10/25 13:36:08"); script_cve_id("CVE-2009-1883", "CVE-2009-1895", "CVE-2009-2847", "CVE-2009-2848", "CVE-2009-3238"); script_bugtraq_id(35647, 35930); script_xref(name:"RHSA", value:"2009:1438"); script_name(english:"Oracle Linux 4 : kernel (ELSA-2009-1438)"); script_summary(english:"Checks rpm output for the updated packages"); script_set_attribute( attribute:"synopsis", value:"The remote Oracle Linux host is missing one or more security updates." ); script_set_attribute( attribute:"description", value: "From Red Hat Security Advisory 2009:1438 : Updated kernel packages that fix several security issues and several bugs are now available for Red Hat Enterprise Linux 4.

On 64-bit machines, this flaw could lead to a four-byte information leak. (CVE-2009-2847, Moderate) This update also fixes the following bugs : * the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers. Keeping these checks is a safety measure. (BZ#517964) * the Emulex LPFC driver has been updated to version 8.0.16.47, which fixes a memory leak that caused memory allocation failures and system hangs. (BZ#513192) * an error in the MPT Fusion driver makefile caused CSMI ioctls to not work with Serial Attached SCSI devices. (BZ#516184) * this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer deference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility. (BZ#517904) * time-outs resulted in I/O errors being logged to '/var/log/messages' when running 'mt erase' on tape drives using certain LSI MegaRAID SAS adapters, preventing the command from completing. The megaraid_sas driver's timeout value is now set to the OS layer value. (BZ#517965) * a locking issue caused the qla2xxx ioctl module to hang after encountering errors. This locking issue has been corrected. This ioctl module is used by the QLogic SAN management tools, such as SANsurfer and scli. (BZ#519428) * when a RAID 1 array that uses the mptscsi driver and the LSI 1030 controller became degraded, the whole array was detected as being offline, which could cause kernel panics at boot or data loss. (BZ#517295) * on 32-bit architectures, if a file was held open and frequently written for more than 25 days, it was possible that the kernel would stop flushing those writes to storage. (BZ#515255) * a memory allocation bug in ib_mthca prevented the driver from loading if it was loaded with large values for the 'num_mpt=' and 'num_mtt=' options. (BZ#518707) * with this update, get_random_int() is more random and no longer uses a common seed value, reducing the possibility of predicting the values returned. (BZ#519692) * a bug in __ptrace_unlink() caused it to create deadlocked and unkillable processes. (BZ#519446) * previously, multiple threads using the fcntl() F_SETLK command to synchronize file access caused a deadlock in posix_locks_deadlock(). This could cause a system hang.

NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2009-1466.NASL description Updated kernel packages that fix two security issues and several bugs are now available for Red Hat Enterprise Linux 5.3 Extended Update Support. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update includes backported fixes for two security issues. These issues only affected users of Red Hat Enterprise Linux 5.3 Extended Update Support as they have already been addressed for users of Red Hat Enterprise Linux 5 in the 5.4 update, RHSA-2009:1243. In accordance with the support policy, future security updates to Red Hat Enterprise Linux 5.3 Extended Update Support will only include issues of critical security impact. This update fixes the following security issues : * it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important) * a flaw was found in the way the do_sigaltstack() function in the Linux kernel copies the stack_t structure to user-space. On 64-bit machines, this flaw could lead to a four-byte information leak. (CVE-2009-2847, Moderate) This update also fixes the following bugs : * a regression was found in the SCSI retry logic: SCSI mode select was not retried when retryable errors were encountered. In Device-Mapper Multipath environments, this could cause paths to fail, or possibly prevent successful failover.

(CVE-2009-2849) Mark Smith discovered that the AppleTalk stack did not correctly manage memory. A remote attacker could send specially crafted traffic to cause the system to consume all available memory, leading to a denial of service. (CVE-2009-2903) Loic Minier discovered that eCryptfs did not correctly handle writing to certain deleted files. A local attacker could exploit this to gain root privileges or crash the system, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-2908) It was discovered that the LLC, AppleTalk, IR, EConet, Netrom, and ROSE network stacks did not correctly initialize their data structures. A local attacker could make specially crafted calls to read kernel memory, leading to a loss of privacy. (CVE-2009-3001, CVE-2009-3002) It was discovered that the randomization used for Address Space Layout Randomization was predictable within a small window of time. A local attacker could exploit this to leverage further attacks that require knowledge of userspace memory layouts. (CVE-2009-3238) Eric Paris discovered that NFSv4 did not correctly handle file creation failures. An attacker with write access to an NFSv4 share could exploit this to create files with arbitrary mode bits, leading to privilege escalation or a loss of privacy. (CVE-2009-3286) Bob Tracy discovered that the SCSI generic driver did not correctly use the right index for array access. A local attacker with write access to a CDR could exploit this to crash the system, leading to a denial of service. Only Ubuntu 9.04 was affected. (CVE-2009-3288) Jan Kiszka discovered that KVM did not correctly validate certain hypercalls. A local unprivileged attacker in a virtual guest could exploit this to crash the guest kernel, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-3290).

The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2009-2698 Herbert Xu discovered an issue in the way UDP tracks corking status that could allow local users to cause a denial of service (system crash). Tavis Ormandy and Julien Tinnes discovered that this issue could also be used by local users to gain elevated privileges. - CVE-2009-2846 Michael Buesch noticed a typing issue in the eisa-eeprom driver for the hppa architecture. Local users could exploit this issue to gain access to restricted memory. - CVE-2009-2847 Ulrich Drepper noticed an issue in the do_sigalstack routine on 64-bit systems. This issue allows local users to gain access to potentially sensitive memory on the kernel stack. - CVE-2009-2848 Eric Dumazet discovered an issue in the execve path, where the clear_child_tid variable was not being properly cleared. Local users could exploit this issue to cause a denial of service (memory corruption). - CVE-2009-2849 Neil Brown discovered an issue in the sysfs interface to md devices. When md arrays are not active, local users can exploit this vulnerability to cause a denial of service (oops). last seen 2020-06-01 modified 2020-06-02 plugin id 44737 published 2010-02-24 reporter This script is Copyright (C) 2010-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/44737 title Debian DSA-1872-1 : linux-2.6 - denial of service/privilege escalation/information leak
