NETWORK Attack complexity
LOW Privileges required
NONE Confidentiality impact
NONE Integrity impact
HIGH Availability impact
HIGH Summary
The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets.

(CVE-2011-3188) Impact Attackers may be able to cause denial-of-service (DoS) or hijack network sessions by predicting sequence number values and sending crafted packets. This issue affects control-plane traffic generated by the Linux kernel, and does not affect data-plane traffic.Outbound connections initiated from the BIG-IP system by administrative applications such as BIG-IP health monitors, SNMP, SMTP, SSH, network time protocol (NTP), and so on, are processed by the Linux operating system, and may be exploited by this vulnerability. For more information, refer to K13284: Overview of management interface routing (11.x and later). Note : Vulnerability scanners searching for this vulnerability will sometimes return false positives, as they depend on a low entropy value in certain sequence numbers for this vulnerability. Identifying a low entropy value in these tests may be inherently prone to false positives. For more information on vulnerability scanners, refer toK31046057: CVE security vulnerability scanners may report false positive results. last seen 2020-06-01 modified 2020-06-02 plugin id 78170 published 2014-10-10 reporter This script is Copyright (C) 2014-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/78170 title F5 Networks BIG-IP : Linux kernel TCP ISN vulnerability (K15301) NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2011-1465.NASL description From Red Hat Security Advisory 2011:1465 : Updated kernel packages that fix multiple security issues and various bugs are now available for Red Hat Enterprise Linux 6.

Race condition in the ecryptfs_mount function in fs/ecryptfs/main.c in the eCryptfs subsystem in the Linux kernel before 3.1 allows local users to bypass intended file permissions via a mount.ecryptfs_private mount with a mismatched uid. The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets. Integer signedness error in the CIFSFindNext function in fs/cifs/cifssmb.c in the Linux kernel before 3.1 allows remote CIFS servers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a large length value in a response to a read request for a directory.

(BZ#768413) * IBM x3650m3 systems were not able to boot the MRG Realtime kernel because they require a pmcraid driver that was not available. The pmcraid driver is included in this update. (BZ#753992) Users should upgrade to these updated packages, which correct these issues. The system must be rebooted for this update to take effect. last seen 2020-06-01 modified 2020-06-02 plugin id 76635 published 2014-07-22 reporter This script is Copyright (C) 2014-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/76635 title RHEL 6 : MRG (RHSA-2012:0010) NASL family Amazon Linux Local Security Checks NASL id ALA_ALAS-2011-26.NASL description IPv6 fragment identification value generation could allow a remote attacker to disrupt a target system last seen 2020-06-01 modified 2020-06-02 plugin id 69585 published 2013-09-04 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/69585 title Amazon Linux AMI : kernel (ALAS-2011-26) NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-1253-1.NASL description Ryan Sweat discovered that the kernel incorrectly handled certain VLAN packets. On some systems, a remote attacker could send specially crafted traffic to crash the system, leading to a denial of service. (CVE-2011-1576) Vasiliy Kulikov and Dan Rosenberg discovered that ecryptfs did not correctly check the origin of mount points. A local attacker could exploit this to trick the system into unmounting arbitrary mount points, leading to a denial of service. (CVE-2011-1833) Vasiliy Kulikov discovered that taskstats did not enforce access restrictions. A local attacker could exploit this to read certain information, leading to a loss of privacy. (CVE-2011-2494) Vasiliy Kulikov discovered that /proc/PID/io did not enforce access restrictions. A local attacker could exploit this to read certain information, leading to a loss of privacy. (CVE-2011-2495) Dan Rosenberg discovered that the Bluetooth stack incorrectly handled certain L2CAP requests. If a system was using Bluetooth, a remote attacker could send specially crafted traffic to crash the system or gain root privileges. (CVE-2011-2497) It was discovered that the EXT4 filesystem contained multiple off-by-one flaws. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-2695) Fernando Gont discovered that the IPv6 stack used predictable fragment identification numbers. A remote attacker could exploit this to exhaust network resources, leading to a denial of service. (CVE-2011-2699) Christian Ohm discovered that the perf command looks for configuration files in the current directory. If a privileged user were tricked into running perf in a directory containing a malicious configuration file, an attacker could run arbitrary commands and possibly gain privileges. (CVE-2011-2905) Time Warns discovered that long symlinks were incorrectly handled on Be filesystems. A local attacker could exploit this with a malformed Be filesystem and crash the system, leading to a denial of service. (CVE-2011-2928) Dan Kaminsky discovered that the kernel incorrectly handled random sequence number generation. An attacker could use this flaw to possibly predict sequence numbers and inject packets. (CVE-2011-3188) Darren Lavender discovered that the CIFS client incorrectly handled certain large values. A remote attacker with a malicious server could exploit this to crash the system or possibly execute arbitrary code as the root user. (CVE-2011-3191) Han-Wen Nienhuys reported a flaw in the FUSE kernel module. A local user who can mount a FUSE file system could cause a denial of service.

(CVE-2011-3188) Yogesh Sharma discovered that CIFS did not correctly handle UNCs that had no prefixpaths. A local attacker with access to a CIFS partition could exploit this to crash the system, leading to a denial of service. (CVE-2011-3363).

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 56642 published 2011-10-26 reporter Ubuntu Security Notice (C) 2011-2019 Canonical, Inc. / NASL script (C) 2011-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/56642 title Ubuntu 10.10 : linux vulnerabilities (USN-1243-1) NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2011-1419.NASL description Updated kernel packages that fix two security issues and four bugs are now available for Red Hat Enterprise Linux 5.6 Extended Update Support. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * The way IPv4 and IPv6 protocol sequence numbers and fragment IDs were generated could allow a man-in-the-middle attacker to inject packets and possibly hijack connections. Protocol sequence numbers and fragment IDs are now more random.
