CVE-2019-11479

TITLE

Brocade Fabric OS Resource Management Error Vulnerability

DESCRIPTION

Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commits 967c05aee439e6e5d7d805e195b3a20ef5c433d6 and 5f3e2bf008c2221478101ee72f5cb4654b9fc363. This vulnerability stems from improper management of system resources (such as memory, disk space, files, etc.) by network systems or products. 7.3) - noarch, x86_64 3. Bug Fix(es): * THP: Race between MADV_DONTNEED and NUMA hinting node migration code (BZ#1698104) * [RHEL7] md_clear flag missing from /proc/cpuinfo on late microcode update (BZ#1712990) * [RHEL7] MDS mitigations are not enabled after double microcode update (BZ#1712995) * WARNING: CPU: 0 PID: 0 at kernel/jump_label.c:90 __static_key_slow_dec+0xa6/0xb0 (BZ#1713001) 4. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security update Advisory ID: RHSA-2019:1481-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2019:1481 Issue date: 2019-06-17 CVE Names: CVE-2019-11477 CVE-2019-11478 CVE-2019-11479 ==================================================================== 1. Summary: An update for kernel is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - noarch, x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, ppc64le, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * An integer overflow flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment (SACK) segments. While processing SACK segments, the Linux kernel's socket buffer (SKB) data structure becomes fragmented. Each fragment is about TCP maximum segment size (MSS) bytes. To efficiently process SACK blocks, the Linux kernel merges multiple fragmented SKBs into one, potentially overflowing the variable holding the number of segments. A remote attacker could use this flaw to crash the Linux kernel by sending a crafted sequence of SACK segments on a TCP connection with small value of TCP MSS, resulting in a denial of service (DoS). (CVE-2019-11477) * Kernel: tcp: excessive resource consumption while processing SACK blocks allows remote denial of service (CVE-2019-11478) * Kernel: tcp: excessive resource consumption for TCP connections with low MSS allows remote denial of service (CVE-2019-11479) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5.

Description: The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. CVE-2019-3846, CVE-2019-10126 huangwen reported multiple buffer overflows in the Marvell wifi (mwifiex) driver, which a local user could use to cause denial of service or the execution of arbitrary code. CVE-2019-5489 Daniel Gruss, Erik Kraft, Trishita Tiwari, Michael Schwarz, Ari Trachtenberg, Jason Hennessey, Alex Ionescu, and Anders Fogh discovered that local users could use the mincore() system call to obtain sensitive information from other processes that access the same memory-mapped file. CVE-2019-11477 Jonathan Looney reported that a specially crafted sequence of TCP selective acknowledgements (SACKs) allows a remotely triggerable kernel panic. CVE-2019-11478 Jonathan Looney reported that a specially crafted sequence of TCP selective acknowledgements (SACKs) will fragment the TCP retransmission queue, allowing an attacker to cause excessive resource usage. CVE-2019-11479 Jonathan Looney reported that an attacker could force the Linux kernel to segment its responses into multiple TCP segments, each of which contains only 8 bytes of data, drastically increasing the bandwidth required to deliver the same amount of data. This update introduces a new sysctl value to control the minimal MSS (net.ipv4.tcp_min_snd_mss), which by default uses the formerly hard- coded value of 48. We recommend raising this to 536 unless you know that your network requires a lower value. CVE-2019-11486 Jann Horn of Google reported numerous race conditions in the Siemens R3964 line discipline. This module has therefore been disabled. CVE-2019-11599 Jann Horn of Google reported a race condition in the core dump implementation which could lead to a use-after-free. CVE-2019-11815 It was discovered that a use-after-free in the Reliable Datagram Sockets protocol could result in denial of service and potentially privilege escalation. This protocol module (rds) is not auto- loaded on Debian systems, so this issue only affects systems where it is explicitly loaded. CVE-2019-11833 It was discovered that the ext4 filesystem implementation writes uninitialised data from kernel memory to new extent blocks. A local user able to write to an ext4 filesystem and then read the filesystem image, for example using a removable drive, might be able to use this to obtain sensitive information. CVE-2019-11884 It was discovered that the Bluetooth HIDP implementation did not ensure that new connection names were null-terminated. A local user with CAP_NET_ADMIN capability might be able to use this to obtain sensitive information from the kernel stack.
