CVE-2019-11477


TITLE

Linux kernel Input validation error vulnerability

Trust: 0.6

sources: CNNVD: CNNVD-201906-681

DESCRIPTION

Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). 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 commit 3b4929f65b0d8249f19a50245cd88ed1a2f78cff. A successful exploit could cause the targeted system to crash, resulting in a DoS condition. Proof-of-concept (PoC) code that demonstrates an exploit of this vulnerability is publicly available. Kernel.org has confirmed the vulnerability and released software updates. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2019:1484-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2019:1484 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 7.3 Advanced Update Support, Red Hat Enterprise Linux 7.3 Telco Extended Update Support, and Red Hat Enterprise Linux 7.3 Update Services for SAP Solutions. 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 Server AUS (v. 7.3) - noarch, x86_64 Red Hat Enterprise Linux Server E4S (v. 7.3) - noarch, ppc64le, x86_64 Red Hat Enterprise Linux Server Optional AUS (v. 7.3) - x86_64 Red Hat Enterprise Linux Server Optional E4S (v. 7.3) - ppc64le, x86_64 Red Hat Enterprise Linux Server Optional TUS (v. 7.3) - x86_64 Red Hat Enterprise Linux Server TUS (v. 7.3) - noarch, x86_64 3. 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. 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. 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.
