Vulnerability from variot
Jonathan Looney discovered that the TCP retransmission queue implementation in tcp_fragment in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. 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 f070ef2ac66716357066b683fb0baf55f8191a2e. This vulnerability stems from improper management of system resources (such as memory, disk space, files, etc.) by network systems or products. 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. 7.3) - noarch, x86_64

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)

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. 8) - aarch64, noarch, ppc64le, s390x, x86_64

Summary:\n\nAn update for kernel is now available for Red Hat Enterprise Linux 7. \n\nRed Hat Product Security has rated this update as having a security impact\nof Important. A Common Vulnerability Scoring System (CVSS) base score,\nwhich gives a detailed severity rating, is available for each vulnerability\nfrom the CVE link(s) in the References section. \n\n2. Relevant releases/architectures:\n\nRed Hat Enterprise Linux Client (v. 7) - noarch, x86_64\nRed Hat Enterprise Linux Client Optional (v. 7) - x86_64\nRed Hat Enterprise Linux ComputeNode (v. 7) - noarch, x86_64\nRed Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64\nRed Hat Enterprise Linux Server (v. 7) - noarch, ppc64, ppc64le, s390x, x86_64\nRed Hat Enterprise Linux Server Optional (v. 7) - ppc64, ppc64le, x86_64\nRed Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64\nRed Hat Enterprise Linux Workstation Optional (v. 7) - x86_64\n\n3. While processing SACK segments, the Linux kernel\u0027s socket buffer\n(SKB) data structure becomes fragmented. Each fragment is about TCP maximum\nsegment size (MSS) bytes. To efficiently process SACK blocks, the Linux\nkernel merges multiple fragmented SKBs into one, potentially overflowing\nthe variable holding the number of segments. A remote attacker could use\nthis flaw to crash the Linux kernel by sending a crafted sequence of SACK\nsegments on a TCP connection with small value of TCP MSS, resulting in a\ndenial of service (DoS). (CVE-2019-11477)\n\n* Kernel: tcp: excessive resource consumption while processing SACK blocks\nallows remote denial of service (CVE-2019-11478)\n\n* Kernel: tcp: excessive resource consumption for TCP connections with low\nMSS allows remote denial of service (CVE-2019-11479)\n\nFor more details about the security issue(s), including the impact, a CVSS\nscore, acknowledgments, and other related information, refer to the CVE\npage(s) listed in the References section. \n\n4. Solution:\n\nFor details on how to apply this update, which includes the changes\ndescribed in this advisory, refer to:\n\nhttps://access.redhat.com/articles/11258\n\nThe system must be rebooted for this update to take effect. \n\n5.
