    CVE ID         : CVE-2018-5390 CVE-2018-13405
    
    Several vulnerabilities have been discovered in the Linux kernel that
    may lead to a privilege escalation or denial of service.
    
    CVE-2018-5390
    
        Juha-Matti Tilli discovered that a remote attacker can trigger the
        worst case code paths for TCP stream reassembly with low rates of
        specially crafted packets leading to remote denial of service.
    
    CVE-2018-13405
    
        Jann Horn discovered that the inode_init_owner function in
        fs/inode.c in the Linux kernel allows local users to create files
        with an unintended group ownership allowing attackers to escalate
        privileges by making a plain file executable and SGID.
    
    For the stable distribution (stretch), these problems have been fixed in
    version 4.9.110-3+deb9u1. This update includes fixes for several
    regressions in the latest point release.
    
    We recommend that you upgrade your linux packages.
