Debian Security Advisory DSA-4266-1 [email protected]

Package : linux
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.
