Detail
Problem Description: An update for kernel is now available for Red Hat Enterprise Linux 6.7 Extended Update Support. 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 HPC Node EUS (v. 6.7) - noarch, x86_64 Red Hat Enterprise Linux HPC Node Optional EUS (v. 6.7) - x86_64 Red Hat Enterprise Linux Server EUS (v. 6.7) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 6.7) - i386, ppc64, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * It was found that the RFC 5961 challenge ACK rate limiting as implemented in the Linux kernel's networking subsystem allowed an off-path attacker to leak certain information about a given connection by creating congestion on the global challenge ACK rate limit counter and then measuring the changes by probing packets. An off-path attacker could use this flaw to either terminate TCP connection and/or inject payload into non-secured TCP connection between two endpoints on the network. (CVE-2016-5696, Important) Red Hat would like to thank Yue Cao (Cyber Security Group of the CS department of University of California in Riverside) for reporting this issue. Bug Fix(es): * When an interrupt request occurred and the new API was scheduled on a different CPU, the enic driver previously generated a warning message. This behavior was caused by a race condition between the vnic_intr_unmask() function and the enic_poll_unlock_napi() function. This update fixes the napi_poll() function to unlock before unmasking the interrupt. As a result, the warning message no longer occurs in the described situation. (BZ#1351192) 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. Bugs fixed (https://bugzilla.redhat.com/): 1354708 - CVE-2016-5696 kernel: challenge ACK counter information disclosure. |
