Scientific Linux Security Update : shim on SL7.x x86_64

High Nessus Plugin ID 81294


The remote Scientific Linux host is missing one or more security updates.


A heap-based buffer overflow flaw was found the way shim parsed certain IPv6 addresses. If IPv6 network booting was enabled, a malicious server could supply a crafted IPv6 address that would cause shim to crash or, potentially, execute arbitrary code. (CVE-2014-3676)

An out-of-bounds memory write flaw was found in the way shim processed certain Machine Owner Keys (MOKs). A local attacker could potentially use this flaw to execute arbitrary code on the system. (CVE-2014-3677)

An out-of-bounds memory read flaw was found in the way shim parsed certain IPv6 packets. A specially crafted DHCPv6 packet could possibly cause shim to crash, preventing the system from booting if IPv6 booting was enabled. (CVE-2014-3675)

The system must be rebooted for this update to take effect.


Update the affected packages.
