CVE-2018-12178 [CRITICAL] CWE-125 edk2: improper DNS packet size check
edk2: improper DNS packet size check
Buffer overflow in network stack for EDK II may allow unprivileged user to potentially enable escalation of privilege and/or denial of service via network.
A missing check leads to an out-of-bounds read and write flaw in NetworkPkg/DnsDxe as shipped in edk2, when it parses DNS responses. A remote attacker who controls the DNS server used by the vulnerable firmware may use this flaw to make the system crash.
Statement: This issue did not affect the versions of OVMF as shipped with Red Hat Enterprise Linux 7 as they were not compiled with HTTP_BOOT_ENABLE set, thus they do not contain the vulnerable code.
Package: OVMF (Red Hat Enterprise Linux 7) - Not affected
Package: edk2 (Red Hat Enterprise Linux 8) - Not affected

CVE-2018-12178 [CRITICAL] CVE-2018-12178 edk2: improper DNS packet size check
CVE-2018-12178 edk2: improper DNS packet size check
A flaw was found in edk2. The DNS driver only checks the received packet size against the minimum DNS header size in DnsOnPacketReceived(), later it accesses the QueryName and QuerySection beyond the header scope, which might cause the pointer within DNS driver points to an invalid entry or modifies the memory content beyond the header scope.
