Insufficient bounding of "REP MOVS" to MMIO emulated inside the hypervisor

ISSUE DESCRIPTION Acceleration support for the "REP MOVS" instruction, when the first iteration accesses memory mapped I/O emulated internally in the hypervisor, incorrectly assumes that the whole range accessed is handled by the same hypervisor sub-component. IMPACT A buggy or malicious HVM gues...

F5 Networks BIG-IP : GnuTLS vulnerability (SOL15637)

The gnutlsciphertext2compressed function in lib/gnutlscipher.c in GnuTLS 2.12.23 allows remote attackers to cause a denial of service buffer over-read and crash via a crafted padding length. NOTE: this might be due to an incorrect fix for CVE-2013-0169. C Tenable Network Security, Inc. The...
