From 2bfbf7a18e48127efd9b3d2d0976db6dffc476ff Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Tue, 3 Sep 2013 16:52:06 +0100 Subject: [PATCH] Fix crash in remoteDispatchDomainMemoryStats (CVE-2013-4296) The 'stats' variable was not initialized to NULL, so if some early validation of the RPC call fails, it is possible to jump to the 'cleanup' label and VIR_FREE an uninitialized pointer. This is a security flaw, since the API can be called from a readonly connection which can trigger the validation checks. This was introduced in release v0.9.1 onwards by commit 158ba8730e44b7dd07a21ab90499996c5dec080a Author: Daniel P. Berrange Date: Wed Apr 13 16:21:35 2011 +0100 Merge all returns paths from dispatcher into single path Signed-off-by: Daniel P.
