Publication date: 27 Jan 2017
Modification date: 27 Jan 2017
Type: security
Affected Mageia releases : 5
CVE: CVE-2016-10109

Description

Once MSGRemoveContext is invoked (via SCARD_RELEASE_CONTEXT), cardsList
is freed. A repeated invocation of SCARD_RELEASE_CONTEXT (with an empty
context handle) results in a use-after-free followed by a double-free.

After MSGRemoveContext, invocation of SCardEstablishContext enable
further use-after-free of cardsList in MSGCheckHandleAssociation,
MSGRemoveContext, MSGAddHandle, MSGRemoveHandle.

To avoid this problem, destroy the list only when the client connection
is terminated. (CVE-2016-10109)
