MGASA-2017-0026 - Updated pcsc-lite packages fix security vulnerability

Publication date: 27 Jan 2017
URL: http://advisories.mageia.org/MGASA-2017-0026.html
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)
