Background
==========
CAPI4Hylafax makes it possible to send and receive faxes via CAPI and AVM Fritz!Cards.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 capi4hylafax < 01.03.00.99.300.3-r1 >= 01.03.00.99.300.3-r1
Description
===========
Lionel Elie Mamane discovered an error in c2faxrecv, which doesn't properly sanitize TSI strings when handling incoming calls.
Impact

Workaround

There is no known workaround at this time.
Resolution
==========
All CAPI4Hylafax users should upgrade to the latest version:
