Description:
strongswan - IPSec utilities for strongSwan
Changes:
strongswan (4.2.4-5+lenny2) stable-security; urgency=high
.
Applied ASN.1 and other security fixes from upstream:
* Fixes a Denial-of-Service vulnerability where receiving a malformed
IKE_AUTH request with either a missing TSi or TSr traffic selector
payload causes a crash of the IKEv2 charon while dereferencing a NULL
pointer because the NULL pointer checks of TSi and TSr before destruction
were erroneously swapped.
* The RDN parser vulnerability discovered by Orange Labs research team
was not completely fixed in version 4.2.16. Some more modifications had
to be applied to the asn1_length() function.
* Applying their fuzzing tool, the Orange Labs vulnerability research team
found a Denial-of-Service vulnerability in the parsing of ASN.1 Relative
Distinguished Names (RDNs). Malformed X.509 certificate RDNs can cause
the pluto and charon IKE daemons to crash and restart.
* Applying their fuzzing tool, the Orange Labs vulnerability research team
found a Denial-of-Service vulnerability in the parsing of ASN.1 UTCTIME
and GENERALIZEDTIME strings. Malformed X.509 certificate time strings can
cause the pluto and charon IKE daemons to crash and restart.
* Fixes a Denial-of-Service vulnerability where receiving a malformed
IKE_SA_INIT request leaves an incomplete state which causes a crash of
the IKEv2 charon while dereferencing a NULL pointer if a subsequent
CREATE_CHILD_SA is received.
