FreeBSD : polarssl -- Remote attack using crafted certificates (a5856eba-a015-11e4-a680-1c6f65c3c4ff)

high Nessus Plugin ID 80840

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

PolarSSL team reports :

During the parsing of a ASN.1 sequence, a pointer in the linked list of asn1_sequence is not initialized by asn1_get_sequence_of(). In case an error occurs during parsing of the list, a situation is created where the uninitialized pointer is passed to polarssl_free().

This sequence can be triggered when a PolarSSL entity is parsing a certificate. So practically this means clients when receiving a certificate from the server or servers in case they are actively asking for a client certificate.

Solution

Update the affected packages.
