Astra Linux – vulnerability in Thunderbird

The olmsessiondescribe function in Matrix’s libolm prior to version 3.2.7 is vulnerable to a buffer overflow. An Olm session object represents a cryptographic channel between two parties; thus, its state can be partially controlled by the remote party. Attackers can craft a sequence of messages t...
