The issue is related to errors in cryptographic signature verification, allowing a remote attacker to modify the content of an ODF document. It is possible for an attacker to manipulate documents to appear to be signed by a trusted source.

The issue is related to errors in cryptographic signature verification, allowing an attacker to manipulate signed documents and macros to appear as if they come from a trusted source.

The issue is related to errors in checking signed documents, which can be exploited by a remote attacker to compromise the integrity of information. It is possible for an attacker to manipulate the timestamp of signed documents.
