FreeBSD : Botan BER Decoder vulnerabilities (2004616d-f66c-11e5-b94c-001999f8d30b)

high Nessus Plugin ID 90286

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

The botan developers reports :

Excess memory allocation in BER decoder - The BER decoder would allocate a fairly arbitrary amount of memory in a length field, even if there was no chance the read request would succeed. This might cause the process to run out of memory or invoke the OOM killer.

Crash in BER decoder - The BER decoder would crash due to reading from offset 0 of an empty vector if it encountered a BIT STRING which did not contain any data at all. This can be used to easily crash applications reading untrusted ASN.1 data, but does not seem exploitable for code execution.

Solution

Update the affected package.
