FreeBSD : gnu-radius -- SNMP-related denial-of-service (e6f0edd8-0b40-11d9-8a8a-000c41e2cdad)

medium Nessus Plugin ID 19150

Synopsis

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

Description

An iDEFENSE security advisory reports :

Remote exploitation of an input validation error in version 1.2 of GNU radiusd could allow a denial of service.

The vulnerability specifically exists within the asn_decode_string() function defined in snmplib/asn1.c. When a very large unsigned number is supplied, it is possible that an integer overflow will occur in the bounds-checking code. The daemon will then attempt to reference unallocated memory, resulting in an access violation that causes the process to terminate.

Solution

Update the affected package.
