gnu-radius -- SNMP-related denial-of-service

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.
