Description Mark J. Cox 2003-11-25 12:48:06 UTC
A remote DoS in FreeRadius was reported on Bugtraq Nov20 (up to
version 0.9.2):

A RADIUS attribute which has a 'tag' (RFC 2868), and is of type
'string', and which is 2-3 octets long, may cause the server to call
'memcpy' with a length argument of '-1'.

CVE name requested

Affects: 3AS 3ES

Comment 1 Mark J. Cox 2003-11-27 09:48:43 UTC

rad_decode in FreeRADIUS 0.9.2 and earlier allows remote attackers to
cause a denial of service (crash) via a short RADIUS string attribute
with a tag, which causes memcpy to be called with a -1 length
argument, as demonstrated using the Tunnel-Password attribute.


Stack-based buffer overflow in SMB_Logon_Server of the rlm_smb
experimental module for FreeRADIUS 0.9.3 and earlier allows remote
attackers to execute arbitrary code via a long User-Password

(note the latter is only in an experimental non-default module)
