Description Tomas Hoger 2007-08-10 07:38:31 EDT 
Off-by-one error in the fsp_readdir_r function in fsplib.c in fsplib before 0.9
allows remote attackers to cause a denial of service via a directory entry whose
length is exactly MAXNAMLEN, which prevents a terminating null byte from being
added.

gFTP contains local copy of fsplib source code to support FSP protocol.

Comment 2 Mark J. Cox 2007-08-10 08:58:18 EDT 
"Red Hat does not consider a user assisted client crash such as this to be a
security flaw."
