Description Tomas Hoger 2007-08-10 11:38:31 UTC

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.

"Red Hat does not consider a user assisted client crash such as this to be a
security flaw."
