Description Tomas Hoger 2007-08-10 11:55:45 UTC

Multiple stack-based buffer overflows in fsplib.c in fsplib before 0.9 might
allow remote attackers to execute arbitrary code via (1) a long filename that is
not properly handled by the fsp_readdir_native function when MAXNAMLEN is
greater than 255, or (2) a long d_name directory (dirent) field in the
fsp_readdir function.

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

fsplib upstream patches:

Comment 2 Tomas Hoger 2007-08-10 12:23:54 UTC

Both issue only affect platforms with MAXNAMLEN > 255, i.e. not Linux.  Setting
low priority and severity.

Comment 3 Mark J. Cox 2007-08-10 13:01:26 UTC

Not vulnerable.  fsplib is part of gftp in Red Hat Enterprise Linux 5, but this
issue does not affect Linux.
