The (1) remoteglob function in sftp-glob.c and the (2) processput function in sftp.c in OpenSSH 5.8 and earlier, as used in FreeBSD 7.3 and 8.1, NetBSD 5.0.2, OpenBSD 4.7, and other products, allow remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in SSHFXPSTAT requests to an sftp daemon, a different vulnerability than CVE-2010-2632.
