Title: SSH Communications Security's Secure Shell Server: SFTP privilege escalation (GLSA 200703-13)
Date: March 14, 2007
The SSH Secure Shell Server SFTP function is vulnerable to privilege escalation.
The SSH Secure Shell Server from SSH Communications Security (www.ssh.com) is a commercial SSH implementation available free for non-commercial use.
Vulnerable: < 4.3.7
Architectures: All supported architectures
The SSH Secure Shell Server contains a format string vulnerability in the SFTP code that handles file transfers (scp2 and sftp2). In some situations, this code passes the accessed filename to the system log. During this operation, an unspecified error could allow uncontrolled stack access.
An authenticated system user may be able to exploit this vulnerability to bypass command restrictions, or run commands as another user.
There is no known workaround at this time.
This package is currently masked, there is no upgrade path for the 3.2.x version, and a license must be purchased in order to update to a non-vulnerable version. Because of this, we recommend unmerging this package:
|# emerge --ask --verbose --unmerge net-misc/ssh |
