GLSA-200703-13 : SSH Communications Security's Secure Shell Server: SFTP privilege escalation

medium Nessus Plugin ID 24830

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200703-13 (SSH Communications Security's Secure Shell Server: SFTP privilege escalation)

 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.
 Impact :

 An authenticated system user may be able to exploit this vulnerability to bypass command restrictions, or run commands as another user.
 Workaround :

 There is no known workaround at this time.

Solution

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
