Sun(sm) Alert Notification
* Sun Alert ID: 102961
* Synopsis: Security Vulnerability in scp(1) May Allow Execution of
Unintended Commands
* Category: Security
* Product: Solaris 9 Operating System, Solaris 10 Operating System
* BugIDs: 6472377
* Avoidance: Patch, Workaround
* State: Resolved
* Date Released: 08-Jun-2007, 27-Jun-2007
* Date Closed: 27-Jun-2007
* Date Modified: 21-Jun-2007, 27-Jun-2007
1. Impact
Due to a security vulnerability in the way the scp(1) command executes
helper applications, certain additional unintended commands may be
executed at the same time. This may allow a local unprivileged user
(or a remote user in the case of shared filesystems) who is able to
create files on the system, to execute arbitrary commands with the
privileges of a local user, if those files are acted upon by the local
user using the scp(1) command.
This issue is also referenced in the following document:
CVE-2006-0225
at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0225
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 9 without patch 114356-12
* Solaris 10 without patch 123324-03
x86 Platform
* Solaris 9 without patch 114357-11
* Solaris 10 without patch 123325-03
Note: Solaris 8 does not include the scp(1) command and is therefore
not impacted by this issue.
3. Symptoms
There are no predictable symptoms that would indicate that this issue
has been exploited to execute arbitrary commands.
4. Relief/Workaround
This issue will only occur if the scp(1) command is executed on files
that have specially crafted filenames. Therefore, it may be possible
to work around this issue by avoiding the use of the scp(1) command on
untrusted filenames, for example, on directories that are writable by
untrusted users.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* Solaris 9 with patch 114356-12 or later
* Solaris 10 with patch 123324-03 or later
x86 Platform
* Solaris 9 with patch 114357-11 or later
* Solaris 10 with patch 123325-03 or later
