Sun(sm) Alert Notification
* Sun Alert ID: 102978
* Synopsis: Security Vulnerability in the rcp(1) Command May Allow
Execution of Unintended Commands
* Category: Security
* Product: Solaris 9 Operating System, Solaris 10 Operating System,
Solaris 8 Operating System
* BugIDs: 6473508
* Avoidance: Patch, Workaround
* State: Resolved
* Date Released: 10-Jul-2007
* Date Closed: 10-Jul-2007
* Date Modified:
1. Impact
A security vulnerability in the way the rcp(1) command invokes helper
applications may allow a local unprivileged user (or a remote user in
the case of shared filesystems) to create files with specially crafted
file names which could lead to the execution of arbitrary commands
with the privileges of a local user when that local user executes the
rcp(1) command on the specially crafted file names.
Note: The scp(1) utility is also affected by this issue which is
described in the following documents:

Sun Alert 102961 at:
http://sunsolve.sun.com/search/document.do?assetkey=1-26-102961-1
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 8 without patches 110670-04 and 114669-04
* Solaris 9 without patch 114716-05
* Solaris 10 without patch 121132-03
x86 Platform
* Solaris 8 without patches 110671-04 and 114670-04
* Solaris 9 without patch 114717-05
* Solaris 10 without patch 125794-02
3. Symptoms
There are no predictable symptoms that would indicate the described
issue has been exploited to execute arbitrary commands.
4. Relief/Workaround
This issue will only occur if the rcp(1) command is executed on files
that have specially crafted file names. Therefore, it may be possible
to work around this issue by avoiding the use of the rcp(1) command on
untrusted file names, for example, in directories that are writable by
untrusted users.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* Solaris 8 with patches 110670-04 and 114669-04 or later
* Solaris 9 with patch 114716-05 or later
* Solaris 10 with patch 121132-03 or later
x86 Platform
* Solaris 8 with patches 110671-04 and 114670-04 or later
* Solaris 9 with patch 114717-05 or later
* Solaris 10 with patch 125794-02 or later
