DOCUMENT ID: 57453
SYNOPSIS: The pfexec(1) Command May Execute a "Profile" Command With
Additional Privileges
DETAIL DESCRIPTION:
Sun(sm) Alert Notification
* Sun Alert ID: 57453
* Synopsis: The pfexec(1) Command May Execute a "Profile" Command
With Additional Privileges
* Category: Security
* Product: Solaris
* BugIDs: 4925561
* Avoidance: Patch
* State: Resolved
* Date Released: 29-Jan-2004
* Date Closed: 29-Jan-2004
* Date Modified:
1. Impact
A local unprivileged user with a custom rights profile (see
profiles(1)) may be able to execute a profile command with greater
privileges than originally assigned, if the execution profiles
database (exec_attr(4)) contains an invalid entry for that custom
rights profile.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 8 without patch 109007-15
* Solaris 9 without patch 116237-01
x86 Platform
* Solaris 8 without patch 109008-15
* Solaris 9 without patch 116238-01
Notes:
1. Solaris 7 is not affected by this issue.
2. The modification of the exec_attr(4) file requires "root"
privileges.
The pfexec(1) program is used to execute commands with the attributes
specified by the user's profiles in the exec_attr(4) database. A user
must be part of an execution profile in addition to the default
profiles of "Basic Solaris User" and "All". A user can determine which
profiles they are part of by running the profiles(1) command, as in
this example:
% profiles
Basic Solaris User
All
3. Symptoms
There are no reliable symptoms that would show the described issue has
been exploited to gain unauthorized elevated privileges on a host.
SOLUTION SUMMARY:
4. Relief/Workaround
There is no workaround. Please see the "Resolution" section below.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* Solaris 8 with patch 109007-15 or later
* Solaris 9 with patch 116237-01 or later
x86 Platform
* Solaris 8 with patch 109008-15 or later
