Title
=====

Two Sun Microsystems Security Advisories:

1. Security Vulnerability May Allow An Unprivileged Local User
to Gain Root Access or Panic the OS

2. Security Vulnerability Using find(1) to Search "/proc" May
Cause a Denial of Service (DoS) Condition

Detail
======

1. On Solaris 10 x86 systems, or on Solaris 9 x86 systems with patch
112234-11 or 112234-12 or patch 117172-16 (or later) installed,
a local unprivileged user may have the ability to gain root access or
panic the Solaris operating system.

2. A local unprivileged user running find(1) against the "/proc"
filesystem may panic the system, creating a Denial of Service (DoS)
condition.

Sun(sm) Alert Notification
* Sun Alert ID: 102066
* Synopsis: Security Vulnerability May Allow An Unprivileged Local
User to Gain Root Access or Panic the OS
* Category: Security
* Product: Solaris 9 Operating System, Solaris 10 Operating System
* BugIDs: 6293270
* Avoidance: Patch
* State: Resolved
* Date Released: 11-Jan-2006

1. Impact

On Solaris 10 x86 systems, or on Solaris 9 x86 systems with patch
112234-11 or 112234-12 or patch 117172-16 (or later) installed,
a local unprivileged user may have the ability to gain root access or
panic the Solaris operating system.

2. Contributing Factors

The issue can occur in the following releases:

x86 Platform
* Solaris 9 with patch 112234-11, 112234-12 or 117172-16 or
later and without patch 118559-19

been exploited to gain root access. The unprivileged user may cause
Solaris to panic (with a corresponding stack trace that includes
functions from the mm(5) driver).

The system will panic with a stack trace similar to the following:
recursive rw_enter, lp=XXXXXXXXXXX wwwh=XXXXXXXXXXX thread=XXXXXXXXXXX
vpanic()
as_fault()
pagefault()
trap()
ktl0()
uiomove()
gfs_readdir_emit_int()
gfs_readdir_pred()
