Multiple Security Vulnerabilities in rdesktop May Lead to Execution of Arbitrary Code or Denial of Service (DOS)

1. Impact

Multiple security vulnerabilities in the Remote Desktop Protocol (RDP) Client (rdesktop.1) may allow remote unprivileged users to execute arbitrary code with the permissions of the local user or lead to a Denial of Service (DoS) if rdesktop is used to connect to an untrusted RDP server.

These issues are described in the following documents:


2. Contributing Factors

These issues can occur in the following releases:

SPARC Platform

• OpenSolaris based upon builds snv_85 through snv_99
  

   
x86 Platform

• OpenSolaris based upon builds snv_85 through snv_99
  

Notes:

1. Solaris 8, 9 and 10 are not affected by these issues.

2. Only OpenSolaris installations including the affected binary "/usr/bin/rdesktop" are impacted by this issue.

3. OpenSolaris distributions may include additional bug fixes above and beyond the base build from which it was derived. 

The base build can be derived as follows:
  

$ uname -a
SunOS osolsys 5.11 snv_86 i86pc i386 i86pc

3. Symptoms

There are no predictable symptoms that would indicate these issues have been exploited to execute arbitrary code or cause a Denial of Service (DoS).

4. Workaround

There is no workaround for these issues. Please see the Resolution section below.

5. Resolution

These issues are addressed in the following releases:

SPARC Platform

• OpenSolaris based upon builds snv_100 or later

x86 Platform

• OpenSolaris based upon builds snv_100 or later
