Multiple vulnerabilities were found in Mono, the worst of which allowing for the remote execution of arbitrary code.

2.  Impact Information


Mono is an open source implementation of Microsoft's .NET Framework.


Multiple vulnerabilities have been discovered in Mono and Mono debugger. Please review the CVE identifiers referenced below for details.


A remote attacker could execute arbitrary code, bypass general constraints, obtain the source code for .aspx applications, obtain other sensitive information, cause a Denial of Service, modify internal data structures, or corrupt the internal state of the security manager.

A local attacker could entice a user into running Mono debugger in a directory containing a specially crafted library file to execute arbitrary code with the privileges of the user running Mono debugger.

A context-dependant attacker could bypass the authentication mechanism provided by the XML Signature specification.

3.  Resolution Information


There is no known workaround at this time.


All Mono debugger users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-util/mono-debugger-2.8.1-r1"

All Mono users should upgrade to the latest version:

Code Listing 3.2: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-lang/mono-2.10.2-r1"
