Affected Packages

------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-util/mono-debugger < 2.8.1-r1 >= 2.8.1-r1 2 dev-lang/mono < 2.10.2-r1 >= 2.10.2-r1 ------------------------------------------------------------------- 2 affected packages

Impact

===== 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.

Workaround

There is no known workaround at this time.
