Mono is prone to a local privilege-escalation vulnerability.
An attacker could exploit this issue by enticing an unsuspecting victim to run an application in a directory containing a malicious library file with a specific name. Exploiting this issue allows local attackers to execute arbitrary code with the privileges of the user running the affected application.
Mono 2.4.3-2 is vulnerable; other versions may also be affected.
