openvpnserv.exe (aka the interactive service helper) in OpenVPN 2.4.x before 2.4.6 allows a local attacker to cause a double-free of memory by sending a malformed request to the interactive service. This could cause a denial-of-service through memory corruption or possibly have unspecified other impact including privilege escalation.
Slackware 13.1, 13.37, 14.0 and 14.1 contain world-writable permissions on the iodbctest and iodbctestw programs within the libiodbc package, which could allow local users to use RPATH information to execute arbitrary code with root privileges.
