Name of the Vulnerable Software and Affected Versions Phusion Passenger versions prior to 5.3.2

Description An issue was discovered in the switchGroup() function, specifically in the agent/ExecHelper/ExecHelperMain.cpp file. The set of groups, referred to as gidset, is not set correctly, resulting in randomness due to uninitialized memory. This randomness determines which supplementary groups are actually being set while lowering privileges.

Recommendations For versions prior to 5.3.2, update to version 5.3.2 or later to resolve the issue.
