Overview
Affected versions of this package are vulnerable to Command Injection via the buildUnixUserList function in UnixUserGroupBuilder. An attacker who can influence a username in Unix group-member data can execute arbitrary OS commands by having synchronization process a username containing shell metacharacters, which the function concatenates into an id -G command passed to bash -c. This path is used when NSS is enabled and group-member enumeration is enabled.
