Description

Tino Keitel has reported a security issue in RunIt, which potentially can cause a process to run with escalated group privileges.

The security issue is caused due to an integer type definition error in "uidgid.h". This can cause the group permissions of a process to be incorrect changed to the "root" group when "chpst" is used to set the permissions of a process using the "-u" option with multiple group names.

Successful exploitation requires that "chpst" is compiled against the dietlibc library.

The security issue has been reported in version 1.3.3 and affects only the x86 platform. Other versions may also be affected.

Solution
Update to version 1.4.1.
