High

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
su-exec through 0.3 fails to validate numeric user and group identifiers parsed with strtol before assigning to uid t and gid t, allowing truncation of out-of-range values to zero. Attackers can supply large numeric identifiers that truncate to root's identifier, causing su-exec to execute target programs with root privileges instead of intended unprivileged accounts.
