Discussion
Solaris arp Vulnerabilities
It is possible to read bin owned files to which read access is not permitted to local users through exploiting subtle vulnerabilities in arp and chkperm.
With arp, this is done through specifying a file with the -f parameter . When arp tries to interpret the contents of this file (opening and reading it just fine being sgid/suid bin), it will fail and print the "erroneous lines" of the file along with its error messages. Those "erroneous lines" are the contents of the file to which you do not normally have read access (and belong to the user/group bin).
Solaris 2.x are known to be vulnerable.
