SunOS contains a flaw in "/usr/bin/passwd" binary that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered when a local attacker creates a symlink to the password file and uses the "passwd -F" option, which will recreate the password file with increased attacker priveilges. This flaw may lead to a loss of integrity.
Currently, there are no known workarounds or upgrades to correct this issue. However, Sun Microsystems has released a patch to address this vulnerability.
