Description

The NFS daemon (aka nfsd) in Sun Solaris 10 and OpenSolaris before snv_106, when NFSv3 is used, does not properly implement combinations of security modes, which allows remote attackers to bypass intended access restrictions and read or modify files, as demonstrated by a combination of the sec=sys and sec=krb5 security modes, related to modes that "override each other."

Affected products

• Sun Opensolaris: snv_01, snv_02, snv_03, snv_04, snv_05, snv_06 (+84)
• Sun Solaris: 10.0
• Sunos: 5.10
