Sun Alert ID: 57598
Synopsis: Security Vulnerability With Solaris Volume Manager (SVM)
Category: Security
Product: Solaris, Solaris Volume Manager (SVM)
BugIDs: 5046783

1. Impact

A local unprivileged user may be able to panic Solaris 9 systems which have Solaris Volume Manager (SVM) devices configured. This is a type of Denial of Service (DoS) attack.

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform

Solaris 9 without patch 113073-13

x86 Platform

Solaris 9 without patch 113994-22

A system is only vulnerable to this issue if SVM devices are configured, which can be determined by running the metastat(1M) command. If SVM devices exist, output will be similar to the following:

    d0: Mirror
       Submirror 0: d10
         State: Okay         
       Pass: 1
       Read option: roundrobin (default)
       Write option: parallel (default)
       Size: 4198392 blocks

    d10: Submirror of d0
       State: Okay         
       Size: 4198392 blocks
       Stripe 0:
          Device     Start Block  Dbase State   Hot Spare
          c0t1d0s4          0     No    Okay

Note: Solstice Disksuite (SDS) 4.x is not affected; hence Solaris 7 and 8 with SDS installed is not affected.

3. Symptoms

Should this issue occur, the system will produce a stack trace similiar to the following:

    vpanic(......)
    vmem_hash_delete+0xdc(.....)
    vmem_xfree+0x1c(.....)
    mirror_admin_ioctl+0x888(......)
    md_admin_ioctl+0x130(.....)
    mdioctl+0x90(......)
    ioctl+0x184(......)
    syscall_trap32+0xa8(......)
