Solution Type Sun Alert
Solution 233761: Security Vulnerability in the ipsecah(7P) Kernel
Module May Lead to System Panic
Bug ID: 6616749
Product: Solaris 10 Operating System
Date of Resolved Release: 28-Feb-2008
SA Document Body
Security Vulnerability in the ipsecah(7P) Kernel Module May Lead
to System Panic
1. Impact
A security vulnerability in the ipsecah(7P) kernel module may
allow an unprivileged local user the ability to panic a Solaris
10 system that has been configured to run a key management daemon
for IPsec Security Associations. The error in the ipsecah(7P)
kernel module may result in a Denial of Service (DoS) condition.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 10 without patch 127111-09
x86 Platform
* Solaris 10 without patch 127112-09
Note: Solaris 8 and 9 are not impacted by this issue.
This issue affects only systems configured to use IPsec and run
a daemon registered to PF_KEY socket such as in.iked(1M). By
default no such daemon is running. To determine if such a daemon
is running, the following command can be used (as "root" user):
# echo "::walk netstack | ::print -t netstack_t
netstack_u.nu_s.nu_keysock | ::print -d -t keysock_stack_t
keystack_num_extended" | mdb -k
If any of the numbers returned is non-zero, then one of the zones
in the system is running the IPsec key management daemon and the
system is vulnerable.
To determine if in.iked(1M) is running, the following command can be used:
$ pgrep iked
3. Symptoms
If this issue has been exploited, system panic would contain the
following stack trace functions:
sadb_new_algdesc()
sadb_action_to_ecomb()
sadb_extended_acquire()
sadb_acquire()
stubs_common_code()
ipsec_out_select_sa()
...
4. Relief/Workaround
Until patches can be applied, sites may wish to disable IPsec
key management daemons and use static keys. See ipseckey(1M) for
details.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* Solaris 10 with patch 127111-09 or later
x86 Platform
* Solaris 10 with patch 127112-09 or later
