TITLE:
Sun Solaris traceroute Commandline Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA17708

VERIFY ADVISORY:
http://secunia.com/advisories/17708/

CRITICAL:
Not critical

IMPACT:
Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
Sun Solaris 10
http://secunia.com/product/4813/

DESCRIPTION:
Przemyslaw Frasunek has reported a vulnerability in Solaris, which
can be exploited by malicious, local users to gain escalated
privileges.

The vulnerability is caused due to a boundary error in "traceroute"
when handling the "-g" and the "-s" commandline options. This can be
exploited to cause a buffer overflow by supplying more than 10 "-g"
parameters,  or to cause heap corruption by supplying a malformed
parameter to the "-s" option.

Successful exploitation allows arbitrary code execution, but only
gives the malicious user additional raw socket access privilege
(PRIV_NET_RAWACCESS privilege).

SOLUTION:
Apply patches.
