IMPACT:
Privilege escalation

WHERE:
Local system

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

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

The vulnerability is caused due to an error in the "getpwnam()"
family of non-reentrant functions provided by the  "libpkcs11(3LIB)"
library. This can be exploited by local users to execute arbitrary
code with escalated privileges if a privileged application is linked
with the library and uses the data returned by "getpwnam()" and
related functions. 

The vulnerability has been reported in Solaris 10 on both SPARC and
x86 platforms.
