DESCRIPTION:
A vulnerability has been reported in Network Security Services (NSS),
which can be exploited by malicious people to compromise an
application using the library.

The vulnerability is caused due to the "NSS_NoDB_Init()" function
incorrectly constructing a file path for the "pkcs11.txt"
configuration file. This can be exploited to load arbitrary security
modules via the "library" directive when a configuration file is
loaded from a remote WebDAV or SMB share.

Successful exploitation allows execution of arbitrary code.

SOLUTION:
Fixed in the CVS repository.

PROVIDED AND/OR DISCOVERED BY:
Reported by hclam in a bug report.
