SYSTEMS AFFECTED
Netsnap Webcam
PROBLEM
SNS Research found following. Netsnap is a webcam software
package for Win95/98/NT/2k which in addition to filming and
picture taking allows the user to directly publish his/her footage
to the web. To do this, Netsnap is equiped with its own
HTTP-server. Netsnap can be found on vendor Pelesoft's Netsnap
site.
There's a problem in the handling of GET requests by named server.
An unchecked buffer here can be overflowed by a string of
approximately 342 bytes, effectively crashing the server and
allowing the execution of arbitrary code.
SOLUTION
After discussing this issue with the vendor, Pelesoft have
released version 1.2.9 of their Netsnap software, which eliminates
the problem. Users are encouraged to obtain the new version asap.
