DESCRIPTION:
A vulnerability has been reported in Mongoose, which can be exploited
by malicious people to cause a DoS (Denial of Service) or compromise a
vulnerable system.

The vulnerability is caused due to an error in the "put_dir()"
function (mongoose.c) when processing HTTP PUT web requests. This can
be exploited to cause an assertion error or a stack-based buffer
overflow.

Successful exploitation may allow execution of arbitrary code, but
requires the server to be compiled with the "-DNDEBUG" option.
 
The vulnerability is reported in version 3.0. Other versions may also
be affected.

SOLUTION:
Fixed in the Mercurial repository.

PROVIDED AND/OR DISCOVERED BY:
Reported by Nico Golde to the oss-sec mailing list.
