iDEFENSE has discovered a vulnerability in Perl and ActivePerl, which potentially can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error within the "win32_stat()" function. This can be exploited to cause a buffer overflow by passing an overly long filename with a backslash appended at the end to the function.

Successful exploitation may allow execution of arbitrary code on a system where it is possible for a person to supply a specially crafted pathname to a Perl script (e.g. on a web server).

The vulnerability has been reported in Perl 5.8.3 and prior for Windows.

Solution
The vulnerability will reportedly be fixed in Perl 5.8.4.
