Solaris 10 Operating System

Bug Id
6368763

Date of Resolved Release
28-FEB-2006

Impact

An unprivileged local user may be able to cause a Perl application to crash or possibly execute arbitrary code with the privileges of the Perl application due to an integer overflow in the Perl_sv_vcatpvfn() function.

Being able to crash a Perl application is a type of Denial of Service (DoS). If the Perl application accepts input from remote users then the impact can be extended to include remote unprivileged users.
