Solaris 10 Operating System
Date of Resolved Release
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.

There are no reliable symptoms that would indicate the described issue has been exploited to execute arbitrary commands with the privileges of the affected Perl application on a host. The symptoms of the Denial of Service would be the Perl application no longer running.
There is no workaround. Please see the "Resolution" section below.
