Integer Overflow Vulnerability in Perl May Lead to Application Crash or Code Execution


Release Phase

Solaris 10 Operating System

Bug Id

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.

CVE-2005-3962 at:

Contributing Factors

This issue can occur in the following releases:

SPARC Platform

  • Solaris 10 without patch 119985-02

x86 Platform

  • Solaris 10 without patch 122082-01

Note: Solaris 8 and Solaris 9 are not affected by this issue.

This issue only affects Perl versions 5.8.0 and later. Solaris 10 ships with Perl 5.6.1 in "/usr/perl5/5.6.1/" and Perl 5.8.4 in "/usr/perl5/5.8.4/". The patches for this issue only apply to Perl 5.8.4.


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.


This issue is addressed in the following releases:

SPARC Platform

  • Solaris 10 with patch 119985-02 or later

x86 Platform

  • Solaris 10 with patch 122082-01 or later
