Scientific Linux Security Update : perl on SL6.x i386/x86_64

High Nessus Plugin ID 61169


The remote Scientific Linux host is missing one or more security updates.


Perl is a high-level programming language commonly used for system administration utilities and web programming.

A heap-based buffer overflow flaw was found in the way Perl decoded Unicode strings. An attacker could create a malicious Unicode string that, when decoded by a Perl program, would cause the program to crash or, potentially, execute arbitrary code with the permissions of the user running the program. (CVE-2011-2939)

It was found that the 'new' constructor of the Digest module used its argument as part of the string expression passed to the eval() function. An attacker could possibly use this flaw to execute arbitrary Perl code with the privileges of a Perl program that uses untrusted input as an argument to the constructor. (CVE-2011-3597)

All Perl users should upgrade to these updated packages, which contain backported patches to correct these issues. All running Perl programs must be restarted for this update to take effect.


Update the affected packages.
