Scientific Linux Security Update : ruby on SL4.x, SL5.x i386/x86_64

Critical Nessus Plugin ID 60442

Synopsis

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

Description

Multiple integer overflows leading to a heap overflow were discovered in the array- and string-handling code used by Ruby. An attacker could use these flaws to crash a Ruby application or, possibly, execute arbitrary code with the privileges of the Ruby application using untrusted inputs in array or string operations. (CVE-2008-2376, CVE-2008-2662, CVE-2008-2663, CVE-2008-2725, CVE-2008-2726)

It was discovered that Ruby used the alloca() memory allocation function in the format (%) method of the String class without properly restricting maximum string length. An attacker could use this flaw to crash a Ruby application or, possibly, execute arbitrary code with the privileges of the Ruby application using long, untrusted strings as format strings. (CVE-2008-2664)

Solution

Update the affected packages.
