Scientific Linux Security Update : ruby on SL7.x x86_64
Medium Nessus Plugin ID 79658
Synopsis
The remote Scientific Linux host is missing one or more security updates.
Description
Multiple denial of service flaws were found in the way the Ruby REXML XML parser performed expansion of parameter entities. A specially crafted XML document could cause REXML to use an excessive amount of CPU and memory. (CVE-2014-8080, CVE-2014-8090)
A stack-based buffer overflow was found in the implementation of the Ruby Array pack() method. When performing base64 encoding, a single byte could be written past the end of the buffer, possibly causing Ruby to crash. (CVE-2014-4975)
All running instances of Ruby need to be restarted for this update to take effect.
Solution
Update the affected packages.
