AusCERT Security Bulletin Summary
Operating System: Debian GNU/Linux 8
Impact/Access: Execute Arbitrary Code/Commands -- Remote/Unauthenticated
CVE Names: CVE-2020-10663 CVE-2013-0269
- --------------------------BEGIN INCLUDED TEXT--------------------
Package : ruby2.1
Version : 2.1.5-2+deb8u10
CVE ID : CVE-2020-10663
The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.1 has an
unsafe object creation vulnerability.
This is quite similar to CVE-2013-0269, but does not rely on poor
garbage-collection behavior within Ruby. Specifically, use of JSON
parsing methods can lead to creation of a malicious object within
the interpreter, with adverse effects that are application-dependent.
For Debian 8 "Jessie", this problem has been fixed in version
We recommend that you upgrade your ruby2.1 packages.
